Suzuki X-90 Esoteric Off-Roadster

In reply to maschinenbau :

In Toyotaland, that is a classic symptom of solenoid contact wear on the Denso starters they used for decades.  I was hoping that your Suzuki used the same type of starter but it appears not to be the case.  No such luck.  You can get solenoids separately from starters but the solenoid costs nearly as much money as the whole starter assembly.

I have such a low opinion of aftermarket starters (and alternators, and most other parts) that it borders on hate speech.  Is there a locally-owned starter and  alternator shop you can take your unit to and have it repaired on site?  That's obviously not as commonplace as it used to be, but the odds always seem better if they guy doing the work has his name on the sign and has been there for decades.

Stating the obvious here, but it's worth checking the cables and connections down at the started end just in case someone has been in there making a mess of things.

Some digging shows there is a common "clicky starter" fix with these Suzukis because the solenoid is fed indirectly by the ECU or something like that, and it becomes a high resistance path over time. Plus it's just a spade connector on the solenoid. The fix is wiring a relay to power the solenoid more directly and they even sell kits. I may try "hot wiring" the solenoid to see if that's the issue, in addition to the normal troubleshooting like low battery and jump starting.

Got home. Checked battery voltage: 10.7v. Try to start, just a click and no turn over. Jumped it with my El Camino it started up okay. Alternator reads mid to high 12's at warm idle, goes over 13 with revs. I think it's charging fine.

Turned it off after a minute or two, up to 11.7V. So we're charging. But why was it low and why is it also random?

Some other important details: there is a battery kill switch under the dash that was added at some point in time. There is also a poorly wired radio and possibly an alarm that makes weird beeps. So it might have a slow battery drain, and perhaps someone got frustrated trying to chase it. I have not been using the kill switch.

Drove it around to get pizza, and it needed a couple tries of the starter again. The issue just seems randomly intermittent. So I tried to jump the solenoid by crimping a spade to a piece of wire. Seems to work! It feels like it cranks better this way, but hard to tell, because once I tried the normal way again it also started fine, though with a hesitation. So there may be something to the Suzuki "clicky starter issue". A-B-A testing is impossible with this issue, but now I have another tool in the glovebox to try in case its dead again. Because even if the battery is low, it should at least try to turn over.

I think it's a bad battery. I put it on the charger for like a day it won't budge above 11.9 V. Normal voltage when running. I still drove it in today despite it taking 4 hits with the key. 

I threw a new $70 walmart battery at it a few days ago and it's been starting better than ever. I'm calling it fixed.

I kept the old one and have been trying to rejuvenate it with my other better trickle charger, and it seems to be holding steady now, but we'll see. Always good to have a backup battery for project car shenanigans. 

Almost couldn't find a parking spot last night. Almost.

Battery drain is still a thing with the new battery. I've made a habit of measuring voltage right before and after driving. It's happy at 12.7V after driving. If it drains below 12V it has a hard time starting but still hasn't left me stranded yet. Turning the killswitch off definitely helps it keep voltage when parked. 

As part of Gambler prep, I installed a USB charger in place of the broken cig lighter. I also bought new knobs for the HVAC sliders. 

I also found this while digging around. It was wired to another non-OEM module, which was powered by a add-a-fuse. Guessing it's a security system. I unplugged the extra circuit to the module. and removed this backup battery. Battery still drained down to 12.0V overnight from 12.6V. Next step is borrowing a friend's current meter and pulling fuses until we find it. 

Gambler is next weekend and I'm running out of time to build a bumper. Still have some other maintenance to do. At the very least I need to focus on a skid plate. Or just send it. 

This thing is worth every penny when chasing a parasitic draw

Gambler 500 was a success! The X-90 was unstoppable and never missed a beat. Full update to follow but here's a teaser.

Once I heard about the return of the Georgia Gambler 500, I knew I had to go. And after my Miata wreck put me in need of a new car, I took it as an opportunity to try a new adventure.

Friday started out with battery issue, yet again. I definitely still have a draw, and it seems intermittent. Luckily I had charged the old new battery back up to good health, so I swapped it out and used the kill switch the rest of the weekend. I also wired the starter solenoid directly to a separate relay, so it will try it's hardest even with a low battery.

Then I picked up my buddy, loaded the hitch rack, and drove north.

The campsite was the field of a local dirt track, the Sugar Creek Raceway. They were gracious enough to host us and the dumpster, and even gave us discounted pit passes! We were looking forward to the races Saturday night.

After meeting up with more friends and setting up camp, we set off for a trail known for its water content.

Saturday we were awaken at 7am by a muffler-deleted Subaru Forester starting up and immediately pinning the rev-limiter, over, and over... After a breakfast and driver's meeting, we set off for some checkpoints to clean up some trash.

And trash we found.

Not only did we fill a roll-off dumpster, but we also filled a trailer full of used tires. The little Suzuki's trunk was pretty stinky!

I had a pretty good trail fix. A dirt biker's axle nut fell off, but luckily I had vise grips in the trunk.

The little Suzuki was UNSTOPPABLE all weekend long. The trails were very rough and rocky, but I had no clearance or scraping problems. The low-range was perfect for powering through mud holes and up rocky banks. And the ride was pretty smooth. My confidence in this car is unbridled. I would take it anywhere.

Saturday night dirt track racing was a blast to watch. Might have to give that try sometime...

If you're thinking about doing a Gambler 500, I highly recommend it. Good people, good times. If you're thinking about a Suzuki X-90, you should get one, because it may be the best worst vehicle ever made.

Photo no. 8 in your set above seems to be a Toyota Paseo – or at least the top half of it does. Any idea what the story is on that?

In reply to Stealthtercel :

It was a Paseo sitting on a Toyota truck or 4runner chassis I think.

got this listicle featured on my browsers home page and thought of this thread

Ha! Not sure I'd call it "Classic" yet! Just hit 2,000 miles of daily driving and I'm tempted to review my experience. Recall I am coming from a ND Miata and I've never owned anything taller than an El Camino. 

Like a Miata, it is intrinsically fun to drive. I genuinely enjoy bopping around town in it. But unlike one, it handles poorly and drives like a dump truck. The looong trucky shifter and nonlinear cable clutch feel actually make it more fun to drive, like you're literally driving a tiny Tonka toy dump truck. Perhaps this is touching on the "Jeep factor", or whatever it is people enjoy about driving lifted off-roaders. It doesn't ride uncomfortably stiff or anything like that, in fact it's quite soft over rough terrain, but you are certainly aware of the solid axle, short wheelbase, high center of gravity, and the un-sporty dynamics imparted by that combination. It's fine on the freeway, tracks straight and smooth, but anything over 70 feels too fast. And you will downshift for every hill, guarantee it. 

The seats are not very comfortable. I find the bottom cushion too long and flat and the non-adjustable headrests too low. The steering column is also not adjustable, so it always seems either my arms or my legs are slightly in the wrong position. I'm enjoying operating the early-2000's era stereo system, though the sound quality leaves a lot to be desired. When my wife is with me, we make it a point to only listen to late-90's music. The trunk is actually huge, way bigger than any Miata's and great for grocery shopping. Overall it's quite livable if you have a short commute like mine.

It's been reliable, other than the mystery battery drain. I use the battery kill switch every night and it hasn't been a problem since starting that habit. The A/C is not quite enough for the 90+ degree days here in Georgia. It's blows cold, but it just doesn't blow enough, and the relatively large greenhouse and glass roof allows the sun to heat up the cabin too easily. It's possible there's an airflow blockage because I sometimes get chunks of foam from the vents. I'm getting about 24 mpg combined, mostly city/suburban driving. It still burns oil, sometimes smells like it too. 

This car, or whatever it is, gets an unbelievable amount of attention from normal people and enthusiasts alike. Much more than my Miata ever got. It's a real crowd-pleaser at the gas pump, drive-thru lane, or car show.

Should you ever move on from it... I would like to call a pre-emptive 'dibs'.  I love these stupid little things. 

In reply to maschinenbau :

I get the "only listen ot late-90's music" bit. I believe that my '88 Porsche actually runs better when I play period music in addition to the interior being "tuned" for it.

While being in Japan, I would see these cars all the time and never really thought of them as much more than a sports coupe. However, after reading your journey with them and seeing the pictures of it ripping through mud and water almost as tall as it is, I have a new found appreciation and fascination with these cars haha. They are small but mighty. 

Still trucking along as a daily driver. I have a recurring EGR code that I just clear with my reader or cycle the kill switch. Sometimes the ABS light comes on too, but the kill switch cycle clears that one too. I will probably not diagnose these unless I get really bored :) 

I've resorted to tin foil to keep the flippy floppy vents pointed where I want them. Might try stick-on foam next. 

While this car always get thumbs-ups and compliments from fellow young to middle-aged car enthusiasts, I feel like their praise is always tongue in cheek, in the same ironic way that I also enjoy this car. "Dude, that's a RAD X-90 haha!"

But every time I go through the chicfila drive-thru, which living in Georgia means about every 36 hours or 45 miles whichever comes first, this car is met with genuine compliments and curious intrigue from a teenage girl who works there. They say it's cool, ask what it is, who makes it, etc. Every. Time. You can practically see the gears turning in their minds about what it'd be like as a first car. Teens these days seem really in to 1990's culture/aesthetic, so I guess that tracks? So now I wonder how many kids this summer have asked their gen-X parents for a Suzuki X-90 as their first car. 

If you can pop those dash vents out, you will probably find the remnants of some little felt friction pads that once kept them from flopping around. Should be easy to replicate if you are able to disassemble the, uh, assembly to get to those surfaces.

Fix those, and you will have the most refined X-90 in town.

EGR fault is occurring pretty frequently. Probably a clogged line or something. I'll fix it when I pull the head to do valve stem seals (lol never).

Met a friend at Pull-A-Part. Bubble or box, it's the same car underneath!
