I'm enrolled at a tech school in an automotive collision repair and refinishing class. Currently I'm working on finishing up in my electrical systems. We have a nice set of A-Tech training boards which are GM based (off a cavalier). I'm having trouble finiding information of how to diagnose a few different types of issues: 1. Short to ground ( understand this one pretty well). 2. Short to Power ( understand this one also). 3. High Resistance Short (understand that the resistance reduces power considerably.) 4. Open again not a complete path. (easist to diagnose)
Basically I'm curious if anyone can tell me the ways to use the mulimeter to pinpoint each. Any help would be appreciated.
