OK - earlier thread about my oil temp gauge being erratic led the vast majority of you to suspect a grounding problem - that's why I'm posting this in the Electrical section. I'm totally brain dead when it comes to troubleshooting electrical problems. My problem is so basic I couldn't even find any tips in the Self Help Tips section. I found a very basic Sperry brand multimeter in my toolbox with markings for OHM, ACV, DCA, B.TEST, and DCV and the red and black probes coming out of the front. When you're all done laughing, can you point me in the right direction as far as using this thing to track down my gauge problem? Do I need a different instrument/tool? Does the bike's ignition have to be on or is this multimeter self powered? In other words does it send out its own current to test the continuity of the circuit being tested? What indications am I looking for, good and bad? Hard to believe my Dad was an electrician - he simply never shared any of his knowledge with me and I was too young and stupid to ask. Thanks, everyone.
