BandY Posted January 27, 2015 Report Share Posted January 27, 2015 Just hoping for an easy answer to this mystery question. Had some help the other day, trying to get my 86 running, but it's still not able to be driven. Anyhow, this issue might be relevant, or it might be completely irrelevant. Holding a digital multimeter on the posts of my battery, the volts reading goes completely berserk while turning the engine over and/or running (however briefly that might be). Hooked the meter to his 89, and it held a steady reading, whether engine was running or not. Took his battery out and put it in my car, voltage still going crazy. Took my alternator belt off, and no change. Took some four gauge wire, and held another ground from the battery to the body, no change. Battery to engine, no change. So, can someone explain what this reading means, if anything? Sometimes a battery charger was hooked up, sometimes not. Made no difference. I read somewhere to wait an hour or more after charging. Is that relevant? Thanks for any knowledge, and/or opinion. Link to comment Share on other sites More sharing options...
Technology Posted January 27, 2015 Report Share Posted January 27, 2015 Is the voltage going higher than 12-14v? Going crazy and jumping around doesn't give us much. I would think ignition coil problem. Is the engine grounded to the chassis and battery? Link to comment Share on other sites More sharing options...

BandY Posted January 27, 2015 Author Report Share Posted January 27, 2015 I read somewhere that my copper core plug wires might do this, but I don't believe that. Link to comment Share on other sites More sharing options...
