The smell you found, it smelled like rotten egg correct? Double check the water level in the battery and see if that helps. But usually that would indicate the VR destroying the battery. Get a new VR (you'll want to do the 5 wire upgrade) and you may need a new battery.

Spot on diagnosis by Cad.

I'll add that if you don't address this quickly, you risk damaging more expensive items than the battery (ignition box, gauge cluster, etc.)

The ONLY running of this unit I would be doing is a 1 minute test to verify overcharging. (have voltmeter handy...start it up....connect tester leads to battery..rev it up and watch the meter reading....if it climbs past about 13.5Vdc or so, the regulator/rectifier-also known as 'the VR' needs to be replaced)

what does the 5 wire upgrade consist of and what years of vrs work on the 89 thanks for all the help
