Redcap Posted March 26, 2010 Share Posted March 26, 2010 My red wagon is showing some interesting charging idiosyncrasies. Sometimes, it will act normally and others the voltmeter will bounce a little, then climb sharply depending on RPM. I am replacing the alt today with a known good one, but was wondering if there was anything else I should consider as the culprit to the problem?

subiemech85 Posted March 27, 2010 Share Posted March 27, 2010 define overcharging! if you mean 18+ a wire is disconnected on the back of the alternator Quote Link to comment Share on other sites More sharing options...
Redcap Posted March 27, 2010 Author Share Posted March 27, 2010 Not quite that high, but it wasn't far off. Swapped the outboard alt for the inboard and deleted the AC at the same time. New alt seems to be functioning just fine. Quote Link to comment Share on other sites More sharing options...
hatchsub Posted March 27, 2010 Share Posted March 27, 2010 Usually overcharging is due to a faulty voltage regulator. I had one so bad that did that so i just turned on every single thing i could think of to bring the voltage down until i got to the JY and pulled a good alt.

Yo'J Posted March 27, 2010 Share Posted March 27, 2010 My alt was bucking out 18v for two short drives, thank god I noticed. The battery was swollen and started to spray acid! Quote Link to comment Share on other sites More sharing options...
