alrighty... i recently replaced the alternator on my 82 yota and the volt regulator and when i first crank it charges fine but when i drive it goes to 16.7 its got me and a few mechanics puzzled. anyone have or have ran into this problem?

please help :b ang:

 

hey Shaney - did you get an answer?

I'm sorta in the same boat, noticed my volts gauge creeping on 18 (!) volts, dipping under it with the lights/stereo on in the evening...

voltage regulator going out perhaps? im not sure if yotas have internal or external (or if it vary's by year...), my old pontiac had in internal in the alternator that failed...

 

no i still havent figured it out yet but im now starting to think i have a bad ground somwhere

i recently poped the hood right after starting it and noticed a the ground from the battery was smokin a little but other then that ive been driveing it normal and it hasnt seem to hurt anything yet

 

I am having the same problem and I believe its the voltage regulator for mine but you said you replaced yours. There is always the slight possibility that you bought a bad part. Hmm...

 

yeah that is also true

maybe ill run it back and get another one to be on the safe side

and replace that ground while im at it
