One wire alternator overcharging battery

[69Zman]

One wire alternator overcharging.

I have tried two different powermaster alts and have a brand new battery, checked all connections/ grounds etc and still sending 17v to the battery. Any ideas here? thanks

check your voltage regualtor, but alternator should only put out 14-15v max

not running external regulator. Looking for open short or perhaps bad headlight relay etc. Thanks for the reply!

are they xs volt? if they are, there is a adjustment on the back, a small potentiometer. if not xs volt then?

even one wire alternators have voltage regulators internaly
Bad voltage regulator or a short in the alternator could cause this easily.
Really should do a 3 wire alt
but you did what you did for a reason
