Magnum Alternator Wiring

Dusterfreak said

Hi, im having too high voltage when I get over 2000rpm. At idle it charges 14.3 and when I put up to 2000 it charges 17 to 18 volts. Regulator is bolted to the fender and I made an extra ground wire also. Regulator is new from rock auto, could it be broken otb?

Check and make sure ALL of your connections are good, tight, and CLEAN. No rust, corrosion, paint, etc. The ground is usually the problem but any of the connections can cause issues.

The regulator could very well be bad even though it's new. That is becoming so common its ridiculous.
