My powermaster alt can't keep up with my fan

[KSW64]

I had the same issue back a few months ago. Start with the simple things like a worn belt. If you have v-groove belt and it has slipped at all, even tighten it will not help the charging problem. Feel the sides of the belt, if there is a ridge near the top, change it. It take about 6-9HP turn a alt at max output. Before you dig into too deep to your pocket book, try the simple things first.

Get one of these and stop guessing:

If you don't mind spending a little more the Hoyt indicators are built better. (You can had these off to your grandkids when you done using them.)

A voltmeter is almost useless in diagnosing charging systems.
