Re: too many amps, need better alt?

Where is the volt meter connected? Under the dash?
Will have to chase it down to determine...

A PO installed a new harness, Painless I believe. It's going to be an adventure tracing down the leads to figure out exactly how it's all wired up. The gauge of the leads connected to the alt all appear to be on the small end of the scale and none of them make a direct path to the battery. Appears to me any path to the battery goes through the fuse box, probably through the volt gauge and through some other wiring that is definitely not of the proper gauge.

The cooling fans pull directly from the battery. If the alt doesn't really have a direct circuit to the battery, could the amp draw of the fans on the battery cause damage to the wiring ( possible fire ) between the alt and the battery due to the draw?

As you may have figured, I'm not a great electrical guru!
