Re: whats this wire for ?

I think your talking about the junction block on the passenger fender. It is a distribution block for positive power wiring. Look up some schematics here if you'd like to know where those wires go.

It's also entirely possible you have an aftermarket positive cable with a small gauge lead that runs anywhere a previous owner wanted it to.

Probably the charge wire for your battery ,, they were ridiculously small from the factory

Thumbs up Re: whats this wire for ?

The block on the passenger side fender is to attach hot wires off of instead of the battery it self.

those glass fuses are for your amp meter there should be one on each side of the engine compartment

Never knew this! Exactly where are these fuses? Might be why my amp meter doesn't work.

Re: whats this wire for ?

I just replaced one today. Just look in the corner next to the pos. battery terminal. Follow the small gauge wire coming off the little distribution block there.
Then look in the area of the voltage regulator. Same size and color, same style pull-apart in-line fuse holder.

Well, checked mine and they were both blown. Grabbed 5 new ones from the parts store for 30 cents each. Popped them in and the gauge still doesn't work. I looked on the backside of the gauge and two of the posts are connected to the printed circuit board and the 3rd isn't coneected to anything. Not sure if it's supposed to be.
