Battery Gauge Wiring
When it comes to electricity I'm pretty ignorant so can someone explain to me how the battery gauge works? As I interpret the wiring diagram that came with my new wiring harness, the wire is not attached to the gauge but just passes through the metal loops on the back of the gauge on it's way to the circuit breakers. Is that right?

The original amp meters on these trucks used an inductive system. Current flow thru the wire thru the loop on the rear of the meter causes the meter to deflect relative to the direction and strength of the flow.

Thanks for the explanation. Per DW, I'll have to check and see if I put it through in the right direction.

Safety Tip
Since the original meter was an AMP meter this is not the safest meter to use.
Please read the Tech Tip on page 116 of the Ron Francis Wiring Catalog about NOT using an amp meter.

You do not want that much current running through your dash panel.
Be safe out there.

Looks like you bought the same harness that I did. I believe somewhere on that chart you will see the manufacture (USA Made), you can give them a call, I did, and they will answer any questions. Great company.

Temporarily wiring it up to fire up the engine. I used a Multimeter to ensure no ends were hot.

Philip, Thanks for bringing this issue to our attention. As DW has pointed out, this sounds like it's more of an issue for those who have upgraded their electrical system to 12 volts and are running an alternator. I think I'm going to risk it and stay with the original setup. Dan

I agree, it seems to be a pretty good product, especially for someone like me who doesn't really know what he's doing. So far it's been easy to follow the diagram and everything seems to be falling into place without any problems.

I bought it from Mac's. It's on page 46 of the current catalog. Make sure you get on their email list so you're notified of this weeks discount. It was 20% the day I bought it but it changes from week to week.
