Re: Amp Meter hook up

Dan, Ammeters are REALLY not recommended these days. The required wiring can be dangerous. A problem with the wiring at some future date could render the car inoperable, or even burn it to the ground...

If you REALLY want one though, it must be installed in series with the main charge wire to the battery. You'' need about twenty feet of TEN gauge wire, some terminals, heat shrink, and solder and soldering iron. The best place to tap it in is this lil terminal block on the drivers side of the rad support, you have to remove the battery to see it. There are 2 wires on the post, remove the one from the battery, and install one of your new wires in it's place. Connect your other new wire to the wire you removed. It's best to use some sort of solidly mounted insulated terminal block to do this. Run the 2 new wires into the interior and connect them to your gauge.

As I hope you can now imagine, if ANYTHING happens to your new wires, bad things are only moments away. If a connection shorts to ground, it could burn down your car.

I'd suggest buying a voltmeter instead.

Thank you Jim. I'm not sure this is the right way to go but my buddy is very sure he wants it this way.Would be a shame to burn down this nice 69 Z but he's the boss.Better make sure my ins is paid up.
Thanks again,Dan

Re: Amp Meter hook up

The terminal block I think JimM is refering to is on the pass side of radiator support next to the battery.

You could use the horn relay buss bar and use the wire crossing over to the junction block to hook to the gauge. Hook the other new wire from the gauge to the buss bar.

After hook-up, if gauge reads backwards, swap the two gauge leads.

Re: Amp Meter hook up

You're right, Everett, pass side of course, where the battery is.

On the horn relay side though, there is no easy way to get "only" the charge wire to the battery. That wire goes to the "main splice" and branches to the alternator and regulator, in addition to the horn relay. An ammeter hooked there would always read "discharge."

You could slice into the harness behind the drivers side headlight and take it there, but that's just making matters potentially worse.
