Amp Gauge ?
I'm trying to get my factory amp gauge to work. I've tried 2 different factory gauges, and no luck. I have did a continuity check on the circuit from the battery junction block to the dash panel plug (both fuses are good). All checks out good. I have a constant 12 volts into the gauge and out the other side of the gauge whether the engine is running or not. Is this supposed to have constant 12 volts there? Does anyone know what the ohm readings are supposed to be across the amp gauge terminals?
Any other ideas? Oh, I did rewire my alternator for a internal regulator per FAQ on here. Charging system is working fine. steve

Check this:

Re: Amp Gauge ?
Just a regular 60 amp w/internal reg. Not a one wire alt.

Re: Amp Gauge ?
Here is a link that shows how to wire an ammeter in for a 66.It should be the same.

Re: Amp Gauge ?
pop off ur dash bezel WITH THE NEGITIVE OFF THE BATTERY REMOVED. have some one hold the dash (to keep it from grounding.) re connect battery. get a tester on the back of the amp gauge, positive on one post, ground the other. need more info, pm me.
trust me, that gauge is hot 24/7 (as long as the batt is connected) i fried my brand new circut board by letting the post's ground out on the frame while putting the dash back in. |

Re: Amp Gauge ?
Thanks to all for those ideas. From what I have been reading on here and elsewhere, is to go with a volt meter instead. I'll try a few of those other ideas mentioned, and then see.
