'64 ammeter

[Don B.]

I'm trying to identify how the ammeter is actually connected in my '64 coupe. The wiring diagram in my Assembly Instruction Manual seems to have a problem since both wires (blk/wht & blk) go to +12v on the diagram. Both of the two wires from the ammeter go through the right hand firewall connector. The B/W goes to the horn relay where a lot of red wires are connected together (+12v distribution) and the black wire goes to the battery terminal on the starter solenoid according to this diagram. There must be a mistake somewhere.

No there's no mistake in the diagrams, its just not a true "amp meter", but rather a voltage differential meter. The very small difference in the two voltages indicate whether it is charging or discharging.

I've got a good paper on that. Send me an e-mail.

GM Donald -

If the meter is a differential voltmeter, it must be a sensitive one measuring millivolts. The wire sizes are substantial between where the voltages are sampled. However, this would certainly explain my confusion.

Is that paper OK to post here?

I'd like to second that Duke. It would be helpful to the rest of us 64 owners to have access to some more information. Thanks in advance.

Re: '64 ammeter

I don't see why not, but the diagrams embedded in the MS Word file won't come through, so that may limit its value. You can try if you like.

I didn't write it, and I forgot who sent it to me.
