My new diagram says to connect the 14 guage wire to the + terminal of the ammeter. Unfortunately, I removed all crumbling wires from the guage cluster before taking note of which one of the 2 ammeter posts had the 14 guage attached to it. The 2 posts are on a slight angle, one higher than the other. Can someone tell me which one is the + terminal. Thanks.

The ammeter should have a + and a - on the face. The -, or discharge side should be on the left as you face the gauge and the +, or charge should be on your right. The + terminal would be the post on the back side of the gauge behind the + on the front side of the gauge. This is how my little cartoon shows it.
I wonder what this 14 gauge wire is for? To my knowledge, all loads would come off the - (neg) side of the ammeter. That negative side would also be the connection point for any charging system output. I thought the only wire on the +, or positive side was at least a 10 gauge, and it went to a connection on the starter or starter switch that is commoon with BATT positive.
This is a wiring area where you want to be very clear on what goes where.

All other loads come off the - side. | | | | | Joined: Jul 2005 Posts: 2,031 Shop Shark | | Shop Shark Joined: Jul 2005 Posts: 2,031 | besure to cover the two posts (screws) after you wire it. for safety reasons.

I'll be sure to make the correct connection and check that 14 guage wire as well. Thanks Guys | | | | | Joined: Mar 2002 Posts: 9,115 'Bolter | | 'Bolter Joined: Mar 2002 Posts: 9,115 | The 14 gauge wire supplies the ignition key, which in turn supplies the coil and the gas gauge. This is an interesting point of the design because it is unprotected. The 10 gauge wire branches to supply the headlight switch and the battery terminal on the regulator.
On the other side of the amp meter there is only one connection and that comes from the battery junction feed on the starter. | | |
