Is that the only wire you have going from the regulator to the battery? That wire has to carry all the current to/from the battery in order for the gauge measure charging/discharging.

The wire just has to pass through those two loops on the gauge, it doesn't have to actually make contact with the gauge. The reason for this is the gauge simply measures the electromotive force (EMF) of the current flowing through the wire. The EMF opposes the force applied to the indicator needle by a magnet within the gauge that tries to keep the needle centered.

But it does seem to be the incorrect gauge of wire. Should be a lot larger gauge.

It just passes through - no contact.

Here is photo of the back of the gauge. Does the wire have to come into physical contact with any part of the loop or just pass through?

Are you sure there are two loops? I know zilch about how it works, but only know the wire goes through a single loop on the ammeter, without making contact with it. Also, it has to go through the loop in the correct direction or the gauge will read backwards, which may be why you see no reading. This wire is the main power for your gauges, lights, and ignition, so nothing less than 10 gauge will suffice.

It is an ammeter. I will change it to 10 gauge. Does,the wire itself have to make physical contact with a certain part of the “loops”on back of gauge or does just passing through the loops acceptable?

What kind of gauge are you using? If you are using an ammeter, you will have to use 10 gauge wire to adequately conduct the current. For a positive ground system, you will want to connect one end of the wire to the negative terminal of the battery and the other end to the terminal where all of the electrical load except for the starter will be fed.

Using new gauge. One continuous wire from - battery post (positive ground system) to “bat” post on the generator regulator. 16 gauge insulated wire runs through 2 loops located on back of gauge. Turn key on= no movement of gauge. Turn lights on = no movement. What am I doing wrong
