Is there a fast and easy way to determine the number of wires that should be attached to the ammeter in my 1935 Chev 1 1/2 ton w/ 207 CID. Some wires cut.

We can get you wired if you need that. Is your truck 100% original or have things been updated? Depending on your answer, I can help you. If you want to move forward, post good pics of back of ammeter so we have a good way to communicate.
Make a GOOD written and pictoral record of wiring and where wires go if you can. Then rewire with modern wire per wiring diagram. The dash cluster and/or gauges must come out. Gord's diagram, when zoomed up, looks pretty good. Use that and the one I posted together.
Note, I would expect the components to be too old to trust. They may not work at all. So I myself would update. I'm not hung up on nostalgic wiring and electrical components. I do like original dash, orig looking gauges, body, chassis, seats, interior, wheels.
I do realize however, that the dash and gauges are as simple as it gets. Very neat looking truck. You are lucky to find it.

A 1935 electrical system probably would be running a 3-brush generator, a cutout relay to disconnect the generator from the battery when the engine stops, and a circuit from the headlight switch to boost the generator output when the headlights are on. Before you start on a rewire job, you'll need to confirm that the above circuits are still there. Many, if not most 3-brush charging systems have been upgraded to a later model, higher output 2 brush generator with a 3-unit voltage regulator from the 1940s or newer. Jerry

It looks like the ammeter has two wires at each connection non the right side (looking at back of instrument) has about a 6” wire that is cut. The only electrical instruments are the gas gauge, and the ammeter along with the light switch. Along with the two instrument light bulbs.
