I installed that this evening and put everything back together. It won’t start on the battery. The only thing I can think of that to me makes sense is that I’ve put the control box together wrong.

I need an exploded parts diagram or a few, good, detailed photos so I can make sure I have this thing right.

Seems like something is not wired up correctly or a component is U/S. If all else fails I would try to by-pass the ammeter and the cut out . I mean: try to connect your + battery lead directly to the + side of the circuit , you may have to remove the control box cover to try this.

You could have a dud rheostat. Does it check out OK with your multimeter ?
