Rapom's Rocket - just another Duster build thread

Hmm...thought I was getting somewhere. Cleaned up the wire ends at the amp gauge (again) and bolted them together with a short bolt and nut, removing the amp gauge. Probed that connection, plus the red wire at the ignition switch plug and got zero volt drop. Finally making some progress.

Turned the key on to probe the blue wire and I'm back to .75v drop on the blue wire. And the connection bypassing the amp gauge and the red wire at the ignition switch are showing voltage drop again. Key off, no drop. Key on voltage drop.

Could the ignition switch do that? Don't understand why I would see a drop before the switch.

I did try another switch earlier, but maybe it was bad too? It wasn't new, so I guess it is possible.

Good grief.
