1974 Scamp some assembly required

Fortunately, wiring for these is pretty easy. The biggest problems are brittle connectors and hardened or cooked insulation, which is part of the reason I'm not a fan of ammeters, generally speaking...I'd rather keep the major current paths out of the cabin.
Agreed. Luckily in 74 they already had the power wires that bypass the bulkhead connector and run through a separate grommet through the firewall. The wires, bulkhead connector and ammeter all look to be in good condition. Even still I don't think I'm going to fool with trying to use it. I will be using a voltmeter.
