68 Dart wiring questions

Thanks again for the replies and info. The main reason I did the ammeter bypass like I did was that we don't have a dash cluster for him at the moment and I knew it wasn't safe to have the red and black ammeter wires lose in the dash so I connected them with a small bolt and taped it really well. Down the road I will look for a better and more permanent solution. As for monitoring charging for now, I will hook up a voltmeter from the aftermarket 3 gauge set we are using currently to monitor oil pressure and coolant temp once I get the alternator working.
