Do I need a resistor between the alternator on the battery wire that's hooks to the starter. ? And do i hook the other alternator wire to the ammeter post correct. ? hook it to the load wire post that goes to the ignition ? Also would you hook up an inline fuse for the heater... And if so what size? And for the gas gage ? And what size?
I'm not clear on a couple of things... Are you using the original 6 volt gauges and heater motor? If so, then you'll have to place a proper voltage dropping resistor of adequate current carrying capacity for each of the 6 volt devices. As for the starter, you can run it on 12 volts with no problems, as long as you don't crank it excessively. The 6 volt starter has hefty internal wiring and will actually crank your engine better on 12 volts. Typically the 'other' wire on the alternator will be connected to become hot when the key is turned on. Others may elaborate on this some after reading my post, but I hope this will point you in the right direction. Bill
What alternator is it? Internal regulator, external regulator, one wire, or newer small diameter one? The most used one for years was the internal regulator one with the battery terminal on the back and an oblong slot on the side with two flag terminals numbered "1" and "2". Run short wire from #2 to battery terminal on back, a wire from "ACC" on the ignition switch to #1. 10 or 12 gauge wire from battery terminal on back of alt through ammeter to starter cable post on the starter. You're done. If ammeter reads backward switch the wires on the back of it. To keep from standing on your head under the dash you can run a wire from the + side of the coil to the #1 terminal but will have to put a diode in it so the engine will die when the switch is turned off. I don't like running other things off my ignition system but many do so.
