You can connect the positive and ground to the ones marked + and - (obviously) If it won't excite just like that, connect a switched wire from BAT + to the regulator terminal. You can use either an ignition switch or an oil pressure operated switch (find one used to run an hour meter). Or if you will use a battery disconnect, you can just jumper over from the + terminal on the alternator to the regulator terminal. Opening the disconnect will break the ground connection so the full time connection won't matter.
Sometimes a tachometer uses the AC output as a reference. I don't know what else someone might need the AC tap for. We have a couple of Delcos with an AC tap beside the normal regulator 2 prong plug)
Hi Wayne,
Was thinking Motorola the other day but actually meant Leece- Neville (known in the trade as "loose naval")
This is as close as I could get for a wiring diagram....actually out of their marine series. Should work fine with that 4-pole disconnect switch I recommended.
