Wiring Issues with High Output Alternator

[qwik240z]

The guy who is doing my LS1 swap asked me to find out if anyone has had any problems by using a High Output (105amp) GM internally regulated alternator and just bypassing the stock Datsun Voltage Regulator?

 

He says that he has seen, on some older cars with older wiring, the stock chassis wiring fry up without the use of a factory voltage regulator and says he can use the internal regulator of the 105amp GM alternator for just the engine, ECU, fuel pump, and cooling fan wiring and retain the factory voltage regulator for all of the remaining chassis wiring.

 

I didn't recall hearing of any problems just bypassing the regulator but figured I better ask.

 

Thanks in advance!

I'm using the high out put version (105 amps) on my 73 with out the datsun external regulator. Works just fine.

I agree with Mark. Never heard of any problems. In fact it is a nice upgrade. The old alternators were marginal at best.

I can only think of two things that could go wrong. One would be the amp gauge. I would remove it and install a voltage gauge. The whole electrical system of the car goes through the amp meter. Just wire the large white and red wires together and bypass it. The second thing would be if you install a higher current draw item, like higher wattage headlights or stero amps. But the install of the new alternator wouldn't cause the wire to burn out. It would be the higher current draw of the headlights and the amps.
