do you use a voltage regulator with an Alternator

[bajababy]

last year i bought a 68 bug. the motor was shit so i bought a new one which had an Alternator already on it. now all i was woundering is if i still us the voltage regulator or would i have to bypass it in some way to use the Alternator?

Here's a post from an older thread which shows the differences in the single post with built in regulator, the 3 prong that uses external reg and older "Motorola" alternator.

You can't use the generator style regulator you had with any of them.

If the alternator you got with the engine is internally regulated then you need to just bypass the old regulator under the rear seat.
