what is the voltage regulator for?
What does it do?

Some smoke came out of my voltage regulator, during the engine was running.
I turned the engine off, removed the connector, and started the engine again.
But, I think the battery is not charged anymore. Is this right? Can I drive without an voltage regulator.

How can I find out, whether it is out of order or not?

When I want to buy a new one, what is important?

At rockauto I found those: (for a Chevy Impala 350 cui 1970),carcode,1048845,parttype,4884

What do they mean with 37, 42, 61 Ampere?

At harmons I found this: &s3=0

Here they write something about the ampere of the alternator?

What do I need? Is it specific for the alternator? If yes, how can I find out the ampere of my alternator?

The voltage regulator does just that, it regulates the voltage level supplied by the alternator. This prevents the alternator from overcharging the battery. The amperage they refer to is the output level in Amps for the three different options available in '70. This is good since all three alternators use the same regulator. I would use the one from Rock Auto, Standard Motor Products VR103T since its solid state (and much cheaper). Order the new one for $12.02 USD. The more expensive are "Original Relay" type (and expensive). The solid state devices work great.

Before you plug in your "new" regulator, make sure that none of the wiring is damaged or burned. Repair if necessary BEFORE plugging in the new device. Do NOT operate the car with the battery cable disconnected as this will harm the alternator and or the new regulator.

Viel Glück!

You can easily convert your car for an alternator with an internal regulator....then you can eliminate the old external regulator. Several kits out there and you get the benefit of higher amps.

I learned a LOOOONG time ago, that when you "let the smoke out" of parts, especially electronics, they dont work anymore!!!!

Sorry........I couldnt resist..........I still laugh at that when we talk about regulators, alternators, stuff that is electrical.

Again....Sorry, I know that you are in Germany, but there are so many great people here that can help you!!!!!!!!!!!!!

Good Luck
