Once we got the right tool to pull the drums off, yesterday's replacement of the rear wheel cylinders went fine. Now I am to the voltage regulator or more specifically the problem with the good battery not charging from the generator that will keep the car running just fine when the battery is disconnected. I see some soldering has been done inside the voltage regulator. I cleaned up the contacts and will clean up the connections but if that does not do the trick I will be looking for a source of a good regulator. Any suggestions?

Thanks

Barry

I've used Volkswagen voltage regulators for both voltages, and aside from slight modifications, haven't had any problem. The older 6 volt boxes were larger, but the smaller 12 volt units are almost identical in dimensions. Check on some of the VW aftermarket sites. Good source for 6 volt bulbs, Bosch generator and starter brushes, too.

You don't say 6V or 12V and 1962 could almost be either.

Try Jay at Yankee Trading in Riegelsville maybe an hour from you, about 10 minutes south of Easton . 1-610-559-1750 or 1-888-922-0072

Hello,

6 volt or 12 volt?

Sorry I neglected to include the voltage... 6.

Thanks for the advice.

I must be getting senile. My 1962 PV544 has a 12 volt system.

Hello,

I have in stock a Bosch electronic voltage regulator for a generator.

With an electronic regulator, you have no moving parts and better more consistant generator operation.

That's interesting. Is this listed by Bosch as a replacement for the old coils and points type or just a, probably, more expensive option? I've not seen any mention of this type in the UK for dynamo-genrator use. If it can help squeeze a little more out of a good running dynamo it would be a good option for those who don't want to change to an alternator for originality or other reasons.
Can you supply a part number please? Are they visually the same but with electronic innards?
Thanks.

Derek;

Be careful not to missinterpret Eric's statement of "better more consistant generator operation" to mean that you can get more out of the gen.

If a suitable solid state reg is available for generator systems, I would endorse it, for the reliability and repeatability advantages that electronic switching brings (more consistency in cut-in voltage, since there are no mechanical contacts which erode/wear to result in a change with age/use, and this is, I believe, what Eric means by "better, more consistent") but it can in NO WAY increase the output, sorry...remember, the reg only controls input current of Gen field coils...maximum output current available is determined by design and construction of gen, and speed at which armature turns (rate at which coils cut through magnetic lines of flux)...and you can't change that...the only thing we are in control of therefore, are external factors (which can and do make a difference).

If you want to "increase" the output of charging system, the importance of clean and tight connections in the path must be reemphasized...voltage drops across poor connections will effectively "decrease" charging system output! Ohms law review: Voltage difference is what causes current to flow, and this difference should exist between source (Gen) and load (Bat, Loads) only, not across any poor connections on the way...any resistance in the path will decrease current which flows.

Cheers

Hello,

The electronic regulator is a VW part. Bosch part number 30 019. I have ordered this number and sometimes have received the old style mechanical version so the correct long Bosch number is 9 190 040 099.

The connections are not the same and I usually make an adapter harness, but you can change the ends of the wires on the stock harness as well.

Ron is correct.

The regulator will not increase the amperage, but unless the engine is idling below 700rpm, it will charge at idle.

No. I didn't expect to get more out of the dynamo except by the solid state regulator being perhaps a bit more efficient/accurate/speedy at low revs where the dynamo suffers by comparison to an alternator. I've seen VW regulators used but they've had push on tags whereas the Volvo ones have ring tags and screws. The VW ones are easier to find but the Brazilian ones are sometimes poor. Copy ones aren't unknown.
Thanks for the number.
