generator to alternator conversion
Well I can see that there have been a number of posts about this over
the years, but none of the other ones really answer my questions. I have a 1965 VW Type 1 (1200cc engine) and I am upgrading it from 6v to 12v, replacing all the normal things (generator with alternator, oil stand, coil, flasher relay, etc) plus the entire wiring harness. I've been plagued with electrical problems over the last 6 years and I am tried of it. I have a few questions about how to do this. -When I replace my fuel pump with the "alternator style" pump, does it matter what year? Like is it okay if it is a 1600cc 1973 pump? There aren't any 1965 alternator pumps for sale, obviously, but I wonder if the bigger engine size for which those pumps were designed matters to the amount of fuel that gets pumped into the carb. Can I basically use any pump that will screw into it and leave room for the alternator? I know i need to replace the pushrod. -Do I need to replace the distributor? It doesn't seem like it. -How do i re-wire my car for an alternator? I know that the wiring setup for the engine compartment, even when i replace it with a brand new one, will be configured for a generator. The regulator is mounted on top of the generator in my current setup, not under the back seat like it was in later models, and as a result I can't find any info online about doing it this way. Thanks for your help everyone! |

Fuel pumps for the alternator take the shorter pushrod IIRC.
I have done several conversions to 12V and have seen a few issues only on some. One Beetle I had to change the ign switch since it started smoking after receiving the 12V through it. The most difficult thing, after the gen or alt install, is the wiper motor. Also I needed the top of a 30PICT-1 to fit over the 28PICT carb. The starter I can leave untouched and wiper motor if you want turbo speed! lol A one day job and you have 12volts. <g> "Speedy Jim" > wrote in message et... > wrote: >> Well I can see that there have been a number of posts about this over >> the years, but none of the other ones really answer my questions. >> >> I have a 1965 VW Type 1 (1200cc engine) and I am upgrading it from 6v >> to 12v, replacing all the normal things (generator with alternator, >> oil stand, coil, flasher relay, etc) plus the entire wiring harness. >> I've been plagued with electrical problems over the last 6 years and I >> am tried of it.

I can't recall having that problem with the 1963 Beetle that I converted
over. I think I used the alternator on that one too.

The 6 volt starter gear has a larger shaft diameter than the 12 volt
starter. I think it would be possible to convert a 12 volt starter to a 6 volt ring gear but you would have to put a sleeve bushing in the 6 volt starter gear to match the 12 volt starter shaft. You would have to put a 6/12 volt reducer bushing in the transmission housing too. I tried putting a 12 volt solenoid on a 6 volt starter. It did not work because the throw on the 6 volt starter is longer and the 12 volt solenoid would not make up the contacts when put on a 6 volt starter. If anyone has made these conversions I would like to know how they got it done successfully. I ended up just using the 6 volt starter on 12 volts. It really kicks the engine over.

There is a guy on Samba that rebuilds wiper motors and can still put the 12
volt armature in the 6 volt wiper motor. It is pricey but looks stock without extra pieces.

Not The Right Way(TM), but 6V starter is very durable motor and will last many years if not overheated. I've a -63 KG and it was (by PPO) converted to 12 volts in 1992, I changed the engine last summer and as the new engine had 12V flywheel, I had to change the starter too. Easier to replace than flywheel with re-balancing everything etc.. So 14 years of regular usage (in summer, Jan surely has told about Finnish weather...) and nothing wrong so far, so I'd say it will last as long as any 12V starter if not overheated.
