Motor is a 72 2.2 that has bumped out to a 2.5. It has an internal regulator. Can i use this without and external regulator or do i need to convert. The motor is carbed and there is no cicuit board in the car at all. MSD 6AL, Soft Touch Rev Controller, MSD Tach Adapter all already installed. Not sure how much of the wiring harness that came with the motor I need to save. (IMG:http://www.914world.com/bbs2/html/emoticons/blink.gif)

You'll only need the relay board for circuits that need fuses and relays. On my six, I have an internally regulated alternator. I got rid of the relay board and wired up three generic bosch relays where the board used to be: 1 for the fuel pump, 1 for the heater fan, and 1 spare. Looks very tidy.
On the alternator, you should have three terminals: B+ goes to the starter or batter positive; ground goes to ground (duh), and DF (I think on mine it was labelled 61) goes to the generator dash light. The porsche tech bulletin on switching from an external to an internal regulator states some alterntators need a resistor put across the dash light to pull enough current to make the light go out. |
