Reply To: 6v to 12v on a Traction

Hi Tim,

Apologies I missed this so I hope you’ve sorted everything out by now. Anyway, I fitted a Lucas 17ACR which includes a regulator. I had to find a pulley for the wide belt. Can’t for the life of me remember where I got it but this one might do:

The alternator runs slower than it would normally, so I had to wire 2 warning lights in parallel to get it to charge at low revs. Even so the warning lights come on at idle. A smaller pulley on the alternator would help.

As you can see from the picture I bent a bracket from some flat steel which I will maybe get around to painting. 

Just off to the left of the photo you might spot a 12V to 6V solid state converter which feeds the wiper motor, fuel gauge and clock. That’s energised from a relay off the ignition switch.
