REPLACING GENERATOR WITH
ALTERNATOR IN A TYPE I
After the new alternator is installed, you can physically remove the old
Disconnect the battery first.
Take the two fat RED wires on the B+ terminal on the reg and splice them with the fat RED wire that was on D+. You need a very good splice to do this. Twisting together with duct tape won't do <grin>.
One solution is an electrician's mechanical splice called a "bug". Get a small one. There are other suitable splice terminals available as well. Whatever you use, insulate it in shrink tubing or equivalent. You don't want this part to short out.
Types of splices
You now have three skinny wires left over:
Splice the Blue to the Green.
Tape up the Brown.
Back at the new alternator, connect the fat RED wire to the B+ terminal.
(I know; it was connected to D+ on the old generator.)
Connect the Green wire to D+ on the alternator.
This is the dash warning light connection.
That's it. The carb may have to be raised with a spacer.
The stock setup used a carb with an accelerator pump linkage which rotated clear of the alternator. You can also flop yours around to make it clear.
