Coil Questions (1 Viewer)

Hey Everyone,

I have read over the threads on 40 series coils and I cant find the info I need. I am putting my 1975 40 back together after five years and the labels have all faded off my wiring. What I need to know is where to plug the white wire with blue stripe that has power only when the key is turned to start(starter engaged). I have been scratching noggin over this.

I think the WL (white/ light blue stripe) goes to the B+ on your alternator. Maybe post up a pic of your harness.

Here is a pic of the 76 harness I have showing those connections.

Red to the distributor from the OEM igniter which you no longer have
Yellow/Black to oil pressure sending unit
Black/Yellow to starter from + side of coil (This is the ballast resistor bypass wire)
Black to - side of coil from OEM igniter

If you truck is running now how is the Pertronix wired? Draw a pic showing how the PO has it connected and post it up.

Where do these plugs go? (wire harness)

Sorting out the usual hacked up cruiser and I am trying to clean and repair the harness. The engine bay is stripped of all electrical parts. Some of the wires have bare spots and need replaced. Some of the ends look to me like they may not be factory original. I pulled all the black...

"Except for US and Canada" and the color codes don't even list blue in my Haynes B is black, I appreciate the link though

I did not notice that. This is North American spec.

The white and blue wire will be referred to WL in the schematic
