13.6.2 Primary Alternator Connection

This entry is part 19 of 67 in the series 13 - Electrical / Instruments

Connecting the primary alternator is pretty straightforward. Basically 3 wires. The “B” lead which supplies the power to the electrical system. The “F” (or field) lead which is what activates the alternator and a ground wire.

Here you can see the large B lead (with the white cover on it). The F lead is above and routed to the left. And the ground comes around the right side.

I wasn’t happy with how the alternator cover looked so I did some more filling and sanding. The purpose of the cover is for cooling. Air from the plenum flows into the alternator and then out the bottom through a port.

Here’s the alternator with the cover on.

And where the wires exit the cover.
