Crawling under my 67 and while looking at the starter motor I noticed 2 smaller wires that run to what I assume is the earth post. Anyway only one wire is connected, I assume they both should be connected to this post is this right? I looked at the schematic but still not sure. The wire has no connector on the end.
Original starters used the yellow wire to deliver a full 12 volts to the starter solenoid when cranking.
Modern starters do not need that so do not have a connection for the yellow wire.
