'66 Mustang Coupe, 302 V8, C4 Auto
New battery
Neutral Safety Switch - functioning properly
Mini starter - works
I have searched these forums and read many threads on the subject, so please forgive me - I'm just not quite sure I understand everything. I'm using a set of colorized wiring diagrams and looking for a little verification.
I don't think I'm getting the right voltage at the coil. 12.3V on the big left post of the solenoid. When the key is turned to "Start", I see 12.2V on the red/blue wire to the "S" terminal, 12.2V to the "I" terminal, 12.2V to the far right terminal for the starter, and the starter motor operates. So far so good, right?
If I remove the brown wire from "I" and turn the key to "On", I get low voltage (0-300mV) on "I" and 12.1V on the brown wire. Turn the key to start, and I get 12.2V on "I" and the brown wire. Therefore, I also see 12.1V on the red/green wire to the coil when the key is in "On" and 12.2V when the key is in "Start".
I believe my starter solenoid is operating properly, but I think I'm seeing too high of a voltage to the coil when "On". The big pink wire is supposed to drop it to 7-9V, right? I should see 7-9V on the red/green coil wire, and 7-9V on the brown wire, right? Perhaps the pink wire has been bypassed? Best I can tell, the pink wire is connected to the brown and red/green wires at the main disconnect at the firewall. It disappears into a wiring loom between the main disconnect and the starter switch.
Thanks in advance,
Brian
