Wiring HEI distributor with mini starter
So I recently rebuilt my engine and in the process upgraded my points distributor to an HEI, and my factory starter to a mini starter. The factory starter had 3 terminals (Battery+, S, R), and the new starter has 2 terminals (Battery+, S). Based on the instructions and what I read online, the R terminal was the resistor wire bypass for the coil (so that the coil would have 12v on startup) and that for HEI distributors it could be removed (So I did just that). I also removed the resistor wire that was connected to the coil from the bulkhead connector, and replaced it with a 12-gauge wire (This will be the power for my HEI).
Note: I checked the wiring diagram and determined that this pin on the bulkhead connector ties into the ignition switch (12-P wire from the bulkhead on the factory wiring diagram)
So with the wiring set up as it is (to my understanding), when the key is in the RUN position the wire to the starter S terminal should read 0V and the 12-gauge wire to the coil should read 12V. Then when the key is switched to the START position, the wires to both the starter S terminal and coil should read 12V.
Upon testing, when the key is in the RUN position I am reading 0V to the starter S terminal and 12V to the coil (which makes sense). However, when testing with the key in the START position, I am reading 12V to the starter S terminal and 0V to the coil (which does not makes sense?). I also tested the IGN terminal on the fuse box and got the same results.
Unless I am mistaken, the HEI requires 12V in RUN and START. So is there a different terminal that I should be using instead of the IGN?
Thanks for the help!
