Voltage drop at ballast resistor

OK with the switch on and bulkhead connector removed as I said earlier I get 11.8 volts at the blue wire with fusible link. If I disconnect the fusible link from the red wire leading from the starter relay I get the same voltage reading as the battery. Bad fusible link maybe? What tool is required to remove the pins from the bulkhead connector. I want to replace the fusible link.

Thx again.

Disregard this last comment. The voltage is the same through the fusible link to the bulkhead connector. Been messing with this thing since 0700 this morning. My back is killing me. Going to take 2 oxy and chill.

Thx all.
