I have a 73 mach 1 with some stating issues. How do I trouble shoot the neutral safety switch. The car came with the FMX transmission. so the switch is in the shiftier box.
Well I took the neutral safety switch out of the shifter box last night. The switch did not look bad so I check it out using a multimeter. The switch is bad, it has an intermittent short, if the switch is wiggled just right it works and then it doesn't work, tricky.The switch on a 73 should be on the transmission.
Neutral safety switch is in the shifter for Mustang/Cougar with FMX or with 429 C6. Search on "neutral safety" and "c9zx" for threads on cleaning the switch.
