Default '86 Clutch Start Switch

Hey Gang
I need info on readjusting the clutch start switch on a '86 DN 4+3.


I just replaced the clutch master cylinder/slave cylinder combo and now the car won't start unless the clutch start switch is bypassed.


The FSM Pg. 8-B-15 says to release a detent button on the switch body and push the switch forward and then press the clutch to the floor. to readjust the switch. The illustration the directions reference (8-B-3) is actually the washer nozzle aiming.


I can barely reach the switch, let alone find the detent button.




Any help/illustrations are greatly appreciated.
Jonathan.....

I havent heard of any adjustment on the switch but others have added spacer/shims in between the master cylinder and firewall. I just have mine bypassed but i also dont let others drive my car so i dont have to worry about them starting car with clutch out.

Same here. The rare times I have to take it somewhere for work, I post a big note on the dash that the switch is bypassed and talk to the person that will move the car ahead of time to insure they understand it will start in gear, or preferably I hang around and move it myself.
