That reminds me I need to fix my passenger door lock at some point... this 80 degree weather has it working about 2% of the time.

Problem returned today but I don't think I checked it after I removed the switch - so it might be in the door lock.

(I reconnected the door harness after removing the switch)

I went board level in the 2/76 controller

The ground is connected by logic command through the collector of a NEC 8413 NPN powe transistor , reputed through a 0.1 ohm power RESISTOR. I’ll be checking the NPN for collector emitter short

Here’s a nice picture from Sean’s rebuild showing where the 2/76 immobilizer controller sits. The white clips slide into the metal frame attached to the crash bar. You can get it out after removing the driver kick panel
