If anyone has any electrical experience on these old 2L-T wiring harnesses I would love to hear from them. I have swapped in a 2L-TII into an 1989 LJ70, and the harnesses and glow plug rails are a bit different.
If anyone has any experience, with the 2L electrical system I would appreciate any guidance.
1. Battery has 12.5 volts, Main Glow Plug Timer illuminates dash light for 2 seconds per shop manual,
Main Glow Plug Relay is "clicking" when keyed to "ON", However I am getting zero volts on the glow plug rail when keyed to "ON" and "START"
2. Glow Plug Current Sensor has (2) wires that run up to the glow plug rail. The black wire has 6 volts when keyed to "ON" at the sensor connection. However, When a load is put on this wire / I run a jumper up to the bus bar, voltage drops to ZERO on the black wire. Does this sound normal to anyone? Or does anyone kow what may be causing this?
3. The Red wire at the Glow Plug Current Sensor has zero volts. (not sure if this is correct, since the shop manual directs you immediate to cracking open the timer relay which is crimped shut).
4. Is it possible to damage the glow plug timer relay or main glow plug relay by trying different wiring combinations?
If anyone could point me in the right direction, I would greatly appreciate it.
Regards,
Don
