Ive been troubleshooting with Jeff and learned a few things
1- the green led is definitly not working. Hooked the green wire from the ecu harness to ground and only the amber and red lights came on
2- pump works no problem, hooked direct to battery and runs
Wiring and circuit board seems fine but the water level light would not go away even with the sensor disconnected!!
What else would trigger that light?
Check this short video of the gauge
