Good morning everyone!
Got a chance to drive the Scrambler a bit and found that the temp gauge did not work. So, following this trouble shoot guide Morris4x4 and a few others, I came up with the following:
Sending unit:
Cold: ~210ohms
~150 degrees: 48ohms (just a quick drive around the block, checked temp with an IR thermometer)
Purple/White wire SU to gauge: 2.7ohms
Gage S to A: 21.00ohms
Jumper voltage: Bounced between ~1.5V & 7.0V
This all seems in spec. I found a 57ohm & 10ohm resistor, so I jumped the S terminal to a ground expecting the needle to move, and nothing.
So, just a bad gauge?
EDIT: Fuel gauge works, though seems to read about 1/4 lower than it should be (F @ full tank, 1/2 @ ~3/4 tank)
Thank you in advanced for your help!
