Is this 0.08 ohm?

What resistance range did you use?

So far so good.

Can you measure the blue wire of the blue harness against a chassis ground, such as the cigar lighter ground.

It would be better if you can use the 200 ohm range.

Can you also measure the resistance between the blue and black.

There is no value between blue and black ,
No value for the blue wire (grounded with cigar lighter)

This is good news, the blue harness is in perfect health.

I like you you do some tests on the controller.

There are two rows of 15 test points. Systen ground is on the bottom left of the test points. This is where the black probe of your meter should go.

With the system at "per-crank" key position, please measure the voltage at:

TP4
TP5
TP8
TP11
TP15
TP16
TP17
TP18
TP20
TP23
TP30

You can use the 20V DC range.

Thank you very good infos

Now switch the gauge on still at pre-crank key position. Same TPs.

Sorry for taking so long trackdown the problem, it one is most unusual.
