Wtf is the problem here?

[Jaychen]

Guys I have a non working tachometer and temp gauge. They used to work intermidantly but one day just completely stopped working which makes me believe it some thing common. I have pulled the cluster taken a look over it , nothing seems to be wrong. Also checked the 'gauge fuse'; it is fine. CAN SOMEONE PLEASE POINT ME IN THE DIRECTION OF FIXING THESE TWO GAUGES. I do not want to install aftermarket gauges as I have a TurboA and want to keep it as stock as possible! PLEASE electrical wizards, chime in.

THANK YOU IN ADVANCE!!!

You really should use the EWD for your year. They share power, but it is shared with several things.

Mate, I am no electrical genuis, nor do I understand how to read that EWD picture of TRSM, but am always willing to learn. Would be so kind as to explain to me what I should be looking for, trying to fix, trying to find?

I would look at the circuit board for obvious physical damage.

is it just those two things that are not working? anything else?

 

[Jaychen]

Just those two things, to me the circuit board looked in perfect condition. I am stumped, please guys , help me out!

Have you traced the wires? Maybe one is burnt or has been smashed or chewed on and was cutting in and out and is gone now.
