Hi guys, I’m working on repairing some electrical issues on my old car.
The gauges are a bit wonky, some don’t work and on the special occasion that they do they bounce up and down.
I am currently going through the wiring of the car, but one issue I (may) have found is the check control box which controls the gauges.
I took it apart last night, the circuit board looks fine, no broken lines or melted solder joints. But I did find this green diode(maybe?) that looked like it had gotten hot.
What is this green thing and is it something replaceable? It has 5%T7 written on it.
I am not an electronics wizard, but these little projects with my car are what I’m learning on.
A new check control module is $350, and before I drop that kind of cash I would like to prove that I need it!
Thanks in advance
Aaron
