What we know?

• Cluster receives power when ignition is on
• Ground is good
• Lights on cluster work and receive power but no gauges work.
• I bench tested the temp gauge and fuel gauge and both worked when directly hooked to power
• Wiring colors we know
  • Black with yellow stripe is power
  • White with black stripe is ground
  • Black Tachometer
  • yellow with green stripe Water temp gauge
  • yellow with red stripe Fuel Gauge

What we don’t know
- we don’t know why power is not getting from the main cluster power to each gauge. I plan to do some more testing around this tomorrow.

My cluster has 2 round plugs from the harness. Both the main power in and the ground are on the same round plug. Both my fuel and Temp gauge are on the other round plug and despite them not working there are other dash lights that are powered off of that plug that do work.

I’m not very good with electrical so this has been a struggle. I’m looking for direction for other things to check or how to I narrow down the issue.

Please help thanks!
