Just read what I wrote, I was still typing and editing. Do your testing over. You need to understand about testing. It is the key to troubleshooting. Without tests you have NO WAY to find problems. Can you or can you not take out cluster? If you did take it out, did you or did you not get gauge to work from grounding a cluster mounting ear. If not, take it out and get gauge to work from grounding at each ear, one at a time. (on the "bench"). See what you discover, that is what testing is for. Slowly realize where ground is lost. If all ears ground and gauge works, proceed to mount cluster. I assume you are using the sender each time you are testing gauge. I assume you keep checking voltage in case you loose voltage somehow during testing. You must not let two things happen at once or you will be in the nut house like I was until escape. This is taking too long because you are jumping to fast and wanting to do things like solder blobbing. Go back and test. You have the answer right there at your finger tips and rushing past it. I am with you Chris. You are going to get this. Watch your words, don't just say housing, be specific. One time housing was gauge, other time it was a cluster ear. CAN'T do that on a over the internet help forum. Tell where each end of test wire is connected on EACH test cycle. I guess your problem is you don't have a "bench" or a power supply so you are doing the best you can. It's still doable on the running board. Please read all several times I'm out of energy.
