77 international factory wiring problem
We bought our conversion about 2 months ago and all of the electric guages on the dash do not work( gas ,temp,oil pressure). We found a broken buss bar and thought that was the problem, but with a new one installed this weekend found out it isn't. Checked the wire that hooks to the buss bar from the gas guage and there wasn't any electricity. Ran a 12 volt wire right to this post and it seemed to work although not quite right. My question is where do I start to troubleshoot this and find my problem.
