I put it in and SNAFU. I must have hooked up something wrong, because it did work on the test bench. I will look at it again with fresh eyes tomorrow. I am pretty confident that the problem is not with the sending unit. will advise
Edited Tuesday the 20th,
Ok someone figure this out for me. I have my modification installed and the cluster is hanging out of the dash. I am showing 36 Ohms on my ohm meter coming from sending unit. I carefully put the cluster into the dash and the resistance drops to zero. I have tried it many times and it happens every time.
I am off to the garage to figure out something else. If any one thinks of an answer to why it changes, leave a post and I come in at least every hour to check the board
