Finishing up a complete restoration of my ‘59. I just installed a new fuel and temp gauge in my ‘59. Both sending units are new as well. When I took it apart a year ago neither worked. The new gauges are Omix ordered from KW. The fuel gauge works fine. With the ignition off the temp gauge needle is just to the right of the “C”. When I turn the ignition on the needle pins to the left even further past the “C”. I have taken it apart 3 different times and made sure there was no contact with the post and the housing. Does the same thing with the sending unit wire off. Wiring harness is brand new from Walcks. Everything else works perfectly. What did I do wrong? Bad gauge? bad sending unit?
