Boy today is a good one.lol. Noticed temp gauge isn't working. Oh, have a 1970 Javelin SST 390 4Sp.Replaced the sending unit and hooked up the wire found it wrapped around the harness. Still nothing.Won't move even with power on. unhooked the wire and turned the power on and used a volt meter .Put the red on the wire and black on ground.(bolt on frame). I get a beeping on and off from the meter. Digital meter.
Any Ideas or is it Shot???? Thanks for your time.
