gauges on the fritz
I currently have an 83 CJ7 with a 360 swap. My current issue are the temp and fuel gauges. I have read the article in the Electrical tech section. Right now I am currently reading a steady 12 volt on the middle posts, instead of the pulsed 5 volts. Both sending unit check out with appropriate resistances.
My question is, has anyone ever put a steady 5 volts there instead of the pulse? Will either work? I cannot think of a reason it has to be pulsed, except that a steady 5 volt could potentially burn the gauge out. Has this been done before? Any help would be great
