First of all, I did a search on this topic and came up w/ nothing substantial. How do you troubleshoot a temp sending unit? I have refurbished factory gauges, they all function except for the temp gauge. Radiator has plenty of fluid, my radiator cap has a built-in gauge that reads 155 degrees at idle but, no reading on the dash gauge. Tested the gauge w/ a 9v battery and seemed to function fine. Any suggestions? '72 Sport/ 302. Thanks.
