Dawgz83948 Posted October 30, 2011 Report Share Posted October 30, 2011 Ok here's the situation. My truck runs very well, but the temp gauge will range into the 220-230* range on a electric and get's very near to the last line on the cooling gauge. Here is the problem as best I can figure: I have a good ground both to the fender (body) and to the engine block on the head. My ohm meter registers .001 with the ignition off. With the key in the ON position however the resistence shoots up to 19-22 not .19 but 19-22. Needless to say this screws with the gauges a bit because it adds 19-22 ohms to the ground. I've replace the negative wire and connected a second ground to the engine. I've replaced the voltage regulator and the fuse box with an updated fusebox that I wired myself (yes the problem was there with the stock fusebox before I rewired) Any takers???? Any suggestions?

DanielC Posted October 30, 2011 Report Share Posted October 30, 2011 Here, read this. http://www.vernco.com/Sparks/id606.htm Basically, an ohmmeter runs so little current through a circuit that the resistance appears not to be a problem. But when you run a lot of current through even a small resistance, there can be a significant voltage drop. Quote Link to comment
