Need Help...Gas Gauge Ohms??? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

ryan68 · 08-13-2002, 10:17 PM

Does anyone know how many ohms our gas gauges are set to run at? I got a newer rear mounted Blazer tank and the gas gauge registers above full and the tank is between 5/8 and 3/4 full. I think it is 90 ohms, but I am not sure. Any help is appreciated.

I hate electrical!!!

All GM guages (since the mid-50's) have been set to max or min at zero or 90 ohms. Depending on if oil, temp, or fuel, they go either way from hi to lo.

On GM sending units, an empty tank should read as zero ohms, a full tank should read as 90 ohms (half a tank is 45 ohms). don't quote me on this...
