I know there are many replacements for the original GM 1513321 temp sending unit used thruout C1 & C2. And its hit and miss trying to find one that actually sends the correct signal to the temp gauge. I'm trying to find one now for my BB 66. Today I checked the 4 sending units I have and they all measure different resistance (at room temperature).
Does anyone know (or can measure) the resistance of a sender at 70-80F (room temperature) that actually reads correctly on the gauge between 180 & 210F? At least then I can walk around a swap meet with a multimeter and try to pick out one that might work properly. I don't understand why its so hard to make a repop with a proper thermistor. Bill
