Gauge panel resistance readings. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Due to the fact I had to replace my tachometer tonight, I have the instrument cluster on my 67 out of the truck. Does anyone know the resistance readings of the Amperage gauge, temperature gauge, and the gas gauge? I am not sure if any of these, especially the gas gauge are correct. Is there a source on this site that has those readings? Any help would be appreciated. Kerry

Kerry,

Here are some readings, (note left in the description is looking at the face).

Ammeter: Post to post .2 Ohms
Post to ground (either one) Open

Temperature gauge: Post to post 48.9 Ohms
Resistor 59.9 Ohms
Lower end of resistor to ground .1 Ohms
Upper end of resistor to ground 59.8
Left post to ground 72.7 Ohms
Right post to ground 121.6 Ohms

Gas gauge: Post to post 36.4 Ohms
Left post to ground 72.6 Ohms
Right post to ground 65.5 Ohms.
