Reistor's
 

Does anybody have a link to the gauge resistors on the 67-72 trucks? Why the different colors on them?
Do these resistor interchange with outher gauges? I would think so.
Anybody know for sure?:chevy:

Andy I read an article on the gauge resistors and according to them the senders have certain dead spots in their resistance to heat to ground relationships. The sender will have a spot where the coolant heat has to rise quite a bit to effect any movement in the gauge needle.
To smooth that out, the engineers calibrated the resistors to the senders and the gauges and I assume the colors identify the resistance values.

one of our members, Tom TBone has done quite a bit of experimenting on the gauges and resistors and he may know more about the subject also he has a stock of resistors and he repairs gauges and clusters.

Here's a thread by him on fuel gauges so you can PM on the subject.

Thanks Vett,
Yea I was messing with the ramp truck gauges the other week and got the temp gauge working again. I had swapped it over to a tach cluster I had bought and the temp gauge never worked so I did some looking and found what I think was a gas resistor on the temp gauge. I swapped it with another temp gauge I had and checked it per your Ohms readings. it all checked good so I reinstalled and it's working.
That got me thinking about the resistor's. Thanks I PM'ed TBONE1964.:chevy:

I will send you a PM Andy,

Thanks Tom.

Always enjoy learning from the pro's!

I sent you a couple of link's that say they have the resistors.:chevy:
