For those of you with Gauge problems, I may have your answer.
 

When I got the suburban, THe gauges were already in it. THe fuel gauge didn't work, and the temp gauge didn't work, even after changing the sender. I changed out the fuel float (as it was cracked). Now the fuel gauge read at about 1/4 tank full and went down according to fuel consumption. I did a search and didn't really see an answer anywhere. Then on a whim I tried something out. I pulled the resistors that are on the back of the gauges off another known good cluster. Using my multimeter I ohmed them out. The fuel gauge resistor ohmed at about 188 or so. the Temp resistor ohmed at 90. I pulled the resistors off my Suburban and the resistor on the fuel gauge was reading 88. The temp resistor would not ohm out at all, so it was bad (hence why it was pegged at Hot). So I put the 188 ohm resistor on the fuel gauge, and the 90 ohm resistor on the temp gauge, and wha-la! They both read correctly!! So if you are having issues with your temp gauge not reading correctly, or your fuel gauge not reading correctly, check the resistors, they could be backwards if they were put on wrong during installation or after cleaning. I hope this helps some!

Good to know

Good tip.. May save someone some money and/or aggravation.

Is that the correct ohms for these two guages 90 ohms and 188 ohms?
I guess one could look at the color coding if they're visible.

this is a good post for Krue's FAQ section!!

Nice tip, a lot of folks overlook those resistors and replace the gauge.
You can also change the resistors to work with different senders or to adjust the calibration of the gauges.

Thats a great tip! I checked my resistor back when I was having trouble with the gas gauge but I don't remember what it read. Thanks.

Any of our current vendors sell those new? I would be willing to buy at least two.
