Everything works except.............

Just fired off my jeep last night after replacing a cracked head, carb rebuild, new gas tank, installed new EZ wire harness and a bunch of other little repairs and stuff. Everything worked great except the temp gauge does not work.

It did not work before I did all the work either. I was hoping that the new sensor and wiring would fix it but it did not. My jeep has on of those instument panels where everthing is in one cluster. I replaced it a couple of years ago. I put my trouble light on the sensor with the motor hot and running and it sends a signal of a dull blinking light. I think that is normal. Under the dash at the gauge I get the dull blinking light on one post and a bright blinking light on the post that gets power from the panel. I think this is right so does it sound like my gauge is bad ? And if so is there any way to replace those or do I have to buy a whole new gauge cluster ?..................Thanks

 

You can buy the individual gauges.
Here is a link to board member that tells you more about the gauge and how to check it.

ground the sending unit wire and see if the needle will move
with power on of course

 

Which side of the sending wire should I ground? The sending unit side or the gauge side ?

 

take the wire off of the sending unit on the engine
momentarily ground it on the block or a ground wire
then check to see if the needle moves

 

Ok, I got it. I will try it tonight. And if the needle does not move than does that mean the gauge is bad.................?

 

check ebay, they have a few different gauge replacements for temp and fuel that fit into the factory cluster so you won't have to buy a whole new speedometer gauge which runs a little over a $100 the replacements are around $25 hope that helps and good luck
