I did my fans last night and ran out of time, so I quickly wired them hot with 30 amp inline fuses. The temp gauge worked fine with this setup on the drive into town, but died on my way to lunch. It reads fine for the first 45 seconds then drops to 160, and this is with out the truck running or just turning the key on. I am going to wire in relays this after noon and later I am going to wire into the PCM. Has anyone had this problem? I am sure it will go away when I rewire, but I would like to know what caused it.

Thanks
Kevin

 

Not sure, I never came near the t-stat, sensors or gauge on my fan install. Did you tie into the t-stat sensor?

Nope, just ran from the fan to switch to power source, and fan to ground. weird

 

damn, must be some good fans to cool it like that. lol <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

After you finish the job I'd try to get the thing on an autotap to see exactly what's going on with the gauge. On a good day mine is only about 15 degrees off of the actual temp.

 

Rewired fans to the fuse box and gauge works fine now. I still don't understand what the deal was, but everything is fine now.

There are these things called multiplexes (I guess that it ties more than one system together) and (according to my car stereo buddy that fixed it for me) you can pop fuses and overload systems easily!

After I put my fans on, my A/C didn't work, truck would keep running after you turned the key off and took it all the way out(!) and an assortment of other little things...all because I blew a 10amp fuse!

Just make sure that you're not overloading any circuits!

 

Everything works fine now
