I'm looking for a different power source for my Mini-Maxx... the underhood fuse that I am currently piggybacked on is a switched 12V source as per the instructions, but the problem is that it always "short cycles" the programmer when I start the truck because I have to first wait for the grid heater, and then when you finally twist the key all the way to start the truck, it kills the circuit and the Mini-Maxx reboots again. This doesn't seem like a big deal, but about every 3 or 4 key cycles the darn thing looses the pyro source and reverts back to the factory source setting, so I have to fiddle with it to properly ready my EGT's... Just a PITA that I would love to figure out how to avoid? Yes I can get out my test light and check each fuse, but I figured someone has already solved the problem and figured I'd ask before wasting 20 minutes of my time... Thanks for any tips!!

 

If you are having problems with the EGT it's probably about to fail, mine acted up to begin with then just quit. I ended up going with the H&S "universal" EGT and it's a much better set up than the original one, I also reused the original probe along with the new probe as it was still good.
