Testing a OHC

Is there anyway that I can test a OHC before I install it? Can I just put the gray/yellow onto a constant power wire and see if it will power up?

you'll probably want to also hook up the temperature sensor as well, so you can make sure the temp circuitry is performing correctly.

All I wanted to see was if the display lights up, which it didn't. I guess I just got screwed over 40 bucks.

you need to ground it too before you think that its not going to work...and it should work just fine even if it was out of a totally trash rig. I got mine out of a really messed up rig and mine worked just fine...I just hooked up all the wires before I cut anything...then hooked it up in the air and it worked so i then mounted it...I would hook all the wires up and then plug it in the try it again!!!!!!!

Any luck on the OHC? Sucks big time if you got screwed.

Nope, Bob sent me a link that one of the resistors might be disconnected from the board, but that might be a little over my head for replacing. I guess I'll just have to find a really busted up one to take the brain from.
