I was want to know if there is a way to test the ecm. I have a 12 volt draw on the battery with the ecm plugged in with the key on the off position if I unplug this the draw goes away. The bike also has no spark. Any help would be appreciated. And thank you in advanced.
I have tested everything that I can. The only thing I can see is there is a 12volt draw with the key off and when I unplug the ecm the draw goes away. So I'm thinking there is a short. What do you guys think.
I pulled the cover off there was no water inside of it nor does it look like there ever was some of the MOSFETs look a little discolored but nothing is defantly smoked. With the stator unplugged it still has a draw so I really think its fried.
I did a amperage test there is a 0.0 draw with the key off and it does not change with the ecm unplugged or plugged in. But there is a 11.75 volt draw with no amps. What the hell is going on here. I have no spark but everything else seems to work as far as I can tell.
OK I'll see if I can find what wires belongs to the pick up coil and see if I can ohm it out. If it does not pan out I will pull the side cover and flywheel off to have a look. Thank you I will let you know more on Friday my next day off these 12 hours shifts make it hard to get shop work done lol
Well after replacing some of the gm weather pack conecters and was ready to buy a cdi box I put it all back together and I have spark. I'm not sure why but none the less the bike runs great I took it for a 30 mile ride today and managed to find a couple of coyote to shoot in the process. Thanks for all the help guys.
