Hope someone can help. I had a coil lock up, so i pretty much left my High Speed alone for a few years. Finally decided to get it up and running, called a local guy, he came and looked at it, pretty much said i need to replace the MPU. It had a burned transistor and another chip totally burned. As you well know you just can't go out and buy a system 11 replace board for a High Speed. So I did a little research here and sent the board off for replacement, it came back all testing fine.

I had clipped the wires to the bad coil, lower jet bumper, so that would not be an issue. Installed the board and crossed my fingers. Hit the power button and all was well. See happy smile. So know i just have the bad coil to deal with. I replace the coil and solder on the wires, power up. but the coil does not energize. HMMM Well crap

When i go through the test mode to switches edges and test the blades that should active the coil, they test fine, other than the coil never energizes.

I have about $400+ invested in getting it back running, and so close. It is playable, with out the lower jet bumper.

So I'm don't really know what to look at next.
