345 keeps frying ignition boards!

[mifiveo]

I just registered here, and I need some expert help. I am on my second ignition board on my 345 and it just fried this one too. I had a disconnected ground after changing the water pump and the first board fried up. I reconnected the ground wire to the engine and ordered a new ignition board. I replaced it and it worked great for two hours and then it fried the new board as well. Several of the diodes and transistors are burned up. The ground is connected and is nice and clean.

I wish the **** fuses would have blown instead of burning up two **** boards. These things are $100. What do I do now? I'm out of options and ideas. What the HECK is causing this? Anyone ever see that movie "The Money Pit" well this 345 is starting to feel a lot like that. Any help is appreciated.

I have been too busy to look at this problem with the long weekend. I did take a quick look and noticed one of the wires was bent over almost touching the bolt in the picture. I don't know if it was maybe shorting out at this location? I would think the rubber boots on the terminals would prevent this but maybe not. I bent the connector back before the picture was taken. It was almost touching before. Anyone know if this could be what was frying my ignition board? I plan to do a thorough inspection of all wires and connections tomorrow.

Check you're ignition and make sure that you don't have two exposed wires touching, I help my dad work on a/c units and that is usually how the pc boards get fried on them, I see this kind of thing happen all the time.
