Thanks for the links! My marina just called this afternoon and it was wires 5 and 7 crossed! 1 hr labour and I'm back on the lake this weekend. My ski buddy who has a malibu winterized my boat and he says he must have crossed the plugs wires up! I will be labelling the leads and the cap so this doesn't happen again! I wish I would have had this info at the lake it would have saved me alot of grief!

Thanks to everyone for the great info!

Glad to hear it's all good. +++ to all of us who suggested timing but major props to LSM who suggested crossed plug wires. Nice work gentlemen!

Glad you got the problem resolved !!!! It usually ends up being something minor like that...

I hate you had the problem but I'm glad that fixed it. - and it was a cheap fix too..
