Need Help - Universal Double $$$ Nutty Jackpot

[colorado]

Hello,
I recently bought a Universal Double $$$ Nutty Jackpot. I have been doing some minor repairs
And clean up to it prior to bringing it in the house. Replaced a couple of bulbbed switches (cash out, Spin, bulbbed switches etc.)
Replaced power cord. Anyway, all was working okay.

Then I smelled the burnt electrical smell and saw a small amount of smoke come from a wiring harness hole at the main board.

I quick unplugged the machine. Removed the main board and routed all of the wires that were in the main board box to the outside.
(Just to be sure there wasn't a wire causing a short)

Now when I power up the machine, the first two reels spin as usual, and the third real locks up.
Another time I will power up and a coin trap door on the front door will engage and the reels will all start to make a humming noise.
If I manually turn the reels they will start to spin and won't stop.
Does it sound like the machine is shot. - - I hope not, I really like this machine.

I have photos if that will help...
Thank you very much for any help you can offer.
