Hey everyone. I'm having an issue with my Stern PotC. The "raise sails" solenoid is locked on. This had happened before, and I found that Transistor Q5 was bad. Then I replaced Transistor Q5. All was good and running fine until I was playing a game, and Capacitor C6 failed. I just replaced that, now the the "raise sails" solenoid is locked on again. What is going on?

Summary of events:
Raise sail solenoid locked on
Transistor Q5 bad
Replace Transistor Q5
Play games, all good
Capacitor C6 blows
Replace Capacitor C6
Raise sails solenoid locked on again

Help!

Thanks Schwaggs. I just replaced the Q5 transistor with a brand new IRL540 transistor, and replaced diode D5 with a brand new 1N4004 diode. Hooked everything back up, turned on the machine, and no power to any solenoids. I thought what the heck. Then I look up, and Fuse F10 has blown (no red light).

So summary of events:
Replaced Q5 with an IRL540 transistor
Replaced D5 with a 1N4004 diode
Hook it all back up and turn on machine
Fuse F10 blows immediately on turn-on

Any thoughts?

Bump for the day crowd.

Thanks Schwaggs. I took your advice and realized that it was at the solenoid. Removed the ship, took it apart, and it appears the solenoid coil wire that leads to the lug had loosened. There was an oh so slight wear spot (not noticeable unless searching hard) where I could see copper. It appears it was grounding out by touching the metal frame of the ship. I also went through again and replaced the Q5 transistor, the D5 diode, and replaced fuse F10. Got everything hooked back up and played a game. All appears to be good. Thanks again for the help!
