I'm back looking for direction to solving a few odd problems with my machine....

1: Spinning Flipper. This flipper has worked great until last week. Now it goes on and off intermittently. Where do I start to figure out what is causing this? I realize it's not always supposed to be spinning, but when it's supposed to be on it will just stop and then it may start up again.

2: Car Crush reset. The car crush doesn't always return to the reset position. I replaced the solenoid, but that didn't fix the problem. What else should I check to correct this problem?

3: Left UpKick. As the game warms up, the kick out seems to become weaker and will always drain down the middle between the flippers. I tried replacing the PCB DC Filter but it didn't correct the problem.

Could these problems be related in some way? Just looking for some pointers on where to begin in order to resolve them.

Thanks in advance for any help out there.

Thanks for the info latenite04! So after reviewing your info I was able to narrow down the spinning flipper issues. Realized that the ramps weren't engaging. Checked and verified that neither ramp had power. Found that I had a blown fuse. Replaced fuse and tested the solenoids and confirmed they weren't getting power. Played game and they worked for a short period time before blowing the fuse again. What is causing the fuse to blow? Is it something on the Driver board that has gone bad? Mosfets, transistors, bad that operate the ramps?

Also corrected the weak left upkicker problem. Found that someone had the solenoid installed upside down and wasn't lined up correctly. Turned solenoid around and problem resolved. Kicks out hard every time to the right flipper.

Still trying to trace down the reset issue for the car plunger. It stills works now and then.

Thanks. The connections are soldered on. I can disconnect to try and narrow down even more. Yes, I have the 1 amp slo-blow fuse in F25. I appreciate your help and I will continue to research. I think I may have one of the rods jamming on the left ramp solenoid. I will disconnect that one 1st and test it. A wiring diagram would be great and I appreciate it.
