Motor does an endless search on start up. Get an error message that it cant find home....Figured this would be easy so I checked the 2 switches underneath and they both work fine....Get no other switch errors. when the motor is searching back and forth it goes fine and then slows down like its dead then comes back to life and runs great then slows down. Does this till I power off.

In test it says calibrating please wait but it goes back and forth forever. Was hoping this means motor is good but not sure...It actually works pretty well when your playing the game but want to get this fixed...

How long is forever? From what I remember it takes a few minutes, longer than I would expect, for the gun calibration to complete. You verified both home and mark switches work, was that by manual pressing them in switch test or actually seeing they work during the gun calibration? Watch both switches during gun calibration and ensure they are getting triggered. The mark switch may need adjustment if the cannon is not activating it towards the bottom of its path.

Elaborating on this a little, it's possible for the switches to work when you press them manually, but the cannon mechanism might not press them down quite far enough in order for them to be triggered, so they might need to be adjusted (or replaced) if this is the case.

Forever is like 5 min at game start and then in gun test it says please wait for 2-3 min

Thx. since I cant move cannon by hand how can i see a successful trigger when gun is rotating? hook up dmm and tone for cont. when triggered?

I know one switch is a rollover that the round gear roolls over. The other is a leg and the short rod activates it.

hooked up dmm...switches work fine...as soon as the rollover arm enters the rounded groove the switch goes out and when it travels just past the groove it activates the whole time...the other switch with the long arm activates as soon as it encounters the little metal activator shaft...

In that case just let the calibration run via the test menu for a while, at least 10 minutes if it needs it. That may solve the issue. If it consistently hits the home and mark switches it will pass. It goes through many cycles so be patient.

Even though it's fixed and no credit dot. Still feels like it takes forever once ball loads to travel to lowest target. Started ball search before I fired. Thought I read the connector harness for the cannon can cause issues. I think pinball fantasies sells replacement connector

If the entire assembly has never been rebuilt (including the motor gearbox) take it apart and clean it.
Very light silicon grease is applied to the cannon post where the the solenoid assembly sits after cleaning.
Carefully open the motor box and re lube the pinion gears if they are gunked up.
If the last part makes you feel uncomfortable, don't do it.
This would also be an excellent time to replace the cannon loom as this the #1 cause of home, targeting, and launch failures.
Ensure there is sufficient slack on the wire harness so it does not bind or drag by using appropriate zip ties.
Looms are less than $10-15.
