so the upper left flipper on my 6803 Party Animal is weak at first, but holds strong. When I put my finger in front of the flipper bat, I can hold it down. When the bat is allowed to hold, it's strong and I can't force it down. So something is causing low power in the beginning of the flip.
The lower left flipper is strong. The coil switches on the lower left control the upper left flipper.
I'm going to replace the all of coil switches on both the lower left and upper left flippers.
The switch on the lower left coil is corroded.
I believe the corrosion to be the issue.
Anything else I should look for that would cause the low power on the initial flip on the upper flipper?
