Can anyone tell my what relay the pop bumpers go to? I have one switch controlling both pop bumpers, and the coil
that pulls in stays pulled in.
Thanx

There's a pop bumper relay that fires them both if either's switch is closed. Not sure the letter offhand, but if you check the pop bumper coils on the schematic it should show it

Check the eos switched at the bumpers. It is supposed to open at the end of the bumper stroke. My guess is it's staying closed, out of adjustment.

Thanx, I guess I have one coil that is not working, switches seem ok.
The swich(NO) that is made by the skirt and spoon, I am assuming that's what pulls the coil in.
What does the other switch(NC) at the end of coil stroke do? release the coil. The one coil that is pulling in is not releasing.
Thanx to all for help

The skirt and spoon NO switch activates the (B) Right & Left Pop Bumper relay.
The B relay holds until the NC EOS switch breaks its circuit.

Do both Pop bumpers work independently of each other?
When I hit the left skirt the right Pop pulls in and doesn't release.
Same thing when I hit the right skirt, the right Pop pulls in and doesn't release.
The left POP doesn't pull in at all. Do they both have to pull in and open the EOS switches to have them both release?
Both coils read 2 ohms,
Thanks

They both activate together

So if the both don't activate the one that does will not release because the unactive one is not
opening the NC EOS switch. So both EOS switches need to open?

Yes, the 2 end-of-stroke switches highlighted in this picture both have to open to make the Pop Bumper (B) relay release.

Thanx It seems relay B controls the pop bumpers and after cleaning the contacts the problem is solved(hopefully)
Relay would not let go.I have other issues Ill post later
