As for mounting a plate over the reed switches, maybe try regular old steel first and see if it does the job.

Perhaps this problem is made worse because that pop bumper coil is mounted facing the drop bank, instead of the pop bumper's frame. Or would that not really make much difference?

Guess it depends on how close the switches actually are to not being activated vs. activated by the pop coil. Is the magnetism totally overwhelming them, or is it just enough to always close them.

Here's a dumb magnetism question - would putting magnetic shielding around the pop coil, even just a tin can, affect it's stroke power in any way? None, some, negligible? Like, you know, could it suck up some of the magnetism that woulda gone to the solenoid?

As for the metal strip possibly shorting anything, how about sandwiching it between two strips of wide mylar clear shipping tape first, then trim off most of the edges of the tape so it's sealed beyond the edges. Sort of laminatin' it. Maybe two more layers of tape, but the stuff is pretty damn tough. Then use the foam tape or whatever you're using to apply it. No worry about shorting or wire rubbing or size/positioning of the strip.

Quoted from Chuck_Sherman:

I have installed these on both a Flash and a Blackout. No issues.
I see that not everyone has the issue, was wondering if flipping the magnet over (changing N/S poles) would make a difference. was thinking the coil and the magnet may be amplifying the magnetic field[quoted image]

Maybe not having problems in general but for this one bumper in Gorgar, looks to be a common issue reading above.

As for the superglue coming loose on the magnets - are you guys roughing up the surface of the magnet and the area on the target first before gluing?

Quoted from oldschoolbob:

I haven't tried it yet but I wonder if a piece of metal flashing would do the same.
Any home construction going on in your area? Look around their building site for some scraps (1 inch X 4 inches)

I suggested that too, I don't have a Gorgar to test it on. I did once, but it was when Gorgar was only about 5 years old so the horseshoe switches were still pretty fresh.

Quoted from EmptyH:

This is my fix. It is a piece of soup can. I did bend the edges to make it less sharp and wrapped in duct tape. Basically, a rectangle. It has been working flawlessly for about the last 2 weeks.[quoted image]

I suggested trying a plain old steel panel but yeah it's probably hit and miss as suggested. Change the dimensions of the plate or the exact position/distance between the sensors and the pop coil, or make the plate a little curved or basically flat, might not work 100%. Whereas the mumetal sounds sure-fire.
