I own Hardbody and had the same exact issue sometime in June.

For me it was a dirty connector somewhere. Either at the flipper button or one of the switch connectors at the lower flipper, I can't remember which.

It was just that though, a bad connection. I didn't have to replace anything.

Have you checked the leaf switch at the flipper button?

I've had new eos switches that required a lite filing and then it worked. Perhaps try this on your second switch.

Yeah, I would think so. I wonder if it is the coil acting up for some reason.

Or as others have said, a short or bad connection from the lower switch to that flipper.

Mine did that exact same thing. For me it was the lower right flipper switches. I gave them a good sanding and the connection was fixed.

The tungsten contacts used for these switches are seriously hard metal and require heavy duty filing with a new (IE: SHARP) points file.

I suspect you haven't ripped into them hard enough. These are not like the gold flashed contacts in newer machines that don't carry large currents. Under no circumstances should these newer contacts EVER be filed.

One of those blades looks pretty bent? Perhaps the contacts are not mating cleanly because of the bend?

The problem is nothing to do with the EOS switch, you have an open circuit on the "hold" winding of the coil.

The EOS switch normally shorts the hold winding allowing maximum current through the thrust winding.
When the flipper reaches the end of stroke, the EOS switch opens adding the hold winding to the coil circuit to reduce current.
Because your hold winding is open circuit, the coil is collapsing causing the flipper to retract until the EOS switch makes contact again. This is then causing the machine gunning.

Carefully inspect the two very thin winding wires on the coil going to the middle lug and the lug with the two dark brown wires soldered, the thin wire might be broken at one of the lug.

With the game OFF:
Place a piece of paper between that EOS switch on the problem upper flipper so the switch isn't making contact.

Grab your multi-meter and put it on ohms/resistance mode. If your meter isn't auto-ranging, then set it to the 2000 ohm scale.

Measure the resistance between the left outer lug and the middle lug of the coil. Then measure the resistance between the right outer lug and the middle lug of the coil.

Report the two resistance readings.

If I'm not mistaken, your measurement on the hold winding looks like 6.08 Mega ohms. That's an open circuit. That winding should measure about 320 ohms.
The measurement on the thrust winding you got of 3.3 ohms is good.

Carefully move the thin wire windings leading to the lugs to see if either is broken from the lug.

Wow, the coil? I would not have suspected that.

Well done!

Glad you got it going!

Have a look if there's any damage to the thin winding wire/connection. They are usually repairable.
