Terminator 2 weak flippers.

Quoted from GRUMPY:
Clean the contacts of the new EOS switches, then adjust them so that there is more pressure holding them close but still have an 1/8 gap when flipper is in the up position.

I've had s similar problem on sopranos caused by.not enough pressure on Eos contacts when closed. Not sure on t2 -- are cab switches high voltage or just a switch trigger to a board?

T2 still has high voltage contacts

Ah -- op did those get replaced with new switches then?

That'd be the next thing I try to jumper out

Yeah -- it's sounding very much like an eos switch not having enough pressure on contacts (if normally closed) or burnt up cab switch contacts. Very unlikely the transistor, they usually just totally fail. Possibly bad electrical contact at a lug?

Check mechanical stuff first, is coil sleeve long enough to penetrate coil bracket (=plunger won't touch metal bracket). Also there must be a gap between flipper bushing, if you pull flipper upwards from playfield, there must be at least 1/8" gap.

Switched the power from the left to the right and it works! Joy! Only problem is now I am blowing out F101. Yikes! I am guessing I have something wrong with my Powerboard on this one. MM reads different power from the left and the right. Something is up. Any other thoughts before I send this board out for repair?

Can you explain more what you mean by "different power from the left and right"? What exactly are you measuring, the potential from positive lead to ground braid? What's it giving you for each side? (You are not measuring "power" with the multimeter btw, power is the product of voltage and current)

I'll go back and re-measure, give you more details. Here are some photos. If anyone notices anything strange let me know. Also, according to Vid's guide the diode side should be away from the coil stop, is that correct?

Simply switching from one coil to the other allowed the right flipper to work... well until it blew F101 that is.

Yes - lugs go opposite coil stop that's correct, keeps vibrations at coil stop a little farther away from solder joints.

When does the fuse blow? I'm assuming if you say it works but blows fuse that it works for a while, then blows? Does it blow when you hold the flipper up for a while or just random after you hit it a few times or...?

After about 3-4 pushes or if I hold up the flipper you can see it get red and then *pop*
Thanks for the help!

In that case sounds like the hold coil isn't engaging possibly, could the diode be reversed on the hold windings? I'm not familiar with t2 so I'm not sure how the Eos is setup up

Good point, that would explain why I am blowing a fuse on the second flipper, but not why the other wires for the right flipper don't drive the left flipper as the fuse tested ok.... maybe I should go back to the fuse/testing.

Your EOS switch is not connected correctly. It should connect to the Blue/Purple not Blue/Yellow. The other coil is correct.

Replace the EOS switches and the flipperbutton switches.
Always the first thing to do !

I have yet to do the FB Switches, but the EOS's are brand new.

Well that should hopefully solve the problem
