T2 was working fine when I picked it up but parts were utterly destroyed throughout. Bought full complete flipper assembly's from pinball life (https://www.pinballlife.com/index.php?p=product&id=717) as well as new drop target assembly, complete stand-up targets set, lamp sockets, flipper leaf switches, ball launcher assembly and coil, cherry switch in gutter. It had 30 coils in it before but i now replaced them with 29s. Hooked everything all up as it should be and left flipper immediately blows fuse upon hitting the flipper button. Checked 101 and 102 fuses and replaced both just for kicks with the required 2.5 slowblows. Left flipper still blows immediately upon hitting the button and right flipper blows fuse when holding button down. Trigger on gun also does not operate right when in "shoot the hk mode" but works fine all other times. It won't fire until way after it's pressed. Right flipper also sometimes can be activated during non play when hitting the flipper button. Again, all this stuff was fine before, besides the right flipper being activated when hitting the button on non use, that was happening before and thought this would solve it. Ive exhausted all forms of wiring and common sense.

Again, everything worked fine before swapping parts. All wiring is exactly the same as before. I will check voltages and post back. I wouldn't put electronics to go bad Willy nilly so it could be an IC or relay went bad after i fired it backup from sitting for a couple months dead. Could also be a bad flipper coil they sent me, have had that happen on new things too many times to not rule that out.

I think I figured it out...just have to pick up some diodes. I think I fried the diodes on the one flipper when I first wired these up and is why the left flipper is dead and blows immediately. Still issue with right flipper when held down blowing fuse. Thinking it might be gapped wrong? Early T2s were shipped with 29s and many still use them, 30s were later used due to prevent excessive bumper and plastic damage overtime.

Quoted from pinmike:

29's are stronger than 30's..The lower the number the stronger the coil will be.The correct voltage should be +.50v and anything over that will cause fuses to blow.

Correct, thats what I was saying they started with 29's but later switched to 30's due to prevent excessive playfield part wear since the 29's were higher power.
