Quoted from davebart5:I need some help or advice regarding some final issues I'm trying to fix with my HH. I've spent a lot of time getting my HH project cleaned up and now just have this final hurdle to overcome to be officially finished and playing games.
FYI - I have a Pascal PI-80 installed in this game.
First, everything was working (lights, game boots up, sound, pops, flippers, kicking targets, VUK, bank resets, etc.) except for the main PF right side extra ball hole coil wouldn't fire to push the ball out of the hole. I replaced that coil and the transistor there, but haven't been able to see if that is fixed due to a current issue I will describe below.
Before I could see if that extra ball coil is now working, I was testing targets and pops by hitting them with a ball, and my kicking target #2 randomly fired rapidly if hit, then the pop bumper above it would randomly fire rapidly if target #2 was touched and on one of those rapid succession fires of the target #2 it locked on and I seen smoke come up from under there. Target #2's coil was unusually hot for a while after and eventually had to be replaced because the sleeve melted and wouldn't allow the plunger to lower. I've since replaced that coil.
Since then, none of the pops, kicking targets, upkickers, flippers, etc. will not work at all. But, Bank resets, free game knocker, coin door coil, etc. all seem to work.
I've checked all fuses (F1-F15) and nearly all coils test well for good resistance. No wires seem to be disconnected.
I did have a pin inside my A3-J4 connector that was loose and when pushed out of the connector, looked to be broken. Pictures of that below. I will replacing that pin tonight.
I ran the coil test on the pascal and here is what happened... Other coils not listed below do fire upon the test.
Coil 2: error 2
Coil 12: Nothing happens when I hit test, no error displayed and no physical coil activity
Coil 13 pnp: Nothing happens when I hit test, no error displayed and no physical coil activity
Coil 15 pnp: Nothing happens when I hit test, no error displayed and no physical coil activity
Coil 16 pnp: Nothing happens when I hit test, no error displayed and no physical coil activity
I did find this article with what seems to be a similar problem. Does anyone have any suggestions on what could be wrong here? http://newsgroups.derkeiler.com/Archive/Rec/rec.games.pinball/2009-01/msg15776.html
Also, I asked Pascal about the problem and he recommended I check the game over and tilt relays. The 24VDC coils power is fed thru them. But, I'm not really sure how to test those and currently researching how to review those parts.
Sorry, I'm a newbie, but totally in love with my HH despite this headache!!!!
Thank you to anyone who can help here.
Hello, You sound like you were having the same issue I recently started having. Everything was working fine, then all the sudden most of the solenoids don't work. The bank resets, free game knocker, coin door coil, ball kicker (starting of game) and a few others do, but flippers/upkickers/some drop targets (mostly the bottom field) no longer work.
I've read through this but not seeing what you found to resolve it?
Thanks!
