So I put a new set of rubber on HH and had machine off of course while doing this. I go to play it after I was done, and the 313 bulbs in cellar don't light up anymore. The gi lights in cellar work, and game plays fine. Its literally just the 313 bulbs. I've checked all connections, and don't see anything wrong. Where should I start?

I can't seem to find this switch. About where is it? Also, now after looking at all switches and connections, the game won't play. It just sits with pulsing zeros in display, and won't start a game now

I just did slam mod. It no longer pulses, and seems to start fine, but once you push the start button, the displays go blank, and the credits read 00. It shows credits available before I hit start

It's in the trough sitting

Ball doesn't fire out if trough when I push start. It does nothing

Sorry guys, I just can't find this u relay. Any pics available?

Also, I swapped out a new set of rottendog boards from another working machine. It still blanks out the digits and does nothing. Does this sound like a stuck switch? I eliminated the slam switch mod, so it must be something else

So I checked the u switch and others. It's still not starting. It cycles like its fine, then once I hit start, the digits all disappear. Before hitting start, now only 3 zeros appear in two display. Boards are all new BTW.

I checked slam switch and tilt. Should be good. Frustrating. All relays seem fine. Cleaned switches, reseated all connections. It's just not starting a game.

The u relay was referenced due to the original problem of the cellar lights not coming on. That has since been resolved. The problem is still game not starting. I ordered a new set of connector pins, and will update after those arrive
The mpu should be good, as its new, and does exact same problem original board was doing. It seems like a bad connection or switch somewhere.

Ok, so my boards worked in my BH, so those are good. I've repinned half the connectors in back box, waiting on pins to come so I can finish all connectors. All fuses check out, however I ordered new ones as well. I have new caps at the power supply. Ground wire to new driver board. What else can I look at? Game is fine in attract mode, and goes blank once start is pressed. Also checked relays, and tilt/slam. Any specific connections or switches to look at while I wait for connector pins and fuses in mail? I can't run switch test, as displays go blank once I hit test button. Help

It seems to be that way. Lol

Orange cap was just replaced. Cycles through in attract. No think or any movement when I hit start. I see one trough switch, where is the lane one you mentioned? I can't yet rule out connections as I still have a few left to do. I can't do diagnosis as machine doesn't do anything when pressing test button

Thank-you. Hopefully connectors show up soon so I can eliminate all board connections.

OK, I made progress. The credit switch was shorting out it seemed from one of the wires not connected well. So, now it starts a game but with a few issues still. The left flipper machine guns when I hold in the left flipper button. Then, the main playfield seems to have the sound of resetting every time a target on main is hit. Last, when the ball lands in vuk to upper playfield, the middle(cellar) vuk is firing instead of the one the ball is sitting on. I did one at a time when I changed connectors, but could something be crossed? The ball does fire out fine when it lands in that same middle vuk. I'll post my connector pics if anyone can see anything wrong. Thanks for all the help.

Here are the connectors I've done so far. I tried to find pics on internet of what they should be, but only found a couple. See anything wrong?

OK, so tonight I finished all edge connectors, and still had sound issues, and main playfield issues. I decided to swap my old original mpu in, and guess what, everything is working it seems. The left second flipper is still machine gunning though, and switches seem fine on it from what I can tell. I'm contacting rottendog now to get a new board or a refund. As for the flipper, what else should I try? I'm close to fixing this, I need this thing off my mind. Lol

Here is the second(upper one) flipper assembly. Seems fine to me. Not sure how to test anything on it. This is both with flipper open and closed

On my buddy's t2, we cut that capacitor on his left flipper because it was staying upright once game started. Any chance that capacitor in pic is a similar problem?

I finally got it all working. A broken wire on the credit switch was the booting issue. Changed all edge connectors, orange caps, new boards, new flipper coil, vuk coil, rubber, and cleaned all switches. It's working good now. Thanks for all the help everybody. This was really a learning experience that helped a novice understand better.

I have BH (my first pin) and had a volcano that I sold. Bh and HH are definitely keepers. They all just go great together, and are all so unique. I really do like the system 80's as long as they're reliable, which so far bh has been pretty good.
