I finally got my favourite machine from my childhood and would love to join the club. It was stored for 30 years (or so I was told) and they left the good ol Eveready batteries in it all those years! The playfields nice but the backglass needs sealing with some paint shrinkage. Cabinet's solid too. When I switched it on after doing all the checks the lights came on but that's all. Lots of learning to do but looking forward to bringing Firepower back to life.

Thanks for the comments guys. What a shame they left the batteries in. I wasn't sure if I should repair the boards or replace. I don't know anyone local but it's definitely missing the speech board which I might have to source from the US. I printed out lots of info but I couldn't find a manual online. Are all the parts for the Mpu and driver boards still available?

I was looking at that board. I think they're out of stock right now but that's probably what I'll do. What are your thoughts on the speech /sound combo board?

I love those sites. I pretty much used up all my printer ink on all the material on the blackknight site! Yes it is great to finally have a game with loads of available parts...even backglasses! Even though I just sealed mine and am going to touch up a few areas and hope for the best.

There was a little green fuzz on the battery holder terminals. I was going to stick the boards in the dishwasher...is that something people still do to get rid of any residual gunk?

Does anyone have a page showing what size playfield rubbers and where they go? If anyone has the actual manual that would be good.

Very helpful info, thanks Don.
At the moment when I switch the machine on, I just get static lights in the backbox and playfield.

Thanks. I got that instruction booklet with my game; but isn't there another manual for Firepower?

I managed to get the game to start but only after restoring factory settings and turning the game off and on. The game doesn't go into attract mode on startup automatically. Straight away the left kicker locked on. Initially, in the solenoid test it wasn't firing and I found a wire off the coil which I repaired.I also replaced the diode and now I'm thinking the problem might be on the driver board but I'm not sure.

I ended up sending all my boards away including the display one as I was having issues with the displays too. My hands shake too much to do any fine electronic work so I'd just make a mess of the boards if I did them myself.

I'm replacing the playfield rubbers and noticed this switch behind the stand ups. What does it do and is there a particular way to set up the rubber band...I didn't take notice when I removed the old ones.
Thanks .

I knew it was an early one as it's number 407056 but that's awesome that it might be a little bit special. I wonder what the story was?

Here's a few pics under the playfield Hhaase. It looks like a few pilot holes around that area.

My top right pop bumper locks on when I switch Firepower on and blows the solenoid fuse. I've replaced the diodes and the coils okay so would it be a transistor on the driver board? Can anyone pinpoint which transistor handles that pop bumper? Any help would be appreciated.

Thanks mate.

Turned out to be transistor Q6.

Great info regarding the pop bumper locking on, thanks. Are all the resistors the same throughout...the 1N4004 ? I didn't realise the third on the switch was a capacitor, lucky I hadn't changed it yet as I wasn't sure of the part number. Meanwhile, another glitch has reared its ugly head... where the ball goes into the left lock but isn't recognised and so doesn't release or lock properly. At the end of the game it releases the ball though. I've been using four balls just so I can have a game without the glass off

My Firepower isn't releasing the ball from the left kicker still. I replaced the transistor and the diode and the wires are securely attached to clean switches. It has the green wire with red stripe and I noticed that my unused switches for drop targets have the same wires. Could this have something to do with it not working?

Would someone mind taking a pic of the switch under the left kicker hole showing wiring and diode placement? Mine is all messed up. Thanks in advance

Thanks but I'm after the switch parallel to the playfield that gets activated when the ball rolls into the left hole.

This is the switch I mean. Apparently my switch is from a gottlieb??

Perfect, thanks.

Having problems with the top right pop bumper locking on. Is this 1n4004 diode facing the right way?

IMG_20200118_195025 (resized).jpg

Thanks. It still locks on when I remove 2J13 so more driver board problems. I sent all my boards away for repair but this issue keeps arising. I changed q5 &q6 and also ic8. Can you confirm my resistor, diode and capacitor in the pic are the right way round?

Is the + side of your capacitor facing down? From your pic it looks like my resistor is the wrong way round and I can't see your diode?

The first time the boards came back it was fine for a day or two then failed. I replaced the two transistors for the pop bumper and it came good. The second time I got the boards back it worked for weeks until it went out again with the locked bumper and this time no sound or speech. I replaced the processor chip on the soundboard to get that going and replaced the two ic's on the driver board but nothing. I had already replaced the diode on the switch stack. I also had a technician out who reckons the boards are just old and will keep stuffing up even though I spent close to $600 having all boards repaired and apparently 'bulletproofed'.

Okay I will, thanks. Hopefully the switch diode, cap and resistor are all in the right direction as well.

No luck after changing that diode and the two transistors.
Two other issues I wanted to ask about;
When the ball goes through the F lane the score and noise register but the letter doesn't register. When you lite other letters you can lane change to light the F and it will still award Fire and the multiplier when you lite all four.
The other issue I have is the power target in the middle when hit, lites the one to its left. The left target when hit will lite and register as will the one on the right but the middle will never register or light. I changed the diode on the middle target and the F lane.

The yellow wire attaches to the lower switch in an awkward way. Not sure if there's a tab missing from that switch.The different coloured wiring, I believe, relates to this being an early proto fp set up for drop targets.

I've sent all my boards away 3 times now and I've still got issues 6 months on. My sound goes out and then comes back on randomly and other times the sound and speech is slightly different to how it should be. Like one sound is missing or garbled. Good luck with yours...all I could think of was replacing some pins and the processor chip on the soundboard. That worked for me for a short time until something else went wrong.

I just got my boards repaired and now when I try and power up, the two top bumpers and the left slingshot lock on. Then the second fuse on the power board blows. Do I need to send the boards back again? I sent the driver and cpu board away because the game had the top right pop bumper locking on and now it's got more problems...
I also noticed that the switch below the power targets triggers 'tilt'. Any help would be appreciated.

Yes, the 40 pin m/f headers are new. Only the one pop bumper locked on; then when I got the boards repaired, other coils locked on. I had changed the diode on the pop bumper.
