Haunted House
Gottlieb, 1982I just got my haunted house back home and when I turn it on the speaker is crackling a lot but not changing when I touch it so I don't think it's a grounding issue, also d tilts and ball in play lamps stay on as well as the displays being messed up. Nothing when I push the start or reset buttons. All the fuses are good and most of the coils were replaced recently, let me know what's going on if anyone can help out.
Quoted from arpman:I would check all the electrical connections first. Look for corrosion or bad contact.
I agree. Especially since you just moved it.
I would start by checking the power supply, make sure you have +5v DC at the test point. Make sure the connection from the power supply to the MPU board is good. The displays can light up even if the MPU isnt getting 5v power.
Did it work before you moved it?
Quoted from blownfuse:Do NOT mess with the connectors with the power on, it can or will get worse.

System 80, not just a job, it's an adventure
I never do but disconnected and reconnected all of the harness and no improvement. I'll get some pics up later but there's been a lot of replaced parts, the mian fuse is gone and just has a wire nut on it . . . But I swapped it with the main from my BH and still no difference. BTW, my BH is working fully aside the upkicker but replaced the coil, transistor, diode, ect and now it's blowing out F17 each time. Showed switch 43 on test but not sure where to find it. Any help is appreciated.
