Lethal Weapon 3 Tripping Mains Power Off

[Luka]

Hey folks I hope I have come to the right place to hopefully get a Lethal Weapon 3 pinball table working again. Firstly it had a issue where when it launched the ball it would launch 2 instead of one (not in multiball mode just normal play) but after being on for 30 minutes or so it would stop that. Anyways the problem we have now is a few weeks back the pinball was on and the building was hit by a power surge and a few of our machines really didn't like it (Naomi cabs showed JVS errors suddenly) but the pinball seemed fine so we pressed the start button and went to launch the ball and it tripped out the building electrics! We reset the fuse box and tried again and pinball tripped it again which was weird. So we open the top/header box and looked at the fuses and them seemed OK besides one that looked blown but what we did was take every fuse out and checked it on a multi-meter which showed them all good besides the blown one. Also would the fuse being blown cause it to kill the buildings electrics that badly from a blown fuse, I always thought it just wouldn't not turn on or display a error.

EDIT: We have replaced the blown fuse but still get the same results

sounds like the line filter and vairistor ha packed up

Thanks for the reply Chris, is that something easy to find and replace?

Yes, where the mains plug connects at the rear of the machine - inside the machine follow the wires from the socket and they will go to the line filter first. However line filter faults normally trip the electrics as soon as the machine is switched on... rather than when the start button is pressed, so I suspect your fault lies elsewhere - probably what blew the fuse that you replaced.

I'll take a look inside and get some photos uploaded, are the line filter things simular to ones in arcade machines? Sorry to sound dumb but pinball tables are completely new to me and I have been mainly working with arcade machines for the last few months.

@Luka - if you can update your location then maybe there is someone around the corner that might be able to help....

Good idea matey, anyways we are based in Bridgwater down in Somerset which is the south west of the UK.

Is it tripping the house electrics due to a high current surge, or is it tripping due to an earth leakage fault? Do you have a separate earth leakage circuit breaker?

To be honest I don't know mate, the actual pinball table is in our arcade not at home and we have had the electrics done (needed to be done) just before we opened back in July.
