Sttng backbox reconnected faults

[Jagspete]

So sold my sttng and buyer needed to remove backbox to get upstairs, it’s his first pin and I did advise it was a risky venture. He’s getting a load of ground faults and want to be able to point him to the right board? I helped him with the disconnection (Marked the connectors as well)and he took loads of photos and was confident about reconnection although I explained there would no doubt be problems! I’m going to send him a link to this.

Traced to ribbon cable , connected wrong way round at one end, however now flippers and ball launch have no power, so sent him to check fuses with help from manual.

It's been a long time but I am sure you don't need to take any ribbon cables off to take the head off .
As with any disconnection of any connectors ,check and check again it's so easy to get it wrong !

I had to do the same with mine to get it down a flight of stairs.

I just paid Martin from Go Pinball to plug everything back in and it was done in 10 mins.

I certainly don't remember disconnecting any ribbons though.

Just hope coils haven’t ‘stuck on’ or transistors burnt out.

Where is the new owner based ? He may need some help.

A couple of ribbons needed to be disconnected to free up the loom to thread it out( plus dmd ribbon) He’s found fuse F112 solenoid Secondary 7a blown, ordered replacement, hoping just down to that turned ribbon cable.... he’s down near Oxford

You lazy git, I found that part of the fun - turning it in for the 1st time knowing I could potentially make something go BANG (didn’t happen luckily)

Well if he’s stuck he can call me out. I do cover the oxford area.
Fingers crossed for him.

I'd probably fancy my chances of learning the nuances of quantum physics faster.

Thanks for responses, original issue was twisted ribbon cable which blew fuse f112. Replaced fuse and all go at warp factor 8.
