Title: 122-105 transformer issue
Post by: SPN on September 08, 2024, 04:08:27 AM

Hello 🤗

I’m afraid I burned the transformer on one of my slot machine when I was working on it, I got a short
Circuit on a cable that was connected directly to 1 and 9 on my 122-105 transformer that I wanted to remove, I think it was meant for a electronic coin entry or something since the wire was going to that area in the door..

I live in Norway so I use 220v on my machines..

Is there an easy good way to test if the transformer is dead and need to be replaced or can be fixed ?

Thanks

Update!

I disconnected the transformer and tried it in another machine and there it is working so the transformer is ok!

So now I have tracked all the wires from the fuses and finally I fond the problem!

The white wire that goes from the safety timer unit up to the transformer was burned right
off just before the connection that’s right below the transformer, it’s repaired and now it’s working again!

Surprising it didn’t blow a fuse.
You might want to verify the correct ratings of fuses are in the holders.
Many times people throw any old fuse in there and this is what happens.
