wiring help

[pastiche]

Can someone tell me which wire on which connector works the lights on the three top poppers on Game Show?
thanks.......

J9 I think as they're part of the GI.

If not, try J13.

that is what I thought, but I cant work out which wire it is! there are 4 going into it....

So frustrating!! I have spent the whole morning trying to work out why these lights are out. I have changed the connector, reseated it countless times, taken the board out and checked the solder joints and all to no avail.
Does anyone have any ideas???

Thanks Carl,
Now I know which wires to look at I will strip it all down again and have another go.
I really appreciate your help..... thanks again.

Try checking that the bulbs are the correct ones! Once, I spent ages trying to get some flashers working in a game and eventually found that someone had put the wrong bulbs in (12v ones rather than 5v ones) even though they looked the same...!

Good thought, but they were working perfectly until yesterday!!

The lights on my taxi topper wouldn't work. Turned out to be dry solder on a lamp PCB on the back of the lamp board in the back box. Is game show system 11? If so sounds probable

Thanks Gaz, that's got to be worth a look......

So frustrating! Today I took the circuit board out and re-soldered the joints. I fitted a brand new connector and double checked the wiring. Put it all back together and the lights are still out. I don't know what to check next! Anyone have any ideas?

Did you try the board on the back of the lamp board?

could be a transistor I had that with gi

Any idea which transistor I should be looking at?

No have you need to have a look in the manual and trace it back

Never had transistor issue with GI ...are transistors even in the GI equation ????, I know triacs are but think they are rarely the issue. In my experience GI probs are almost always cracked joints, broken trace, burned connectors etc.

Ha ur right changed the transistor but later on found it was a broken track. Ignor me I've had no sleep

Try continuity testing the wires to and from the lights to the driver board.
