embryon meltdown

forgot to ask but I was not careful with the GI circuit with orientation of holders especially the A1363's. The red wire may go to the top contact and further down the braid line its connected to the lower connector if you get my meaning. Could this be a problem

Also I have noticed down one GI path one end has say the red wire on the top contact, white on the lower and at the other end I have a red wire connected to the lower contact or the opposite way around.

Will either or both cause the F5 to heat up?

I am guessing red/orange on my loom is one type of connection and white/green another.

A1363 - should not really be an issue. But are there A2915 or A2916 in that same circuit ? That would cause problems.

Unplug J1 from the Rectifier board
Locate the two GI circuits. The colours will be

J1 - Pin 1 = GI BUS
J1 - Pin 4 = GI BUS
J1 - Pin 3 = GI Return
J1 - Pin 6 = GI Return

They will be paired off - so on the playfield there will be a colour denoting the GI BUS and the GI Return - easy to spot on the playfield. So by testing with a meter, you can find out which pair are shorted to Ground. Remember - GI Return is effectively Ground - So what you are looking at doing is a process of elimination with the GI BUS coloured wires - one of those is shorted to ground, and which ever is - that's the next part to figure out.

You can test with J1 inserted and the game off. Pins 3 and 6 will be shorted to ground. Pins 1 and 4 will not - so which is shorted to Ground ?

Update, may have it sorted. Found braid wires connected to a red and a white wire were crossing over each other and touching. Located near middle of playfield. Separated these and F5 hardly gets warm after 15 minutes of game play and being in idle mode. This could be the solution.

Now to staple braid in areas I think might cause problems in the future and some switch adjustments.

Thanks for your help Nino, you kept my head focused in the right direction. Oh also this torch you gave me came in handy. Not so much for lighting but as a stress release while looking for shorts. I pumped that baby like nobody's business. My forearms are bigger than Arnie's now

thanks mate, I have a ok stapler ha seems to do the job, but much appreciative of the offer

No dramas mate. I had the time to help out (wish I had more of that time for other issues).
