Hi

My newly recapped ARII pcb (sense modded since before) to Pole Position gives +5V fine when no game pcb is connected. When I plug in the game pcb the voltage drops to 0,8V though.

This didn't happen before the recap so I suspect that it's something fishy with the AR card. Are there any usual suspects/components that is usually the culprit in cases like this?

Thank you very much in advance

/Roger

Hmm, it was changed together with the recap, but perhaps I got a faulty one...

Will try to change it again, thank you very much for the tips :)

This is what my transistor looks like. Was included in a rebuild kit

I changed the 2N3055 to a new one & now it seems to work, thank you very much :D
 
It might have been bad or I did something wrong when installing it that made it go bad when powering up
