Hi guys. I neee some help on this one.
Got this jungle lord that dident start up.
I checked fuses ok.
Pressed gameroms in place and it started up after 25years on storage.

It locks 4 coils and keeps them energized. Im guessing an IC is shorted that controlls all those 4 coils? Or any other ideas? Dont know where to look

Which four coils specifically lock on?

#5 6 years ago

Usually fuse F2 blows on the power supply when coils are locking on. Check your fuses for the correct values. Something expensive might get cooked.

Fun game, with some wild action from those short pulse magna-saves.

These old Williams games commonly have bad solder joints on the header pins, and the connection between the CPU and Driver board can be troublesome.

So crazy. I unplugged boards and reseated all ics and it started up. Plaes great
But no sound.
