Title: Bally mpu board wiring and rectifier mounting plate
Post by: Klondike on July 20, 2017, 03:20:24 PM

Hi
Can someone take a pic of the top right hand connectors on the Bally Mpu board showing the wiring order as mine's all messed up? It's a '79 Future spa. I'm also chasing a rectifier mounting plate if anyone has one to sell.
Thanks.

Looks a bit messy ! Could you clean up the wires themselves, as it is hard to tell what colours they are from the photo ? You might be hard pressed to find a Future Spa owner, so have you got the schematics ? If not they can be downloaded from www.ipdb.org - If you still need a hand report back and I'll have a look at work.
