Stern Solenoid/Driver Board - RevC

<< < (11/11)

Sinbad79:
Spent the day up with Studley working on the MPU board.
We tested systematically, fixing problems we came across as we went but to no avail. Just couldnt get the board working, so after a day of trying, i decided to grab one of his spare Alltek MPU Boards.

I can't thank this guy enough for his afforts & troubles, a very friendly and helpful guy who wants to impart his knowledge to others - he even fed me lunch!

Thanks Damien!

Next - onto the solenoid board driver - some wierd AV voltages so will be replacing the large capacitors and any known bad transistors and working from there. This project has been a very good learning curve!
