NEED HELP WITH MP10

[Cujo#31]

Ok. So I got the infamous red/green flash on my driver the other day indicating a pump stall. Checked wet side, turning freely, checked dry side, turning freely. Tried power....red/green flash.
Then started the process of eliminaton. Swapped dry sides to drivers. Same error, same side. Switched everything back to original, swapped wet sides. Same error, same side. Figured I had it ruled out to faulty dry side. Took it apart to see if there was a cause.....nothing. so.....off to J&L today, $140.00 later I have my new dry side. Get it home. Hook everything up.....red/green flash. WTF?????? No matter which circuit board I hook to faulty side I get red/green but no fault code on other side. Even tried switching power supplies...nothing. CAN ANYONE HELP!!!!!!
