I’m new to the electronics kit building and I’ve screwed up! I built the K8023 kit and it worked fine (a pleasant surprise to me). While wiring my relays I accidently shorted the power (12v) to the ground terminal on the reciever board and fried something. What components might I have damaged? If it isn’t too bad I’ll just replace the bad components…if not I’ll chalk it all up as a learning experience and buy another kit.
Thanks, Bill
Check R15, D5, D6…
Thanks, I’ll try that.

Well, I finally bought some resistors and diodes so I could fix this mess (sort of ticked at myself for burning it up to begin with!) After taking a closer look at the board I discovered that one of the printed circuit connections had burnt…the one between the D1-D3 solder point and the connection SK1 (second solder point in ) which I had connected 12v negative to. I jumper the bad section but that didn’t work so I removed and replaced D1 and D3…it worked! 
Only one of the diodes tested bad but I’m not sure which one it was. Thank’s for your help…as I said before, I’m real new at this and feel good about learning something new. Now to try to hook it up without ruining anything else!

Well done! (except for the frying part:))
