I have a Cal Spa 2000, 1996 year model. I was testing my heater for voltage, and the probe fell out and hit a relay on the bottom(BIG SPARK!). Lost power to everything. replaced the sc-20 fuse, and had power there after that, but not to the relay. I traced the wire that it hit(white one) on the relay, and it went to common on the board. So I figured I will have to replace the board. I tried replacing the relay, but that had no effect, still no power. I know the board is a Balboa. the numbers on a lable on the board are as follows : S/N BC2000*61202032 P/N 50865.

I searched various sites for 50865, but could not find it. Is there a replacement board for this one, or a diffrent one?? I tried to post pictures but I was never able to load them on the site. Also checked the other fuses, and they are OK. Its 10 years old, so I figure a new board is due anyway. Any help is greatly appriciated.

are you sure the part number isn't 50805?
