I have a Pool Pilot Digital which is giving me problems red blinking light with 0 volts and 0.2 amps checked water chemestry, perfect. salt at 3800ppm replaced cell two months ago sc-36. So i suspect the main power board. took cover off and alum gard to see only one of the two fans working. can this be the problem? also checked fuses all good. no burnt wire ends.The unit is six years old is that all i should get out of it? .If I need to replace where can i go to get a new digital power supply cheap.Thanks
