Hi, I have a Goldline Aqua Solar controller around 7 years old that keeps blowing its 2A slo blo fuse shutting the system down. I have checked the case, board and everything looking for any shorts, burned traces, bad caps, etc and I do not see anything obvious. Anyone know what may be causing this - anything common? Or what part of the system does the fuse protect - like could it be a bad actuator or something causing it or is it something on the board itself? Would like to fix this if at all possible before having to replace. Any ideas? Thanks!
