Default 5 amp fuse in Carrier heat pump blows

I had to replace my circuit board due to it being fried. I determined
the reason it got fried was due to it having a 10 amp fuse installed
instead of a 5 amp. I labeled all the wires as I removed them from the
board just to make sure not to get the crossed in the reinstalling. Now
the 5amp fuse on the ICB in the air handler blows as soon as I apply
power. I have tried to ring the wires but I really do not know which
wires should ring to each other or if none should ring together at all.
Any one have any advice?


Fuses don't protect electronics, they protect wiring. Your electronics
will fry long before a fuse blows. The fuse may also be used to protect
traces on a circuit board. Either way, the fuse size is not the *cause*
of anything.
