[ICOM] Dead short in Icom 735

[k4lxv at bellsouth.net]

Dave: you are going to need a schematic to trouble shoot this .Look at the inputs to all the voltage regulators following the 3 amp fuse. Next look at the outputs to see if any of those also show a short. Using a low ohmage Ohmmeter might also help show where the short circuit termnates and its cause. Good luck.
