[ICOM] IC756pro3 cable

[Lawrence Young]

Peter, please check the reflector archives for past reported instances of this problem. There have been instances of resistave power connectors and resistive fuse holders and fuses. It is wise, to check these first.

Hi on National Field Day we were using my PRO3 and after about 6 hours operating it died. We measured the volts at the rig end of the power cable and it read 13.8 volts, so we presumed the rig was at fault. We then fetched a IC746 and plugged it into the same cable, but it didn't power up. We thought it must be wired differently, so we connected it with it's own cable, now ok. We now checked out the pro3 cable and found the positive lead had a resistance of 180 ohms! one of our members said he had had a similar problem, he unplugged the inline fuse, reconnected it and the resistance disappeared and the rig functioned ok for the rest of the contest. The fuse contacts were perfectly clean just as the day it was made.
I see they have changed the inline fuses to a spade type on the IC7600.
Has anyone had this problem?
