K3 won't power up... ???

n4la

Hello.....
I was using my K3 this morning and suddenly it just shut off. I thought it may be the power supply ..... so I switched to another one.
when I hook the red/black DC power cord up to power supply .... the power supply won't turn on ...... but if I unhook the power cord, the power supply will work as it should. Both power supplies work fine with my little FT 857D. I checked the fuse on the back of the K3 to see if it had been tripped .... but all seems to be ok. When I turn the power supply on ... it will turn on for a spli second and go right back off.
Any suggestions on how to get the K3 to power up again ?
Thanks... N4LA / Todd

Todd,

Sounds like a dead short somewhere. Does the power supply lite up if you have the cord connected to it but not to the rig? If so, it's after the cord unless the power pole is shorting when you plug it into the rig.

If not, it's the cord.
