[TenTec] ps

[EDWARD CRAWFORD]

Normally the power switch on a Corsair is not even connected to the 12 volt 
leads, so you could turn the switch on and off all day and it won't do a 
thing unless it is connected to a Ten-Tec supply. In fact the 4 wire Ten-Tec 
supplies won't even turn on unless it is connected to the radio or the two 
center pins or wires are jumpered because the switch in the rig completed 
the circuit. Sounds like your rig has been modded to switch the power from 
the front panel. Maybe the switch he put in is heavy enough to carry the 
current load. As Mike said, the original switch was meant to handle only the 
low amperage AC current.

In my mind and from what I have learned from listening to discussions on 
this reflector is it is safer to switch the power from the Airpax breaker 
AFTER the supply has been turned on and the voltage is stabilized. And as 
you said, you don't want switch the supply off and have the lingering 
voltages as the supply discharges. The breaker is instant on and off.

I have not owned any of the later Ten-Tec rigs thus far ( Anyone have a 
Jupiter for sale? ) so I can't speak for the Omni V, but I believe the 
switch in those is able to handle the DC current. Someone else will need to 
answer that one for sure.

Later. 73. Ed/w4wvw
