K3 - ERR 12V???

[Craig WØLV]

I was running WPX RTTY contest using abt 80W and it had ran for over an hour with no problems.  I have done it many times and the PA temp stayed around 50....  All of the sudden I received the ERR 12V.  I was watching the PA temp and it was staying around 45 to 49C.  The rig was running 3 bars on ALC, so was not overdriving the PA. Output was abt 80W.

I went into the Config menu and turned the PA off and then back on and it still does not show up in the display menu to monitor PA temp.  I have power cycled the rig and power supply a number of times and no luck???

Any Suggestions?  All I can get out of it is 12 W now and the PA is cool.  Cold air out of the back of the rig.  The Voltage from the power supply is 13.9V and I have a solid connection to the PS.  I cannot even get it to display the PA temp at all now even when I go into the Config menu and make sure it is turned on.  PA is set to NOR in Config menu.

Thanks
Craig WØLV

Craig,

Did you do as suggested in the manual list of error messages?  Check the
circuit breaker first.

Hey  Don

Thanks for the input.  The rig will poser on and only TX at 12W.  Is there a seperate breaker for th ePA?

Craig,

Yes, on the back near the fans.   See page 4 of the K2 Owner's Manual -
the identifier labeled "38" in that diagram.

Thanks guys for all of the input.  This is an older K3 serial 1085.  I have done some of the mods to it, but still more to do.

I have not had a chance to get the rig apart yet.  I did look at the breaker and it is OK.  The fans are stuck on High and I have not had a chance to do anything else.

Did all you said and the rig ran for a while and the same thing happened, also saw and 80C det temp on the PA and it was not that hot.  Cool air from the fans.

Have you examined pins 21 through 26 of J67/P67?
