K3 build/KPA3 update - can someone measure for me...?

[Dick Dickinson]

I get about 3.6K across the input Anderson Power Poles of my early, but up
to date K3/100.

Hi All, getting prepped for ARRL DX next weekend and so I decided to

do the KPA3 update on my old K3 (#476). It involves replacing some

pins between the RF board and the KPA3 module to prevent melting.

 

I did the update and it went reasonably well. The last check is to

measure resistance across the 12V terminals to make sure its not a

dead short. The documentation says it should be over 2000 ohms, but I

measure open circuit. Can someone check for me what they see across

12V terminals on a regular working K3?

 

This is probably a pretty stupid question but since I didn't build

this K3 I'm not sure what to expect.

 

Thanks much,
