Yes, it was the J5, 3 pin connector point on the RF board near the front center.
Ribbon cable is connected. I will check the AUX DC connector and start voltage tracing.

Allan, Was that J5, the 3 pin connector point (no header is normally installed there) on the RF Board near the front center (near the control board)? If you did everything correctly, it should have no effect on the K2 power-up condition. If you wired to some other place than the 3 pin J5, remove what you added and try to discover what the error is. It may have been something that inadvertently happened, and not at all associated with your additions - in that case, voltage measurements are in order. You may have had a pin pushed back on the AUX DC connector from the KPA100, and it is no longer making contact with P3 on the RF Board - insert the crimp pins into the housing correctly if you find that to be the problem. Is the KPA100 ribbon cable properly attached to the control board? These are but a few starter questions. 73, Don W3FPR Allan Bacon wrote: > K2 4670 with 100W and all options was working fine. > > > > Per the recommendation of Microham, I added a speaker jack from J5 to a > stereo plug on the back of the case and now the unit will not power up on > the KPA-100 > > > > When I plug in power to the low power jack, the unit is OK, but will not go > to high power. > > > > Any ideas? > > > > Thanks, > > 73, > > Allan Bacon > > W6GBG > > > > _______________________________________________ > Elecraft mailing list > Post to: [email protected] > You must be a subscriber to post to the list. > Subscriber Info (Addr.
