Re: [Elecraft] KPA500 Will Not Start When Pushing the On Button
Unplug the AUX IO cable from the KPA500 and try powering it on. If the Power ON/OFF signal is held low it will prevent the KPA from powering on. It might be that you have connected the KPA to the new K3 with a straight-through cable, which will cause this problem. The KPA _will_ power on if the interlock actuator switch is loose, but it will not go into OP mode. - Jack B, W6FB > On Feb 17, 2015, at 5:11 AM, Amateur Radio Operator N5GE > wrote: > > This is a 240V Amp. > > When pushing the on button on my KPA500 the power will not come on. > > It worked very well until I moved it to another place on the OP Table. > and connected it to K3 #1055 after having #1055 brought up to the > latest version at Elecraft. > > I have checked the fuses and verified that the power cord is supplying > the proper voltage to the amp internally and externally . > > What is the most likely cause of failure to get power to the amp? > > Which components should be checked next? > > Thanks in advance, > > Amateur Radio Operator > N5GE > > I have been up to see the > Congress and they do not > seem to be able to do > anything except to eat > peanuts and chew tobacco, > while my army is starving. > > Robert E.

Cycle the power switch on the back of the amp. On 2/17/2015 6:11 AM, Amateur Radio Operator N5GE wrote: This is a 240V Amp. When pushing the on button on my KPA500 the power will not come on.

Tom, Open the top cover and check the interlock actuator. If that was loose it may have become dislodged when you moved the amp. See the KPA500 assembly manual page 42.

This is a 240V Amp. When pushing the on button on my KPA500 the power will not come on. It worked very well until I moved it to another place on the OP Table. and connected it to K3 #1055 after having #1055 brought up to the latest version at Elecraft. I have checked the fuses and verified that the power cord is supplying the proper voltage to the amp internally and externally . What is the most likely cause of failure to get power to the amp?

Thanks in advance, Amateur Radio Operator N5GE I have been up to see the Congress and they do not seem to be able to do anything except to eat peanuts and chew tobacco, while my army is starving.
