First startup ... Pls Help!

[mlineHK]

just  completed all the terminal checks and all readings are good according to the manual.   once I plug in the power cord to the extension cord with the switch of the socket switched off the wall socket fuse jumped.  all visuals soldering are solid and I wired the transformer at 219-225v configuration after measurement.  anyone can help?

How did your power supply test go? (Page 52)

[mlineHK]

says 223v

[mlineHK]

o damn it, I skipped that test. 

[mlineHK]

is there a way to redo the test properly now?

[mlineHK]

disconnecting 275 2 reds and 1 black , also disconnect 6.3v 1red and 1 black, should be able to redo the power supply test ?

[mlineHK]

same thing, once plugged in the wall socket fuse jumps.  at page 51 step.

[mlineHK]

just disconnected the entire pt11 board out and try again the voltage test.  same thing the wall socket fuse jumped.

[mlineHK]

just found out only if te switch is flipped to power side the wall socket fuse won't jump.  I have changed cable and rebuild the switch cable and what can be wrong ? can u check the photos?   thanks very much.

You have a dead short to ground at the 3 position terminal strip at the power transformer. re read those steps and correct that.

[mlineHK]

Tks so much good catch. I will redo it today. I have used the wrong 3 terminal plate instead of the 5 cut to 3.

[mlineHK]

tks for the time and input to answer.  all good now except the kreg A side reading is 1v instead of 10-12v.  b side is fine at 10v.  any though?

[Paul Birkeland]

IA, Breg, and OB are all OK on both sides but you have 1V at KregB? Those results are not probable.

[mlineHK]

Yes I have check twice. But I shall do it again tmr and post photo of each reading.

[Paul Birkeland]

It's incredibly unlikely to have 1V at a Kreg terminal and both Breg terminals reading correctly.
