Need help to repair two phase 400 amps

Go to bed, no reason to start that conversation this late, I'm goin to bed too....Nite!
 
That's so funny !!! I knew when I said Goodern ... I was asking for it !!!! Hello Lee !!!!!
 
Hello, going to renumber them one thru sixteen and test them in the diode mode. Please disregard previous readings. Be back after dinner and renumbering . Thanks
 
NOTE 1 THRU 8 ARE RIGHT CHANNEL ON #2 I SAW A 087 AND ON #8 A 502 ON THE DRIVE. .

Red on the base and black on emitter, give me 1 thru 16 on that....

That's odd # 8 changed? I had to be me and fat fingers.

That's why the readings are not making sense. The 910's are a Darlington transistor that have internal resistors. They will not measure like other Bi-Polar junction transistors.


OK, now red on base, black on collector, 1 thru 16. Your meter may not have enough current to turn on a Darlington but we can surmise a few things. Let's finish the tests.....I have enough outputs to replace all those 910's so don't worry about it....

Ok hold on.
 
We are still in diode test mode on the meter correct?
