I have made resistance checks at U12 with another multimeter (cheaper
one, the first one was a FLUKE 175 ) and I get more than 2 kohms,
forward and reverse polarity.

I have made some investigation: The fluke uses 7 V to make resistance
measuremens, and the cheaper one uses 0.6 V, so that could explain the
diference. What do you think?, Do you think that I sould worry about
the resistance checks or continue doing the Initial Power On Check?



Thanks

 Ramiro.
