strange. It should have more even to the GND, and the GND is 1M to the case.

[daveone23]

Are you saying if I measure ohms from the ground lead to case it should be 1m ohms? That low resistance tells me there is a leak to ground, right?

[morzh]

Well, in the sch you provided (there is something missing at the very bottom, but I think it is GND), the sole connection to the case shown is the 1M resistor R31, which is used to bring the case and the GND under the same potential.
Unless I am missing something.

Of course there is a cap across that R31. And it could be bad. Or, again, we are missing something.

[daveone23]

I guess I need to look at r31 and C7.

[morzh]

That too.
There might be other things.

[daveone23]

Interesting readings, r31 common ground to case bounced to 1meg on analog meter, r31 common to case bounced to 1meg. R31=1meg.  Across c7, which is common to case with a parallel resistor = 40k ohms steady.

[daveone23]

My resistance readings are not even close. Worried about pins 1 and 6. Even though they are off, the meter works on dc 50v and higher.

>>r31 common ground to case bounced to 1meg on analog meter, r31 common to case bounced to 1meg.

Would you re-read and correct?
This does not make sense.

[morzh]

Check all your caps. Even ceramics. I am not sure what is going on.

[morzh]

Just occurred to me: what if you have a power transformer leak? From a, say, secondary to the case. If it is bolted to teh case.
Not sure how to better check it.
