Yep. Hard for anyone to help if you give us so little info.

Then it would appear that diode is fine.

Thanks.
Fv seems to match.

Schotkeys do have lower barrier potentials than normal diodes. A typical
silicon diode has a barrier potential of between 0.6 and 0.7 volts;
schotkeys less than half that so it seems slightly low but probably still
good. You can always look up the datasheet for that particular diode and
see what the Vf should be just to be on the safe side.

Well I took it out of Circuit and now its reading
Forward .171
Reverse 1
Soo I guess its good.
Rats.

SR560 is a 5A schottky rectifier diode with 60V reverse bias capability

Normally you get the out-of-range symbol in reverse, many meters display
that as a "1" at the left and no other digits.

If those readings are made with the diode removed from the circuit,
it's definately bad. else probably bad.

When I tried casting out nines I made a hash of it.

1.7v one way round 0.17v the other shows it's shorting.

trying to fix AC/DC power plug.
I have a Diode that says:
GW327
SR560
I THINK this is a Schottkty Diode.
Setting meter to Diode test,
Im getting, 1.71 Forward and
Reverse .171.
Normally on diode I know you should get 1 on reverse
Are these readings allowable or is the Diode Bad.
Thanks.
