Hey guys
my turn to ask a Q.
on an American made PBC I have parts labelled VR1, VR2 etc They are surface mounted look like and test like a diode. ~ 350k Ohms one way, many 10's MegOhms the other way.
other obvious diodes are labelled CR1 CR2 etc, which I am familiar with the "CR" designation
was wondering if the VR is a Zener Diode ??
I'm in the middle of doing some reverse engineering of the circuit in the hope of fixing a very common fault we get with these units that we have many dozens of in service around Australia. The manufacturing company isnt forthcoming with a cct diag not even a partial one of the part of the cct that is of interest.
cheers
Dave
