Thanks for the suggestion Buzzp,
It is most definately a zener diode according to the silk screen on the board.
I currently don't have access to a scope at the moment,
but I do have a decent Fluke 88 dvom although a bit dated, with many functions including min/max, rpm and duty cycle.
where...
Thanks for the info.
Sadly, this is part of an ignition system
and I get no voltage readings at all with the
unit powered up.
I imagine that the only time I would get a reading
is when the ignition fires.
my guess is that I would only have milliseconds
to take a measurement.
any suggestions ...
well, thats the problem, it's unreadable. ( I have pulled both of them off the board)
I do have access to a known good board though, can you
outline the measurements I need to take?
thanks.

Hello,
I've got a circut board with what appears
to be a bad zener diode that needs replacing.
is there a way to identify what the diode is or
what a suitable replacement would be?
here is a picture that will hopefully help.
