OK guys, after following your suggestions on testing the diode I have found the following. The diode has the same resistance in either direction. On my very expensive harbor freight multi meter it tests 001 on the 200 scale. Using the diode testing feature, (Which I have never used before), the test shows the same number in each direction. Looks like I have a bad diode.
Since I felt that I would be throwing the diode the way, I cut open the yellow shrink wrap jacket and found that the red stripe on the jacket was on the same end as the stripe on the diode, so it looks like it was assembled correctly.
I don't want to repeat the mistakes I might have made when testing the contactor and causing harm to the diode. Is there any way of applying power to the diode that would kill it?
Thanks for all of the help. Rich.
