How to test a VB921

I've searched and seen it asked a couple of times, but could not find an answer.

Is there a way to test the VB921? Thanks. Brian

You can test it easily if you have a stimulator. Modify the stimulator as shown in the assembly manual.

Thanks woh. I think I forgot all about that part of the assembly because I am using the fuel pump relay to make sure I don't burn up the coil.

I had a bad vb921 that looked good on the stim. Use an ohm meter to check the resistance between the leads when on and off. My still switched but it leaked alot when it should have been off.
