RJ - can you clarify? Do you mean that just bypassing the time delay would eliminate the problem, or that replacing the SCR on the card would eliminate it? 

Thanks,
Mike

I wouldn't do that temporary fix.  You may forget to wait some day.


It would only be for using it today to mow the lawn, since I'm expecting
to have card 1 fixed by next week, so I could put it back to normal.
 If I do switch to quickly, the result, I *think*, would be a big current
spike in the field coil, which would fry the reverse relay - although I
have put a 10 A fuse in that line where it connects to the relay, so
hopefully the fuse would blow instead of the relay.
 Would there be any other potential problem?

Mike
