Re: (ET) new relay in - now no reverse

Since the time delay is likely inoperative, just using the Reverse switch in the throttle eliminates more things to go wrong.I suspect your time delay isn't working, since you have experienced reversing relay issues. ----- Original Message ----- From: "Michael S Briggs" <msbriggs alberti unh edu>

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
