Found the problem
It was the relay.
Don't know why OD 2nd worked perfectly and 3/4 did not- can only assume the
3/4 ciruit was drawing more current but have no idea why
Works fine with the new relay
Thanks for all of the suggestions

and take a test ride. If it shows that the relay drops out when the OD does,
you know it's an electrical issue. Then change the connection so you can see
the lockout switch at work. Again, if it drops out when the OD does, you've
found your culprit.

would drop out for no apparent reason (although it was much more random) and
it turned out that the quick connect to the solenoid was very slightly loose.
Not loose enough to fall off, but loose enough to sometimes lose contact. So,
if the above test does show the relay is not being grounded through the
lockout switch, the next test might be to remove the tunnel and repeat the
experiment with the meter connected directly to the terminals on the switch.
