(ET) E15 goes forward/forward

["paul gilbertson" <paul gilbertson net>]

I did the dreaded "threw the ET in reverse while moving forward" and
burnt out the reverse relay. 

Now about 4 replacement relays from Keith later, I still can go only
forward no matter where the control is.  The relay accurately fires but
the ET just moves forward either way I move the speed control.  I have
verified that the reverse relay works. Numerous relays that I have tried
have had the same result. They all have worked in the speed relay
position and I watch it trigger.

So, now what should I check/do?

Missing reverse in Minnesota.
