It appears to be an issue with the reversing relay. When mine quit working I looked for a 36V relay but couldn't find one so I used a 24V heavy duty relay with a dropping resistor in series with the coil and it has worked great ever since. I have an E-15, but I'm guessing the reverse relay is very similar. You might also want to verify that the switch controlling the relay is good – mine has a small arm that is depressed by the speed control lever when you put it in reverse.

Subject: (ET) Help, reverse missing?
I was using my E12 with a 36" snowblower to clear our driveway this afternoon. I had about 10sqft left to clear and reverse stopped working.
All the forward speeds worked fine. There was plenty of charge. I could hear what sounded like a relay clunking when I moved the lever to the reverse. But no motion, and the fuel guage/usage meters didn't move.
So I kept going from off to reverse, off to reverse until I got it to move backwards. Coincidently one of the chains had fallen off the rear tire. So I backed it into the garage and put the chain on. I was going to just put it away but I tested reverse a couple of times in the garage and it seemed to work. So I went back out. As soon as I needed reverse it wouldn't work again.
This time I kept flicking the switch until it went into reverse and parked it in the garage.
Once it was in the garage I put the gear into neutral and tested.
Forward speeds work
Reverse doesn't (mostly)
How do I fix this, or where do I begin my search?
