Re: (ET) Odd reverse behaviour



The hair puller on that set up is the connector itself. It starts to split open, making many poor and / or intermittent connections. I ended up soldering flying leads on mine, and buying connectors at RadioShack®. One of the neat things that poor connections at that card can give you is unexpected low field voltage in Reverse. That provides a ride that you will not soon forget !

8 speed CA. Hm. I would believe a problem with the card; I blew out a few doides awhile back and replaced them. Back to the drawing board. The question will be what went bad (as the shunt circuits are working)

What model is your E-20? Mine is an 8 speed CA model, and cruise is NOT locked out in Reverse.Reverse problems are usually found to exist on the card edge connector. Look there first.

Ok, this is a bit odd and needs to be fixed.

My E20 has a problem with reverse. If you go into reverse and press down on the pedal slowly you get into speed 1, but never higher than that (speeds 2,3,4 ignored). If you floor the pedal quickly you get into speed 3, then 2,1 as you let up. Go to zero, press the pedal normally and you only go to 1.

I know the E20 has a lockout in series with the FW resistors to lock out speeds 5-8 and the cruise control in reverse, but why no speeds other than 1 unless I floor it fast?

Odd. FWIW, I watched the relays, no difference. Forward works perfectly.
