Re: (ET) E-20 Switching to Reverse While Moving Forward

["Raymon R. Ellis" <raymon10 comcast net>]

I have received comments from two members who reported they have 
experienced
no problems from switching to reverse from forward using the Alltrax
controller. My wiring may be different from theirs. One of them has the 
dual
pot setup which I tried to copy. But actually I am not sure exactly how the
switching works but I do not plan to use the quick reverse again. My main
motor jerked back so hard I came up off the seat enough to open the seat
switch. When I cut open the 10 amp switch today to witness the effects the
inside was black and the small points were melted. Now Harold Zimmerman 
told
me yesterday that the replacement switch was the original Micro Switch
brand. I have a mass of wires connecting the two 5K pots in my setup to the
controller. I do not know how to measure the amperes that may have been
generated at the switching but enough current flowed to burn up the
replacement seat switch. For better long term service I will practice 
coming
to a stop on my E-20 and I will add a 10amp fuse in line. Thanks.

I have fried a number of the little foward/revese relays in my E-15 
over the years by pulling the throttle lever into reverse while 
rolling forward (original equipment).  I have learned the hard way to 
come to an absolute complete halt before changing direction!  I 
believe I read somewhere that it was perfectly safe to shift the 
Alltrax from fast forward to fast reverse while rolling along at top 
speed.  It will ramp down and then back up without the big bang.  I'd 
love to have someone else tell me it worked for them before I do it!
