Glad you got it running!
1. I had the same problem with mine, maybe not quite as bad. I
found I wasn't getting into top speed due to a bad capacitor on the control
board. On level ground be sure you here the contactors click in as you go thru
the ranges and note the speed increase with each. Also, as someone pointed out
to me, run it for a while in what should be top speed and check the big
resistors under the front hood. If they are warm or hot, the last contactor may
not be kicking in. I don't know how the field weakening circuits affect
power since my E12S doesn't have that.
2. Almost definately the reverse relay not kicking in. When
you start to go into reverse (pushing throttle to left) you should hear it click
in. If you look where the throttle goes thru the dash you can see the
microswitch lever that gets closed which, in turn, activates the relay. The
reverse relay (on mine anyway) is on the inside of the panel at the rear of the
front battery compartment at the top right (looking forward). Reverse relay
problems seem to be common - mine has a wire pulled loose. I woudl check each
wire connection - sometimes the spade lug terminals get loose or
corroded.
