If you are not into Yahoo groups, than the above URL in EVAlbums also shows
some pictures of the van as well. I am intrigued by the 4th contactor for
field weakening!? Could this extend the range more than the 30 miles
estimated for this vehicle? Right now I am still trying to figure out all
the cut wires and where they go?! Wish I had someone here in NJ who could
go over this vehicle with me that actually knows how it works!?

My 1977 CitiCar uses 3 contactors (two large & one small). As I
understand it the smaller one is for starting and slower speeds and one of
the larger ones for full speed (a whopping 35 MPH). The second larger one
is for reverse when I flip the switch on the dash.
My 1981 Comuta-Van only uses the first two as it is equipped with a 3
speed (clutch less) standard transmission. You can see some pictures of
the van setup on Yahoo at:

Subject: [EVDL] early no controllers
When I was working for Clark fork Lifts in the late 60s they didnt have
controllers as we have today, They used a set of Caps, High voltage
rectifiers and Xfrmers , The Xfmers /caps could go as high as 300 volts
on a 48 volt battery system, there was 4 large contactors , one was
reversing, one was for field weakening , They had what was a very
rudimentary "controller" only about 5 or 6 resistors a few diodes and
some small caps , this went to the "gas peddle" the large Recs could
handle over 1,000 amps . The earliest electric fork lift I worked on was
from the early 40s, It had a "gear shift" lever that hit 3 different
resistors, "large" for different speeds, and one reversing contactor,,
simple and it was still in use way back when I had to rebuild the
motor,,,, brushes and clean the Com + springs , thats all it needed
