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 1980 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
