ADDED ACCESSORIES
The Otis S-71 did not originally come with the following accessories. Various owners
have added them to my S-71.
EXTERNAL CHARGER INPUT (added)
The external-charger input is wired directly to the 36- volt connections to the battery
bank. The charger connector is a standard 30-ampere female connector used for 240VAC
electric clothes dryers. The ground terminal is not used. Any commercial 36-volt charger
may be used for charging the batteries. Mine is a Club-Car model 10470 “Solid State
Fully Automa tic” charger.
LIGHTS (added)
The front and rear lights use 12-volts from two of the 6-volt batteries as shown. This
wiring has a 5-ampere fuse for safety. An SPST toggle switch on the dash controls the
lights.
BATTERY STATE OF CHARGE METER (added)
This expanded voltmeter is widely available (in 2005) at golf cart shops for about $30.
This “fuel gauge” is connected to the positive 36-volt battery post. The negative lead
goes to the key switch so the meter only works when the key is ON. A 5-ampere fuse in
the negative lead protects the wiring.
