INTRODUCTION:
The Fuel Gauge is designed to monitor and display the state of charge on motive power
(deep cycle) batteries.
SOM E APPLICATIONS:
Golf cars, pallet trucks, forklifts, personnel carriers, scissor lifts, floor scrubbers, EV’s,
bass boats.
INSTALLATION:
CAUTION: Always wear protective eye shields and clothing when working with
batteries. Batteries contain acids which can cause bodily harm. Do not
put wrenches or other metal objects across the battery terminal or
battery top. Arcing or explosion of the battery can result. Do not wear
jewelry when working around batteries. Arcing can cause sever burns.
Locate a place to mount the gauge. Mark the two mounting tab holes on the surface to be
mounted. Use a 1/8" drill. Use a 3/8" drill bit to pass all the wires through so that the gauge
mounts flush.. Be sure hole is bur free. Use sheet metal or appropriate screws to mount.
Attach red wire of meter to +battery . Black wire to - battery. Ideally, the wires need to go
directly to the battery. If this is not possible, use leads from studs, terminals or any other
contact points as close to the battery as possible. The meter must see battery voltage all the
time, connect before switches, contactors or anything else.
The fuel gauge may be connected with the key switch so that it will illuminate only when
switch is turned on. Connect the blue wire to a positive wire at the key switch so that when
it is turned on, power is applied to the blue wire. NOTE: If you do not want to use the key
switch feature, you must connect the blue wire to the red wire.
OPERATION:
When connected for the first time, the gauge will read static battery voltage. The bars will
light in increments as the battery is charged or discharged giving you an accurate reading
of your battery’s capacity all the time. When the battery is being discharged you will notice
a secondary ghost light bar operating in the background that will give you an indication
of how much energy you are using. The last bar of the primary light bar will flash at 1.75
volts per cell. The battery should not be discharged beyond this point, and should be
recharged as soon as is possible. Never charge a hot battery, let it cool down first. The last
LED bar will also flash at a static voltage of 2 volts per cell.
