Troubleshooting:
If the unit does not operate, check all of the wiring connections to make sure they’re
both mechanically and electrically sound – specifically at the battery, and the motor.
A fully-charged lead acid battery in good condition at room temperature should read
12.65 volts. At 11.9 volts it is considered to be fully discharged and in need of charging.
When checking battery voltage, wait at least 1\2 hour after the charger has been turned
off before checking the battery’s voltage.
If the batteries aren’t being charged by the charger, check the output charger
fuse. Verify fuse is good with an ohmmeter, or close visual (ohm meter best).
Fuse is a 10Amp 250 Volt; GBD 10A. If it is good, check the battery’s state of
charge with a voltmeter. The charger must be connected to the battery in order
to read the output voltage of the battery charger. Depending on the state of
charge of the batteries, the voltage should be somewhere around 27 to 28 volts
dc.
If it is determined the batteries are dead, and need replaced, continue with the following
procedure.
Tools Required:
14mm wrench, or crescent wrench
Regular flat bladed screw driver
