Testing Charger
Take off front cover of the mast and locate the back side of charger inlet. Connect the charger.
Led # 2 will shortly turn green and then go off. Led #1 will turn red to indicate the charger is in step 1 (Bulk
charging). Measure DC voltage on the plug. While charger is at step 1 the voltage shall be increasing slowly read-
ing about 26-29V DC. When charger goes green the voltage will drop below 27,4VDC.
If the charger immediately goes green on LED#2 and stays green the fuse is most likely broken or
the wires to batteries are not connected. Voltage at the plug will read 27,4-27,6V DC. If batteries and fuse are fine
and the voltage is NOT increasing at step 1 the charger must be replaced.
Note that the charger has a "memory" of the status of the batteries as long as it is connected to the plug. It shall be
turned off and disconnected from plug for at least 30 seconds to reset this memory and start a new charging cycle.
