Yellow light

[december45]

Cart is a 95 48 volt A9528-445415
the yellow light is on for 20 seconds, then off, then on, then off, then on for 20 seconds, and it repeats this over and over.
Can you tell me what is up or is there some legend or key to know what the light blinking means?
thanks

The battery warning light will not illuminate if the charge is 90% or more complete. The onboard computer
will retain in memory the amount of charge needed to replenish the batteries and will complete
the charge during the next charge cycle.
• When the charger DC cord is unplugged during a charge cycle, the battery warning light will illuminate
and remain illuminated for 10 seconds if the charge is less than 90% complete but the vehicle has
enough power for 60 minutes of operation. This will alert the fleet operator that the vehicle may be
used, but that it must be charged to completion as soon as possible.
• The battery warning light will repeatedly illuminate for 10 seconds, at 4 second intervals, if the charger
times out at 16 hours and the batteries are not sufficiently charged. This indicates an abnormal charge
cycle. The charger and batteries should be checked by your Club Car distributor/dealer.
• The battery warning light will repeatedly illuminate for 10 seconds, at 4 second intervals, during a
charge cycle (with the DC plug still connected) if AC power to the charger is interrupted. The light will
go out when AC power is restored.
• When paired with version 3.0 or later onboard computers, the battery warning light will flash quickly,
after inserting the DC plug, indicating the charger’s voltage suppressor has failed closed.
