Possible Reason
The vehicle's charging system regulator
or ECU is faulty.
A battery charger of too high a Voltage
has been connected to the auxiliary

Potential Solution
Check the vehicle's charging
system Voltage.
Connect a battery charger
that meets the Voltage input
speci cations.
Connect a solar panel that
meets the Voltage input
speci cations.
Relocate the Charging Device
to a more suitable location.
Check the Charging Device
cooling ns for obstructions.
Return to vendor for testing.
Check and correct the
polarity immediately or
irreversable damage may
occur to the Charging Device.
