To Next PageTo Next PageWhat to do if Curtis Control Unit shows overvoltage?
If the Curtis Control Unit indicates an overvoltage condition, it's likely because the battery voltage has exceeded its limit, which is typically (Nominal Voltage * 1.25) + 5 V. The suggested solution is to wait for the battery voltage to return to its normal range for more than 1 second.
