Re: DT30 Charging system

Did you slow charge the battery before using it. Need to do that at least overnight.. To check the charging system connect a multimeter on DC volts across the battery and note the voltage. Start the motor and run at about 1K rpm. The voltage should indicate higher than the base voltage. At about 2K rpm you should see something in the order of 14+ volts.I have both an ameter and a voltmeter on my Suzuki rig but I usually reference the Voltmeter to check before I start up and once I am running.
The voltmeter is connected between the ignition "on" terminal on the switch and ground.
