Thank you for the explanation Alfa Wheels. I will try again with the sport switch once I have charged the batteries and see if that makes any difference.
My model does not have reverse.
As for the Indicator plug, from your explanation does that mean I can just hook up this voltmeter to monitor battery voltage?
