That said with a multimeter connected voltage started at 6v and goes to 20v but the potentiometer looks like it's been replaced by a ten turn so it will allow you to go higher than it should. I connected a 10amp load and it indicated 10amps on the gauge. Sold as is, no actual testing completed. It does have some scuffs and scratches as seen in pictures. Given it's age, it's very likely that it'll need some level of service before it can be used with any real accuracy, so for this reason it is being sold as-is.
