Thanks very much for that guys.
Well, it's definitely 10A or it's definitely 16A! 10A means an output voltage of 20v AC, and 16A means an output voltage of 30v AC.
I'm getting 20v AC on full throttle which if correct would suggest I have the 10A system. However, if it's the 16A system then I...
I have an Intek 24hp that started to suffer from flat batteries. I checked the DC voltage from the regulator which was 0v. I also checked the AC voltage at full revs which was 20v.
I know I need a new regulator but wondered if the 20v AC was sufficient? The manual says it should be 28v AC
