Jinma 354 alternator charging output?

[DonRina]

Just wondering what my alternator should be putting out for voltage. I get 12.24 volts at 1500 rpm which seems low. My battery always seems to have trouble turning the motor over. The battery is new. Maybe the alternator or regulator are shot? Any troubleshooting guides for this? I did take apart all the electrical starting and charging circuit and cleaned everything. Grounds were cleaned as well.

Most alternators put out at least 14 volts. It has to be higher than the target voltage for the battery which is usually 12.5 to 13.

I would first check to make sure the belt isn't slipping. Then probably go for a new regulator

Do you have an ampmeter? Does it show that the battery is being charged?
