Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Welcome to JUST ANSWER small engines, let me try to help you !! I don't know it all, but maybe together we can get you a satisfactory answer!
Do you have a voltmeter to check the battery voltage? Check battery, then check the output from the charger , by plugging it to wall socket and meter leads on the charger harnes. Do not plug to battery until after testing both. Then check the battery voltage while charger is on.
Two of the four terminal on the battery should have voltage. two will be posiitve, two will be negative. you have to find the two pair that go together . If there is no reading, is the harness connected at the battery or are they direct to the harness plug in? Should be no reason that battery voltage would not be reading.??
I see question is still open, did you find problem?
