How do you know if the battery is charging. - Jet 3 Ultra Power Chair

If you have shorted the polarity of the battery, you have probably damaged a diode in the voltage regulator...You should be showing better than 13 volts DC at the battery terminals while the engine is running...Use a digital meter to check it.....If you unplug the harness coming from the engine to the Voltage regulator...You should be showing better than 50 volts AC at the engine harness while the engine is running...Be sure your meter is on AC setting when testing the stator harness...Also be careful doing this test as a possibility of electrical shock exist...Be careful not to short any terminals.........

have the batteries load tested first

Hi, If the battery does not charge properly. The battery in the unit maybe the problem. Replace it.
After a long time of use the battery will not hold a charge.anymore. Good luck.

Try another known good working battery and if it doesn't charge and hold the charge properly,

If that doesn't work, try another know good working ac adapter to see if it is actually charging the battery properly.

If that doesn't fix it then you know for sure at that point the motherboard is bad.

When the amp meter reads 0, then it is no longer drawing amps and is fully charged.

i hope this was helpful,

The 'ON' position is for charging OR jumping the car battery. Normally, you just hook the unit to the car battery to jump start it, then remove it and the car alternator will charge the car battery.

the power supply may not be delivering the necessary power to charge your battery.

Its ok. Um just leave the battery plugged into your laptop and the power cord plugged into the laptop as well and the laptop will charge it for you. If it won't, the battery is no good and get a new one but you don't need a external battery charger to charge your laptop battery.

have you tried your dads battery in your phone it sounds like the battery is dead if your charger works on your dads phone then you know it not the charger the chances are it is the battery it would only be the phone if it has been dropped or got wet if this hasnt happened then the problem is the battery if your dads battery is the same then try charging his batt through your phone that way you would know if it was phone or battery.

If you take the phone into any phone shop they will test the phone and battery for free for you they can try the battery and also try a new battery in your phone and they will tell you if it is phone or battery but from my experiance it is going to be the battery let me know how you get on ok
