Hi valentin 201
I have owned my own business for 3 years and have been working on scooters and powerchairs for 15 years. . In the future give as much info about the scooter as possible.
1. load test the batteries even if you think they are good, check anyway. Sometimes even new batteries won't hold a charge.
2. Your charger on the powerchair must have enough volts to open the charger inhibitor. That is, the charger won't even start up if your batteries are low. Both batteries need to have at least 20-22 vdc.
3. Some chargers have a 3amp fuse check that and repace if needed.
4. With a multi meter set on dc200 check your batteries. Red on one battery and black on the other. Check to see what you get for voltage. If no voltage reverse the lead wire to the other posts. Once you get a reading of 20+ volts watch the meter and plug in the charger, it should increase the volts on the meter. if not the charger is bad, replace. Charger should be 24-31 volts to be a good charger.)
I suspect the battery. Take the battery out and take it somewhere that they can do a "load test" on the battery. It's never good to just let a battery sit. When you let the battery sit without a "smart charger" on it, the charge bleeds down and the plates in the battery start to deterioate. Then, when you try to get it back by charging, you find that one or two cells are bad. The the bad cells will also prevent the votage from a jump starter from going through as well. Check the battery first, if it's 3 to 4 years old, it probably needs replacing anyway. Most motorcycle batteries don't last much longer than that unless they are premium grade batteries.
Well PawPaw could be 2 things First one would be the batteries. If they are older 2 years or so then I would replace them and then check the charger to make sure it is putting out the correct voltage. If you have a voltmeter set it to 200 vdc and plug the leads into the charger port located under the front of the joystick use the 2 outer holes of the port and with the charger plugged in you should be reading 27-30 volts. If you are getting just the battery voltage then the charger is bad. If you are getting 27-30 volts then the batteries are bad Hope this helps
Hixx the batteries are too low to light up the joystick and no amount of charging will bring them back. Sorry you will have to get new batteries. You will need 2 U1 batteries. Hope this helps
You'll have to get to the battery terminals while they're charging, and then you can measure the charger voltage, if any (around 12 v).
It sounds like your charger is bad, and you can order one from this site: http://www.monsterscooterparts.com/jet3ultra.html
Good luck, and hope this helps you.
Hi. A voltage of 34 volts is way to high. Most chargers are limited to about 28.5 volts. You will quickly dry out your batteries at 34 volts. I would say your charger is very faulty.
You have probably already destroyed your batteries at that charge rate.
Are the batteries new or a couple of years old.
I serviced a machine last year, that, according to the owner, had been through 6 sets of batteries in 4 years. His charger had the same problem as yours.
Good luck. Neil.
Hi. This could be caused by a few different faults. Some batteries when old, can have a good voltage reading but are unable to supply the amps to drive the machine. Connect a volt-meter to the machine and try and drive it. If the voltage drops right down, then the batteries will be at fault.
Could also be loose battery terminals, or faulty battery lead in-line connectors.
If you suspect your batteries get a serviceman to do a constant current test, and see how the batteries perform.
I had a customer that had been through 6 sets of batteries in 4 years. When he finally asked us for help, we found that his charger was faulty, and overcharging his batteries.
Get a serviceman to record your charger over a complete charging cycle with a data logger, and make sure that your charger is operating corectly.
Do you make long trips in your machine, and how often do you recharge the batteries.
Most batteries are designed with a certain number of "charge cycles". If you drain your batteries by 75%, you will only get a small number of "charge cycles". If you only drain your batteries by 25%, you will get 100's of charge cycles.
Good luck. Neil.
Its showing you the voltage out put for the charger if all power lights are lit and the chager is pluged in if batteries show only 2vlts then they are no good and the will not charge up thats why amp meter is on 0
