JAZZY 1113 AFTER CHARGING 10 HOURS SHOWS ALL LIGHTS, THEN AFTER AN HOUR OF USE IT SHOWS 1 RED BLINKING. BATTERIES ARE ABOUT 1 YEAR, IT READS 26 VOLTS AT THE PINS ON CONTROLLER. ANY SUGGESTIONS?

The MK batteries are far superior to Interstate batteries overall.
You can load test the batteries to see if they are working properly with a load tester. Your can test the charger output to the batteries with a digital voltmeter connected to the batteries with the charger plugged in. These 2 tests take less than 10 minutes and can be done at a local auto or scooter shop for nominal expense.
Make sure the charger and battery connections are tight and free of corrosion. On the VSI of the Jazzy 1113 there is a notorious problem with 8 pin connector and 3 pin molex at the back. You can clean these connectors but a complete electrical rebuild of the pins and receptacles is sometimes required if significant corrosion has set in. Try spraying electrical cleaner and use green Scotchbrite to clean the metal tabs on the 8 pin connector. Make sure the 3 pin molex sits in the receptacle and is making good contact.
Hope this helps.

Have the joystick controller tested. Make sure the cable is fully seated in the chair connector.

7 year old batteries are too old. They will never charge fully. Replace both batteries at the same time.

my chair jazzy 1113 ats won't move.all the lights are flashing and the batteries are fully charged why are they flasng

huntin you might not get a reading at the plug to the batteries because if its not connected to a load the charger might operate until it senses a load. a better way to check would be to plug the charger into the outlet and take your meter set it to 200 volts dc and plug it into the two outter holes of the chager port located under the front of the joystick. you should get 27-30 volts dc with the charger plugged in. when you unplug the charger you will be reading the battery voltage. After charging overnite you should be reading 26-30 volts dc if you aren't getting that voltage replace the batteries Hope this helps

Pride has a problem with a battery cable that will draw down the batteries like you say just sitting there and I'm not sure if it is with the Jazzy 1113. I would contact Pride @ 1-800-800-8586 ask for Jazzy Tech support and explain your problem. They should be able to tell you more specifically what the problem could be. I still think the batteries can be a cause of your problem but the Jazzy folks can help Hope this helps

After charging overnite get a digital voltmeter set it to 200 volts dc and plug the leads into the 2 outter holes in the charger port located under the front of the joystick. If the charger works properly you should read 26-27 volts on the meter. If you are reading 24 volts or less then have the charger checked it should be putting out 27-30 volts or so. I would also have the tech check the batteries under load and check the wiring harness from the joystick to your controller. Hope this helps

Check this website to find the type of controller your scooter has. The number of blinking lights will give you an idea as to the the problem is. You may need to reset the system after replacing the batteries. Check your manual for troubleshooting diagnostic codes.

Good luck!

John Do the red lights blink or steady? this indication on the joystick usually means low batteries. Now this could be caused by bad batteries or a bad charger. On the jazzy if you have an on-board charger the light on the charger will come on green when the batteries are fully charged. If you can look under the rear of the chair you will see the charger and can tell if the light is green with the charger still plugged in after charging overnite. If the light is not lit then you probably have a bad charger. If you have a digital volt meter put it on dc volts 200 volt scale and plug the leads into the two outter charger port holes located under the front of the joystick. Your battery level should read 24-26 volts after charging all nite and with the charger plugged in up to 30 volts if there is no change in the voltage from charger plugged in and not plugged in then the charger is bad. You can then look to purchase an off-board charger that plugs into the joystick charger port to charge your batteries. If your battery readings are lower than 21 volts even after trying the new charger then you will have to replace the batteries. You might try to find someone in the local area that has an off-board charger you could borrow to see if you can get the batteries to charge. This will help you find out if the batteries need replacing. Hope this helps

Most likely your charge isn't charging properly. You need a multimeter to test the voltage at the joystick. In the 3-pin femal connector measure the voltage across the two horizontal terminals. It should read about 24 volts. Now plug it into the charger and see if the voltage increases, if not, charger needs to be replaced. You can get one that plugs into the joystick on ebay a lot cheaper than going to the mfgr. about $50.00 or so. Even if the lights are blinking, it may not be putting out sufficient voltage to bring the batteries up.
