The chair wont take a charge and ive bought 3 sets of batteries so it aint that

Charging circuit is damaged.

I had same problem. I found a Zip Tie had dug in the wires that only effected the charging not the controlling part. Till the Zip Tie dug in farther, till it cut another wire, preventing the chair to move. That's is when I discovered it. After finding this out, my old batteries were probably good. I just assumed it was their end of life

i take it this is a used chair,u just bought someone elses problem,sorry,begin by checking voltage of batterys,after they are charged,then see if if it powers on,if it doesnt,id ask for my money back,or u can hire a tech to look at it and give u a written report on what it will take to fix it

charger is no good or is not the correct charger for that chair suggestion have a dealer tech replace a original charger in chair,it should have a 3 yr warranty anyways

Locate the two wires from the circuit breaker attach one wire (black if marked) to the negative post of the rear battery and attach the other wire (red if marked) to the positive post of the front battery. Locate the two wires coming from the power module plug with a red and black wire. Attach the red wire to the rear battery positive post and the black wire to the front battery negative post. attach the joystick to the nine pin plug at the rear of the chair and turn it on. You should have power at the joystick and the chair should work. Disconnect the joystick put the shroud cover back on grease the seat post and reattach the seat then plug in the joystick and charger plug at the rear of the chair. Charge the batteries before use and charge them overnite for the next 20 days. If you use the chair daily charge your batteries everynite while you sleep unplug in the morning. If you don't use the chair daily charge at least once per week or after you use the chair. Always put the chair up fully charged if you are going to be out of the chair for an extended time the disconnect the batteries at the large plug going to the power module Hope this helps you

Lets solve this, one question at a time ....
First your batteries are not charging,This may be because of it siting for too long without a charge.The batteries may be so dead that your charger cannot reconize them. dont losse hope there are ways to check your batteries and charger with out spending alot of money on a tech coming over.
1) Unplug and remove your batteries from the chair
2) Find your self a charge that trickle charge
(Note: If you have a batterie charger ,trickle charge is the lowest set charge)
3) Trickle charge each batterie to about 50%
4) Install batteries back on to chair
5) Plug in chair charger
The chairs charger should come on ,and that right there tells you that you have a good charger!
The batteries that came with this chair are not bad and are considered ok to use .These type of batteries are what you call maintenance batteries ,which your always having to check if the leaking or need water.The gell type batteries are what they call non-maintenance.That you dont have to always look after but are more money.Thats why they recommend the gells so that the user doesn't have to work on there chair.

I hope that was helpful ,Happy Riding

Bad Charger or bad batteres that all it can be Hope this Helps

If the chair sets for several weeks the batteries will wear down to the point that they cannot be recharged. Have the batteries load tested and I bet that this will fix the problem.

the usb port needs to be replaced on the phone

is it charged?????

if no then charge it for 4hrs and see.

if it's still not working change the battery
