I just bought a jet3 ultra and it looks new, but battery is dead. How long should I let it charge up? I have the power cord. Do you have it sit in it to make it go? How do I get it to go?

I suggest that you start with determining the condition of your batteries and work outwards from there. Dead batteries just don't want to take a charge. Test your batteries with a meter before you start part swapping. The internal charger is only about 4 amps so it will take many hours to charge a 24volt system.

You definitely need new batteries. There are 2 size U-1 batteries in the chair that will last between 1.5 and 2 years. Get the deep cycle sealed gel lead acid batteries, preferably AGM. Hope this helps.

Lets make sure the all battery terminals have the correct cable ,heres a web sit that you can go on to double check.http://www.pridemobility.com/pdf/Owners_Manuals/US_Jazzy/US_Jet_3_Ultra_om.pdf

Page 40 shows a diagram that covers it all.

Next after confirming that everything is connected correct,plug the chair in like if you where going to charge it,

I want you to check your ammeter if the needle moves to the center of the gage your charging if not you may have a bad charger.

Good luck hope i was helpful

To find out if your battery charger is working on your jet3 .
First thing you do is make sure its plugged in
Second locate your meter next to the plug on your chair
Third when plugging in the cord make sure your meter moves to the center of the meter.

If this works congrats your charger is working.

Unplug the joystick cable under the seat remove the seat if on a post lift handle on right side under seat and lift seat off post if not look for release levers behind front seat post and seat will rotate backwards to give you access to the batteriesdisconnect battery cables and install as on old batteries to new ones and reinstall Hope this helps

I think you are right with your diagnosis but the short could be literally anywhere so very hard to help with this issue. Sorry.

ron, if your batteries have ever gone dead or amps has gotten below norm, then the batteries will never hold a charge again. replace batteries.

I have a Jiffy Jet3 . the problem is when I charge the batteries
the light indicator just blinks but chair doesnt run.
I just put new batteries and still doesnt run,,,thanks J.J.F.

If you have access to a voltmeter,put it on your battery then plug in the charger; if the voltage rises that will tell you that your charger is working.
