You have a dead short somewhere. You need some electrical knowledge and a digital multimeter for testing. Take all the covers off. Look for wiring that has rubbed through and touching or melted. Disconnect one of the motors and replace the fuse. If it still blows, reconnect that one and disconnect the other motor. If one motor doesn't blow and the other does, you know you have a faulty motor. If neither stop the issue, then you move up to the controller and look up there. With a meter you can check for shorts within the motors, as well as grounds.
Or just take it to a Service Centre and have it repaired and serviced properly.

Jet 3 Ultra www.pridemobility.com. 3 ... If the circuit trips, allow your power chair to "rest" for approximately one minute. ... thermal fuse on each lead.
Chances are you batteries are beyond their usable life and need replacement -OR- you have a disconnect between either battery and the chair. Please check to make sure the circuit breaker isn't popped, all the fuses under the shrink-wrap on the positive terminals are good and that the battery connectors are seated properly. If the batteries each measure 12-14 volts at the battery post while the chair is plugged in and either drop below 10volts when unplugged then your batteries need replacing.
amy why did you not keep the batteries charged? even new batteries have to be charged before use. Now plug in the charger and look at the meter with the charger plugged in the meter will show some reading around 4-5 amps. Let the charger work overnight when you get up in the morning fully charged the meter will read zero. Turn on the chair and all the battery lights should be lit. If after charging over night you are still getting one red light then you blew 170.00 and no amount of charging will bring them back. Sorry I wish I had better news. If you replace the batteries charge fully before use and then use the chair some each day and charge nightly for 20 days this will break in the batteries and get them operating at 100%. If you then only use the chair sometimes always put it up fully charged and charge at least once a week If you use the chair for that day charge overnight and it will be ready to use again when you need it. If you are going to leave the chair unattended for 6 months then fully charge the batteries and disconect them from the chair until you need it again New batteries every 6 months can get expensive Hope this helps you
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.
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
It sounds like a battery problem more than anything. If it were a fuse, the chair would not move at all. When batteries are stored, they need to be kept charged by charging every couple of week or so (ideally). There may be other problems causing this, such as a short somewhere or a problem with one of the motors/brakes/electronic componets draining the batteries, but I feel this is unlikely given what you have described. I would have the batteries checked at a dealer with a proper battery tester. Preferably have the charger checked at the same time. We use a specific battery/charger tester in our shop that is connected to a computer and will give a graph of the battery/charger condition. This way there is no arguments as to whether the batteries or charger is faulty. Hope this has helped.
If the battery is dead I would have the batteries load tested. Let it charge 12-14 hours. To operate the chair push the power button and push the joystick in the direction that you want to go.
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.
