On my Ultra Jet 3 th power lights keep flashing?

Question edited for clarity.

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.

Flashing lights on a controller are showing you a trouble code. To find out what the code means, count the blinking LEDs.

A flashing lite is an indicator of a fault condition. Is it steady or flashing?

Do all of the speed lights flash at the same time or do they ripple from left to right? If they ripple from left to right the chair is in lock mode and you can use the unlock procedures from my tips to unlock. If they are all flashing at the same time you have an internal joystick problem and the joystick needs to be replaced Hope this helps

Its sounds like a bad connection problem,make sure all connections are good and tight.Check this web site for more help http://www.pgdt.com/scenter/diagnostics/diagvsi.html

 

Good luck

hold joystick back, press on button, move joystick forward, then let go.

Do they flash in series? Like ten flashes then a pause then ten flashes?
