My mpv 5 turns on and horn works but wont move

last time i looked horn was on the lower front cross panel under the radiator.....BUT has been known to be above rather than under.....

Check the freewheel levers located in the front of the chair

From past experience, more than likely the carbon tips on the rubber keypad that make the contact on the circuit board may be degraded to the point that they no longer make contact.

It sounds like the power chair may have been sitting for a while; if so, the gel inside the batteries has probably solidified and they will no longer take a charge. Try replacing the batteries (u1, 12 volt, 33 amps) and see if that does the trick.

two levers in front by feet pull all the way up

If the horn won't work, the batteries are dead. If the charger is showing green lights, most likely the gel inside the batteries has gone solid from the chair being stored for a while. Replace both batteries with type U1, 24v, 33 amps and see if that will clear the problem. The fuses are regular automotive type fuses.

You need a new horn.

one of the motors is bad or has bad connection. try raising the chair so the drive wheels are off the ground (free-wheel) turn power on, push joystick forward and watch for drive wheels to turn. the one that wont indicates a bad motor or connection.

try to boost it with a good battery. if it starts,
replace the battery. watch your connections. don't reverse the booster cables.

i have a similar problem with a MPV 2001. After about a 1/2 sec from turning the key on, the horn will beep and the flasher go on, can will turn over, but it won't start. any ideas?
