Hi All,

I had an issue with my tilt lock some time ago and I fixed it, the reason was the cable connecting the seat to the scooter was plugged/cutoff out when I did change the parking brake cable when I removed the seat.
Here are two threads: - I wrote about it , - I read it maybe similar

1- Paiggio MP3 400ie 2009 model seat sensor not working.
2- Seat sensor not working

Yesterday, while accidentally pressing the tilt lock switch and I was not sitting on the scooter (Lucky, I was holding it with both hands!!!) the tilt lock unlocked the tilt locking mechanism! I was surprised. In summary I had an issue which was due to the cable (as above) was cut off, I had a friend connect the cable and the tilt lock worked perfect, but I never tested it while not sitting on it (it worked before I change the parking brake cable), I never thought of testing it while I am not sitting on it, but now it locks and unlocks while I am not sitting on it (tested it many times).
My question, does the connection for the cable under the seat has like 3 small cables or is there anything that I need to be a ware of in relation to that connection (under the seat)? or what could be the possible problem? It locks and unlocks by the tilt switch, and unlocks when I give it power by the throttle.
thanks a lot for your comments.

whomever bypassed the seat sensor, thus the tilt lock now functions with out anyone sitting on the seat.

Only two wires in the pigtail to the seat.

Go back to the other post and look at the diagram --> Seat sensor not working

May need extra hands, but I would want to do a continuity check between the seat connectors and the control box.

Either the seat itself is stuck "on" or the cable is shorted somewhere.

A short won't do it. It has to be at about 3kohm.

Thanks for your comment, but we did not do a bypass (as our knowledge) we only connect the cables together again. we stripped the plastic out of the cable from both sides then connect each wire to the same one, and then put the electric tape (black colored) to cover them and that is it. we did not touch the fuse in the seat, (sorry to be detailed, I am not mechanic and I don't know much of the terminology so I am using basic English).
thanks,

Thank you, I will ask a friend who know about this more I do. Thanks for your comment.

Its a reference to a 3 kohm resistor. If the circuit doesn't have the right amount of resistance it won't behave properly to bypass the seat sensor and may trip a fuse.
