Greetings from Latvia!
Sorry for making 100+ topic of this problem , but i`ve gone through many topics, but could not make much sense of my problem.
There is mp3 125, it came in for service (oil, filters etc.) but after these services of unknown reason tilt lock stopped working.
I`m person who came to check on it only because i know in which hand i need to grip on multimeter
So after few hours i got some idea on how it works, and what works.
Motor is ok, connecting straight on 12v it moves levers to lock and unlock system.
Microswitch is ok, potentiometer on whole assembly is rotating and looks ok.
Recently pressure sensor was replaced, but now i understand it is different system which only checks for pressure.
When i manually lock tilt (electrically or with screw at the end of motor wormgear) and start scooter, it beeps, and when i press unlock button it unlocks fine and it stops to beep, but i cannot lock it any more.
I measured "B5" wire at lock computer, when it is unlocked it shows 1v, when i start to lock it with screw, it goes up to only 2,8v (instead of 4v?) when it is locked till very end, but i could not find out how i could adjust potentiometer, so it could do 4v when it is in locked position?
Maybe i`m trying doing all this without some factory tools like diagnostic etc, maybe there is no chance to fix all this with screwdriver and multimeter?
Would be grateful for any information on what to do next in troubleshooting this issue!
