I was asked to repair a DUPLO locomotive (52088) The one that has a rotary sensor at the front axle.
The problem is that when I push the top button the horn sounds and it moves forward for 1 second. Then stops. Every time....
When I push fast two times the stopping sound also works and the wheels stop directly.
I've dismantled it and looked if the reed sensor was defect. But that works good.
I looked at the motor unit but do not see any strange things.
The water intake "sound" works fine.
When I bypass the print plate and put the + at motor directly the motor runs fine too.
I cannot find what makes the motor stop every time
What could I check or do more?
Sincerely
Rob
