I have a problem with STOP function on my BG3404 and I'm certain that the problem lies with the contact springs of the 15RL1 motor switch nonetheless, page 18 in the SM describes '15 p in the direction...' and this baffles me i.e. what does '15 p' mean ?
I have attached a JPG page 18 file with the diagram and description and I hope someone can enlighten me....
Thanx, ICE
The 15 P is the pressing force in ponds (Kiloponds is an old term, today Newtons are used) 15 P is 0.147 Newton

...or approximately equal to the gravitational force experienced by a 15 g weight at sea level, i.e quite little.

How much will that be at 2.500 meter over see level (where I live)😂

Gives you a good excuse to take a trip to the seaside to wet your feet in the Pacific and adjust it there 😁
(around 0.08% less, if I calculated correctly...)

That will be me and my BG alone to Acapulco, a very good reason to go there.

I thank you fellow members for your gentleman and scholarly replies. Amidst my confusion at the SM description, the 15 p (pressure) is the key to the 'STOP" malfunction..........Page 18 JPEG
In brief after the 1st reply to my query, further examination and tinkering has revealed that the 15RL1 relay is activated via PAUSE +/or STOP. PAUSE is engaged by one side of the rocker switch and this has no problems as the clearance between C and D contact springs falls within 1 mm.
The STOP function doesn't always engage because as the rocker swings to the other side of the 15RL1 relay, the plastic lever that disengages the tonearm doesn't travel far enough (just a tad short). I witnessed this as I had the bottom cover open with the BG3404 suspended. With a very minute nudge on the plastic lever, the STOP process completed it's cycle.
Conclusion: the C contact spring must be bent forward (more pressure) in order for the plastic lever to swing outward just a tad more and 15 p is what is required !
I'm not sure that I'll arrive at the correct P or Newton force however "direction is not important, results count'!
Thanx for your enlightenment and humour...Regards, ICE 😁
Sorry for the thread steel, but sometimes it has to be fun and not dry as my first answer, Mika helps a lot in keeping the spirit.
Hope you get your BG up and running good🙂

I think so too - they probably had some kind of a spring gauge at the factory to adjust this, but you can certainly do with trial & error once you understand how the mechanism works, and you seem to have figured it out. Good luck and stay with us - we often provide some relevant advice as well! 😂
