@ Tino, diese akademischen Spielchen habe ich zu genüge gehabt, bin sozusagen satt.
Ich suchte nach einer einfachen Möglichkeit zur Berechnung.

Oh, and what is a 'red light' - some LED device?

yes, a LED red light, worked only when i connected it reverse
plus multimeter was Reading -6 volts

can the bike engine run ? lights, and horn worked well

PS: what does 'once a man indulges himself in m.' refer to ;^) ?

swapping bat connectors worries me, but i will do so, probably next weekend

i am getting the necessary tools to carry on the work, such as a piston stopper, trying also to get a larger DTI arm to reach piston top through the spark plug hole,....

i will also print an angle disk and place it in a CD disk

lots of thing to prepare before

this weekend was fruitful to read all the documents, and learn about the theory, also set point´s gap correctly to 0,3 /0,5 mm (yeah 0,3 without manual advance is 0,5 with manual advance at máximum

i prepared a very freaky installation of an ammeter to check battery charging (will show you now)

p.s. "what does 'once a man indulges himself in m.' refer to ;^) ?"
well captured, Dappsull, is english writer Th.de quincey most famous sentence:

"If once a man indulges himself in murder, very soon he comes to think little of robbing; and from robbing he comes next to drinking and Sabbath-breaking, and from that to incivility and procrastination. Once begun upon this downward path, you never know where you are to stop. Many a man has dated his ruin from some murder or other that perhaps he thought little of at the time. Murder Considered as One of the Fine Arts (1827)."

i love the apparently absurd progression of things in his thinking

ok so the AMMETER installation

i was visiting the Essen motor show and found a Little nice object, a "Charging/discharging" gauge made in france in the 30-ies

it is essentially an ammeter (to measure Amps), so well what can i do in the R2 ? that was the question, was it posible to check when the batt is being charged or not ?

i went searching for a Bosch similar device and found nothing

i ended up in the UK, found this lovely patina ammeter from the 40-ies

then the question was how to prepare and where to install, so to make a long story short here you are the pics, any comments adn questions are welcome

it worked well :-) seems that the lichtmaschine ist kaputt :-(

regards

Seems you're getting serious ;^).
Anyway, in terms of battery hook-up: can you check, if the '-' connector goes to chassis (which I assume should be the case)? But only then any measurement makes sense of course. Horn and lights are independed from polarity, but neither are the generator nor the regulator, even the ignition to a certain extend.
You are well equipped, so you can also follow up on resistances once you have acces to the generator and the regulator.

NB: interesting to get to know that ignition timing advance is changed by different point distance settings. An obvious way, but I never came across such a procedure (but I have of course only the super modern 1966 BMW).

Good luck!

My 2 cents.

You can calculate the current by measuring the voltage drop across a known resistance, no voltage drop the likely no current flow. The current can the be calculated using Ohms law.
Most current meters measure voltage drop and display current as result of Ohms law.

Tino

dear tino. this is extremely interesting, never seen this before, thank you so much for this lesson

but, my regulator is integrated inside the dynamo, so it will be difficult to follow this procedure:

"To polarize a Bosch or other series field dynamo for negative earth

 Disconnect the wires from the dynamo. Run a wire from the earthed (negative) terminal of the battery and hold it onto the DF terminal on the dynamo. Run another wire from the positive terminal of the battery and "flash" it onto the D+/61 terminal on the dynamo until a small blue spark can be seen.

The dynamos field is now polarized for negative earth and ready to safely connect to an electronic regulator."

if you can advise on how to proceed i would be very grateful

Usually it should be a Bosch F-Regler.

http://nsu-superlux.vogo.org/assets/images/Reglerk.jpg

In this case you have to hot-wire the cut-out (Rückstromschalter). Just for a split second.
For that remove the cover on the back of the generator.

thank you, Tino, that is usefull information,

i beg your patience, hot-wire the cut-out ?

ok, i need help to identify the cut-out, and also to know what is to hot-wire, and how to do it, it seems that i have no idea of what you are talking about, sorry

i will open the regulator and see what is inside first, i will take some pictures and come back here

Hi, better put the degree wheel on the crankshaft.
When the crankshaft makes one turn the camshaft makes only a half  ;)
Also the chain has to much backlash for a proper result.
This could cause several degrees deviation to the crankshaft.

oh, Tino, you are right ! ....scheisse ! (sorry)  :(
oh i can do nothing with this, there is no way to fix it to the crankshaft !!!

i will use only the piston stop, then

Re: R2 setting ignition
« Antwort #51 am: 04 Juni 2017, 10:19:16 »

so i did it yesterday, and it was a success

PREPARATION:
first i changed the battery poles, that were mistaken, and then checked the polarity in the coil, now terminal 15 is positive and 1 is negative, alles in ordnung !

then i rechecked the points gap: is 0,3mm without advance and 0,5mm when maximum advance

then checked for TDC using a plastic rod throught the spark plug hole, it was a bit empirical thoug, but i was able to make a painted mark in the flywheel, so i knew where i was

then using my other engine that is disassembled i set the piston stopper at 9,5mm: i removed the cyl head and place the piston at 9,5mm BTDC, then i adjusted the piston stopper accordingly

PROCESS:

i went to the motorcycle and placed the piston stopper in place in the running engine

i slowly moved the piston until it stopped, i made a mark in the flywheel for a 9,5mm BTDC

using my 6 volts red light (a diode, so it has polarity) i connected it: black cable to ground and positive to the condenser terminal in the ignition module (at last that now polarity is correct:_)

placed the lever in the handlebar at maximum advance, so ignition module is set at max advance (remember that this is moving the points anti-clock wise)

then using the cable adjuster of the ignition module i tuned the position of maximum advance so the red light (and thus the spark) was just switched on in that position of the crankshaft (9,5mm BTDC)

CHECKS:
once done i removed the piston stop and rechecked:

1- with maximum advance i checked that the red light just switches ON (spark firing) when passing through the 9,5mm mark in the flywheel

2- now i put no advance with the lever in the handlebar

3- i checked when the spark is produced in this condition, and i found that spark ignites AFTER TDC !!! only a few degrees but ATDC, surprising !

ENJOYEMENT
and finally i started the engine, wow, so loovely !

no knocking at all, started very well, i assume also new points and new condenser where part of it !

AKNOWLEDGEMENTS
thank you all very very much, now i understand my motorcycle (it has been 10 years ;-))


...it will continue ...
