Neutral switch

Postby Toon » Thu Aug 23, 2018 9:52 am

Hi there, hopefully someone can help me with the following problem:
During a vacation trip in Poland suddenly the Neutral light didn't work, no issues however with changing gears.
after a good night sleep the neutral showed some life and burned normal but after a short while it stopped once again (I could notice that by the lack of flickering from 1 to 2 and during the stops at stoplights).
Next morning no signal but after openening the throttle the light came on for just a moment.
I have to start with contracted clutch otherwise the starting procedure is the similar to that with an active jiffy.

any clues for somebody?
greetings Toon

Sounds like a dodgy neutral switch. The neutral switch https://www.motorcyclespareparts.eu/en/ ... ectrical-1 item 6 on diagram it is down near the gear change spindle. It is just a switch that makes a contact on the neutral (-ve) feed to the lamp when you put the gearbox in to neutral. Because it on the -ve side not the +ve side you have to be careful which way round you put the bulb if you change them to LEDs. See my blog viewtopic.php?f=55&t=3327 page 24. Hope that helps.

Opened the side cover this afternoon, cleansed the sprocket and checked if the switch was still functional with a volt- meter. In the N-pos a current was seen and in 1 the current wasn't there: ergo nothing wrong with the switch. What else? Any ideas would be welcome.

Next week the coolant system will be removed and I'll be able to remove the switch for further inspection I expect that some faulty wiring inside the switch is causing reduced currency. Direct connection shows no problems with light or wiring. It's always a puzzle......
