CB550 Neutral Switch

(1/3) > >>

Neilw:
I've got the points/timing roughly done, so I can try and start the bike.

However, the start button does not work - the whole RH switch is new. I know the bike turns over by shorting the solenoid, so as part of the diagnostics I've got to the Neutral Switch, which doesn't seem to be working. When I dismantled the bike, I didn't note how the neutral switch went together, and now, in whatever configuration I try i can't get it to work.

Could someone post a pic of how it goes together? I know where the green/red wire goes.

Also, the Stator doesn't quite look the same as the one in the parts book; the tab bit is a bit smaller, like something has broken off, but I can't see what difference that would make.

Thanks for helping.

HA Ha just seen the doodle impression on the paper, it's not what it looks like, but apologies if anyone is offended lol.

Look as if the contact on the spring part of the neutral switch is broken off.

Look at a picture of the switch on CSML or Google it.

Test the solenoid, they can fail.

So does the broken-off bit need to make contact with the brass part of the neutral switch? Am I correct in thinking that if it touches the brass tab, it completes the circuit to neutral, and when it's just touching the plastic bit around the edge, the light goes out because it's in gear?  So i'd have to mount the switch part with the brass plate facing outward?

If you search Neutral Switch on this sites search facility there are pictures of it.

I found a very useful video on YouTube that explained it perfectly.

I can see that the Switch has lost its locating tab and the stator has a broken contact. so no wonder it didn't work - however it was working before I dismantled the bike, somehow!

I've already had a quick search around, and these parts seem rarer than hen's teeth. Is there a way to repair the Stator, so I can create a contact point? I'm assuming I can glue some plastic onto the switch to create a locating tab.  Of course, the best option would be to replace both.

Anyone have any spares lurking :-)
