Locked Replacing Clutch switch - questions on connectors

 

I¡¯m replacing the clutch switch located at the lever on my 76 R90S. The existing clutch switch has a brown wire and a brown/yellow wire that go into the headlight shell and plug into the connector board using female connectors. The clutch switch on my 77S has a plug instead of the female connectors and plugs into the harness outside of the headlight shell. The only replacement switch I can find has the plug connector. My plan is to cut off the plug, feed it through the headlight shell, crimp on the female connectors and plug it into the connector board. Few questions¡­

Is this the right approach??
Type of female connector and a good source? Do I just use what I can find at local hardware store?
Is this a stock set up? Everything I found on the web showed it set up like my 77S. The switch and wiring all look original?

Hi Peter,

That was exactly what I did on a recent 74 R90/6 upgrade. The bike didn't have the clutch switch and customer asked if I would add one. I bought the switch from EME, cut the cannon plug off, and added female connectors. I use plain connectors, soldered and crimped with custom cut shrink-tube. For most of my connections I use a product called NO-OX-ID, an electrical contact grease. Dielectric grease does not conduct electricity, however NO-OX-ID does and has anti-corrosion properties, which is excellent for our bikes.

I hope this helps,
Scott B.
 

Scott,
Thanks, it helps considerably. I was questioning my plan on the repair. I¡¯m not having any luck sourcing the female spade connectors. I¡¯m hoping to find ones that are the same with the side connection. The local hardware stores only have the female connectors that the wire feeds straight in rather than sideways. Where might I find them?

Also, was this the original set-up on 76 models? Where the clutch switch goes into the headlight shell where in later models in connects outside the shell?

Thanks!
Peter
 

Hi Peter,
MAX BMW:



Section 61-Electrical System, Parts 6 and 8.

61 13 1 352 577 - Cable Socket Female, 90 degree
61 13 8 061 761 - Cap for Flat Plug, 90 degree

I'm not 100% sure on the original setup, but I do believe this was how it worked for the R90S models. Others, who know the model and year differences better than I will jump in and correct me if I'm wrong.

Scott

I have some side connect female ends I can send you today. The gauge size should work
although it looks small. I tried it on the end of a /5 and 1974 blinker switch wire and it was perfect. These terminals are difficult to squeeze because the crimp part is ¡°on top¡± of the?
connector, not hanging off the side. Send me your address and I¡¯ll stick some in an envelope. [email protected]
