Locked Re: Switched power connection

 

开云体育

Hi Jerry,

I connected my auxiliary power panel to the rear brake light switch located by the rear brake pedal. It’s been working great for 15 years.

Does anyone have a suggestion for the best place for switched power connection at the towards rear of a ‘74 R90S? I am adding some Hyperlights and need switched power as well as brake, tail and ground which I can easily connect at the tail light. I can run a wire all the way from the starter relay (green/black) to the rear, but maybe someone knows of an easier connection.

Locked Notes for restoring your 90S

 

Hi
I read through the posted messages and there was one detailing some notes one member had made while restoring their 90s (s) and had made the notes available to a fellow member. I was wondering if the person who had the notes would be able to forward me a copy to help me with my 90S restoration project which I'll start soon.

Thanks,

Richard.

You can hold the 13mm socket with a vice grip and the then the 4mm hex wrench can fit inside the socket to hold the damper rod.

Now I need to find a 13mm wrench of the style to drain fork oil while allowing 4mm hex to hold damper rod. Some kind of offset box wrench. I'll bet someone here knows what its called.

@Donald Walter. Do you have a link to that website for the repair manual??

I welded a 13 mm socket to a short rod for a handle and then the Allen wrench goes up the middle to hold the fork damper. A local welder can do this in 30 seconds.

To all those removing clusters. The three 10mm bolts do not need to come all the way out,
As there are slots in the metal bracket. Just loosen them a few turns. Gently lift the cluster and with a very small Phillips remove the small screw in the rubber plug and stick to a magnet or a piece of tape and set aside. Now carefully rock the plug back and forth as you pull out. It is ok to put a small flat screw driver under an edge to get it started. You can also use WD-40 as a lubricant. Why all this care? Well the small pins that are in the cluster are very delicate and are often corroded onto the plugs. It is possible to rip a pin out. If it does not come at first, try some more lubricant and let it soak in.
I’m not saying this happens in every case, many come right out.
Re assemble with electrical conducting grease on the pins and sides or rubber plug.
Also grease the threads of the tach and speedo cable connections for future ease. No need to crank these down really tight also.

I see the heads of 3 bolts below the cluster. I assume I disconnect the speedo and tach cables, remove the 3 bolts and go from there. There must be an electrical/warning light disconnect somewhere in the mix. Hopefully its a quick disconnect type.
Thanks for the education and resource info!

I got the Repair Manual pdf from the Vintage BMW website earlier and subsequently joined the organization. Much more relevant to me now than the MOA.
Cluster, tach cable & grommet removed. Will send cluster in for service. Thanks.

Shop manuals are available online. Worth pursuing. The three bolts just need to be loosened and pull up the cluster. The electrical connection is a larger than you'd expect plug secured by a tiny little screw that is easily lost. It's also not real easy to get this plug in or out.
