Hi All

The 1991 K100RS is slowly progressing from when it first arrived on the trailer from up north...

...but the real issue for this topic is related to in here

https://servimg.com/view/19367170/14

...when I turn on the ignition key the blue relay in the picture (maybe a load shed relay?) is clicking

...when I press the right blinker button both right hand blinker work fine but the blinker cancel button doesn't work

...when I press the left blinker button, the right blinkers work fine but the left blinker also come on and stay on, and the blinker cancel button still doesn't work

I have carefully taken apart the left handlebar switch, high/low beam, horn and left blinker button but there was no change....I will do the same with the right handlebar switch tomorrow

I guess my real question is about the blue relay and if the clicking there is normal or indicates it is Kaput..

The blue relay is an ABS relay and will click till the bike starts moving and it does all it's self tests.

For the blinker caper check all the fuses with a meter or better still replace with new fuses. Also this can be caused by a bad set of brushes in the starter, usually just worn out.
The bad brushes prevents the loadshed relay operating because it gets its earth through the starter.

Hello!
Before you take everything apart, have you tried to use electrical contact cleaner spray on the handlebars switches and the contacts under the tank? Spray and move the contacts in and out.
There is a link here in the forum which shows the connection that are used for your issue.

I hope you find a solution

Those splines look really good. Was the bike laid up a long time? There are plenty of threads about working over the electrics to bring them back to life with Deoxit . Basically blokes have been opening every connector on the bike methodically, cleaning and conditioning with the deoxit to ensure good contacts. Would be worth doing.

DeoxIT.

Here... Available at Jaycar. Use the red stuff.

God's gift to K100 owners.



Some people wish for world peace.

Some wish for more money.

Some even wish for a better life.

All that I wish for is that people on this forum spell DeoxIT correctly...

Thanks for all the advice it's all most helpful...

This morning I did the RH switch and apart from a minor drama drilling out the retaining screw it's now all nice and clean and reassembled. Easier to do in the morning sunshine than in the evening gloom when I did the LH switch yesterday. Now off to get some DeoxIT from Jaycar and do the ritual corrosion routine throughout the electrical system....

In reply to what sort of life the RS had before me I must admit I don't really know. I bought it from Bundaberg sight unseen on ebay as the price seemed fair and I wanted a challenge....  . The bike seems quite straight and apart from the usual suspects....leaking rear master cylinder, leaking front right fork seal and a minor but poorly repaired knock to the upper fairing (passes the 4m test though), and now some assorted electrical gremlins it's been fine. It ran ok before I took it apart, started easily etc so hopefully all my "improvements" wont change that.

The pictures I posted of the splines were before I cleaned and re-greased them with some moly paste and they looked even better after the clean, and when I can remember how to post pictures I'll put some more up here. Btw it was such a mission last night posting the original pictures I'll have to go back and reread the ten pages of notes I needed to do it the first time....

I've removed the fairing and given it a naked (not cafe) look as I want to have the option in the future of returning it to glorious RS specs if I feel the need. It has a cheapy chinese ebay headlight (but looks nicely in proportion), some fork gaiters etc to give it a classic look in my eyes, and along with doing a heap of little fiddly bits and pieces when I don't want to start any major repairs progress is being slowly made...

Anyway cheers for all the advice....

All good so far and progress is on-going
