Hi

So I'm finishing the last few pieces of my project, and I'm having trouble with the rev counter doesn't work on my new Koso DB01-RN speedo. 
I have connected the two wires which are supposed to be for the revcounter brown/red on koso, and black/blue from the BMW. 

I haven't measured if there is any poweroutput on the black/blue wire from the BMW (Pin16), and unfortunately I'm not able to do today, since it is not on my address.. From what I have read around the forum, people don't really seem to have any problems with the revcounter on a new speedo. But I'm wondering if it is a known problem to have a loose connection around that wire?

The original cluster worked all fine when I split the bike apart and it is on a 1987 k100 RT 

HI!

Have you checked the plug from the ignition module, ( the smallest one, not the big metallic one) i remember to have a similar issue when installed the minimotogadget speedo, and it was a rusted pin , the black\blue wire from the coil was so dirty that didnt work properly , and the signal from rpm didnt worked.

clean all the connectors and grounds well !!

cheers

And your bike is lovely!!

great job Tommy

 Of course that could be the problem! I will check the connector when I pull the tank of soon and when it is of, i will cut off those fairing mounts they annoy my mind too.
