Confuse and without resources
« on: August 12, 2018, 07:06:36 PM »
Hello all,

I drove down my brick, a 1990 K100rs 4v, from Montreal to Cancun, it was amazing, but now, I have problem with the best. It all started on the road.

1-first my fan stop, the fan was clearly dead, thank to a brother, I found a replacement on the road, replace it, but was not just the fan, a sensor or I don't know what... (so I installed a temp switch, to survive the trip)
2-after some very hot day in Texas, the lights started to act out, they were not turning off, even with the ignition off, some people on the internet suggested it was probably a dirty ignition, so i clean the SH'' out of it, but no result, so I started to unplug the ground at night, I still had 3000 km to do
3-the bike started to not starting, but in random bases, sometime was ok, other time I had to ''start it on compression'', more the days were passing, harder it was
4-finally arrive home, in Cancun, toke my contact cleaner, clean every plug, contacts, name it, motronic cable, every plug... Result, now the light are off, but they don't turn on anymore, the blinkers also stopped working, and the bike doesn't start anymore, even and second...
5-trying to identified the problem, I found out, 2 dead relay, and i kill one by mistake, so I'm -3 relay, find a temp relay from a car shop, don't think it's a ideal solution, but parts take 2/3 weeks to arrive here and the Motorrad in Cancun, never work on a K100, not sure, think it was not sold in Mexico

The Motronic qive me the error 1133, not sure what to do from there, the electrical situation of the bike is a nightmare, the previous owner butcher cables, remove the abs for I don't know what reason... 
At that point, I'm just lost, I don't know what would be the logical step to follow, I feel like these more then 1 problem, and I'm basically alone to resolve all that.

Other info about the bike, last owner as changed the front blinkers, for LED, and the headlight for 2 smaller headlight, bypass the side stand switch,remove the gas and temp gauge, but I putted back the gas one, and as far as I know, that's it.

I also have a unknown cable, cut, getting out of the hall... the smaller gauge one

The wire in the photo was probably for the temperature gauge. 

As far as other problems, have you pulled the starter and checked and cleaned the brushes.  Worn brushes and a dirty commutator in the starter will cause a lot of electrical problems.  Having a good starter motor is important for success in electrical troubleshooting.

You also want to make sure that the ground connections on the side of the transmission and under the tank are all clean and tight before starting any serious troubleshooting.

Thanks for the tips, I will clean that this week.

So you think it's the temp gauge, very possible, anyone as a photo of the path of that cable, I would like to fix that too.

Thank you
