I'm not grounded, but it should be (turn signa vs rpm gauge)

I think i have a ground issue: When the turn signal is on, my rpm gauge is effected, shown by the gauge who moves up and down.
I'm trying to find the ground cables and connections: Could someone point me out where they are on the bike before i dismantle it completely?
I want to look at them all, due to strange issues (brake light don't allways does it etc)/

Much appreciated in forward,

Richard

Hi Richard,

Check the state of the battery charge before you do anything.

Cheers
Paul

I'll do, merci.
I thought there would some other issues then.

Hi,
Measured the battery, only 9,5 V.
Started the engine, only ca 10 V on the battery.
Charged it till ca 12,9 V, battery seems good (YPVS control works fine now)
Should i change the stator or are there other things to check?

Regards,

Richard

Start with the regulator-rectifier. Sometimes it is just the reg-rec having a poor ground. It is grounded through the case/body so a cleaning and light sanding as well as a clean frame is necessary. If it isn't a poor ground you can test the reg-rec with a meter if your meter has a diode setting. It is often easier to swap the reg-rec. There are plenty of them around. Same unit used on TZR250 and RZ350, as well as others.

Check the reg-rec connector as well. Contact cleaner on both plugs.

If that doesn't fix it for you your next step is to meter the stator.

Just ordered new rectifier/ regulator, just in case. If it's in i'll look into it.
Thanks!

Okay, rectifier/ regulator is okay, grounding is good (measured on several points)
Stator: Allso good.
Changed the coil: Bad connection on wire/ spark plug (had one in stock).

If it isn't solved i'll try extra grounding, i'm down in ideas... Ground from battery is a little bit tiny. First ride the bad thing. :smt003

To fix a problem on mine I ran a separate ground wire from the rectifier to the frame and it was cured. I would have to look at my notes to find out what the exact symptom was. My rectifier is relocated on a powder coated tray under the fuel tank so it needed the discrete ground connection.

As John said aboveā€¦this is potentially an easy fix if it is a rectifier ground problem. Sounds like maybe it isn't though.

Good luck.

An update: Thought it wa solved, but problem started after a while again.
After the winter i noticed that the battery was down, bought me a lithium one.
Now i can say (after 2 month) that this solved the prob.
