Flying Duck - do you know what color wire is what? is the GREEN - fuel sender? is the BLACK - ground? etc...

Flying Duck · Posted: Wed Apr 08, 2009 9:32 pm Post subject:

Black/bue or white/blue is the power to the backlight.

Brown is ground (always, everywhere on your bike) It gounds the entire fuel gauge.

Green and yellow go to the needle mechanism.

Hi all,
I have access to a BMW K1100RS 94&Up wiring diagram. It is not clear.
Here is the picture of my new VDO 310-107d fuel gauge.
http://www.use.com/d6c703217db6355a5caa

In this diagram is total of 5 connectors.
2 connectors are on the backlight bulb.
3 connectors are on the fuel gauge.

fuel guage connectors are labeled "S", "+", and "-".
I disconnected the OEM fuel gauge at the connectors and plan to original wire harness to new fuel guage connectors. wiring harness has four wires.
Brown,
Blue,
Yellow,
Green.

I have been told that Brown is Ground.

Can someone tell me what wire would end up going to what connection point on the VDO gauge?

Thank you
kp52r11

Rich would probably know - he put VDO gauges on his bike. Hold on a bit - he'll probably find this thread.

Here is a pic of how I wired my VDO gauge. I cut off the plug from the old qauge and put it on the new one. Let me know if you have any questions.

Rich,
This is too perfect. You answered my question. I will wire it up and let everyone on thread know what the result is.

Thank you

Rich,
Can you tell me if Yellow goes to "S" terminal and Green to the "+" terminal on the VDO?

Just curious: What the temperature range on a K bike? What's the temp when it's in the middle of the OEM gauge? At the red line?

All - an update on my Fuel Gauge issue---
I am unable to the the VDO gauge to work. there must be an issue with Green and/or yellow wire.
Here is what I have done so far:
1. tested the fuel sender by removing the gas cap and moving the gauge fuel sender inside the tank up and down. I am able to see the yellow instrument panel light for low fuel go on and off as tank is coming to empty and when I fill it up. That tells me that the wires (yellow and green and blue and brown) coming out of the bottom on the tank and going towards the intrument panel and fuel gauge must be working.
2. fues are all tested and working fine.

--- I have given up on the problem for now. I replaced the fuel gauge slot with Battery Volt Gauge. Next time when K goes into the shop I will have the shop track the wire all the way from fuel sender to the gauge end to see the wire is the issue.

Thank you all for helping me troubleshoot the problem.

Hi,

I have the same problem and wanted to ask if anyone knows how the fuel level hardware in the tank works with both the gauge and the low level light.
I know the low level light works OK, but the gauge doesn't. Is it the same in-tank potentiometer that drives both the gauge and the light?? Just that I measure an open circuit reading on the wire that feeds the gauge as it comes out of the tank when I move the float. However, the low fuel warning is OK.

The gauge shows FULL when I short it at the tank connector so the gauge is OK.

At the moment, it looks like a break in the wire between the pot in the tank and the connector to the rest of the wiring harness.

None of the manuals/wiring diagrams I have show any detail of the actual fuel level sender itself.

Cheers,

Ray.

If I remember correctly from the last time I pulled the tank and sending unit, which was a while ago the sending unit to the gauge is a different connection than the connection of the unit to the low level warning light.
