80 GS1100E Battery light on dash stays on

[woodman]

How do you shut off the battery light on the dash, I guess its to show low water elev in the battery ? The battery is charging. Dont have an owners manual to tell me what it is for.

I'm assuming that you are talking about the light in the check panel? it was on on my bike and if i remember right i had a loose ground and fixed that and the light hasn't been on since.

That light has NOTHING to do with battery charging.

You are correct about the electrolyte level. The stock battery had a port on the top to accept a sensor that monitored the electrolyte level in one cell. You can still get that type of battery, but you would be better off just buying a sealed battery and connecting the sensor wire to a switched power lead, like the tail light.

Thanks, thats what I thought because my 82 GPZ750 has the same setup. So all I need is switched 12 volt power to shut it off if I understand you then ? I already have a new conventional battery in it.

Once you've tried the battery route and thats not worked then it can also be the control unit thats at fault. This is found under the tank by the coils. There's no fix other than changing the whole unit.

Yes, that's right. Find the sensor wire (I think it's green), see if it still has the sensor on the end of it. Remove the sensor, if it's there, find a way to connect the wire to the tail light wire, coil supply wire, horn wire, anything that is only live when the key is on.

Will do, green wire is still there, thanks a lot

Is it a solid green wire, or one with a stripe?

Any idea as to where I should look?
