Battery light

[Guest]

I recently placed my 83 GS1100ES for sale on the Classified Forum. While the bike is solid mechanically, I noticed the other day that the battery light remains on after I start it. The battery is new. I'm not sure what the cause is. Does anybody have any ideas? Thanks!!

There is a sensor in the battery. G/Bl wire . Pull the wire high using a switched 12V signal. Brake light switch works (O/G).

This issue comes up on a number of bike forums for bikes where there is a battery sensor that fits into the battery. From what I gather, there is a paucity of selection of batteries with the extra hole for this sensor. A lot of Yamahas also have the sensor... such as the early Ventures.

Yep. The battery with the sensor hole does exist, but not everybody carries it.

Since you apparently did not get one of those, take the wire that is supposed to go to the battery sensor and connect it to a switched power source. Posplayr suggested the brake circuit, I agree. Just in case something shorts out, you only lose your brake light, turn signals and horn. Personally, I would rather not lose the headlight or the ignition while negotiating a curve at night, the brake light is a much easier loss to handle.

With that type of concern you can put a 10K ohm resistor in series. I measured the relationship between current draw and the resistor value at one point but do not recall the values at the moment.

The 10K ohm resistor shoudl stop any potential for a short.

Is That a pun ... ?

It comes pretty close.

The resisitor will greatly REDUCE the potential (voltage), but won't stop it completely.

Actually the resistor does not limit any potential or voltage it limits current.
