Title: Battery Drain
Post by: kennyjd on September 07, 2019, 03:45:13 PM
My 955i is fitted with Triumph 2 stage heated grips ,They seem to be the cause of the battery drain that is going on at the moment,  There is no current  to the toggle switch with the ign off, which is correct, but unless I pull the fuse for the grips the battery will drain if the bike sits idle for a few days, I first thought battery and fitted a new one but that was not the problem! battery is fine as long as the grips have the fuse removed, The grips work fine in both settings otherwise!! If I remove the power cable for the grips from the Aux socket I can still get 13.5 volts on the purple wire feeding the aux socket with the ign off, I thought with the ign off there would not be any current at all! Any suggestions please

OK, Aux socket and Heated Grips do use the same fuse, and yes, purple wire is "always live". Heated grips have a relay behind headlights. Im confused by your "power cable for the grips from aux socket". The proper feed cable for the grips is again buried behind the headlights/instruments.

By power cable for the grips I mean the cable that plugs into the aux socket incorporating the relay and associated wiring for the grips and rocker switch, As a matter of interest the relay gets warm even with the ign off! Possible Culprit??

That would be my guess, yeah possible

Relay fault sounds likely.
Can you pull the relay easily?

I have the fairing off so that I could access all the connections! so yes it is easily got at, I will pick up another relay from the local autoelectrical shop and replace it and see where we go from here!

Pull the relay anyway, if its just for the grips.
You should at least be able to see if the drain has stopped, and you'll know your working in the correct area.

Removing the fuse has the same effect !!

That depends on whether the fuse is only for the grips, and is the fuse for both the control side, or the switch, or the main drain side of the relay, or the actual power to the grips. Hopefully not doing the old suck eggs, but the whole idea of the relay is to allow a low power switching of a high power circuit, and depending on the location of the drain, you need to understand the relay incorporates two circuits, and the drain may be on either, both, or between, so removing the fuse from the switch side won't help if the drain is on the high power side, if the relay is bleeding power between circuits, or providing a path for power due to corrosion/water inside.
