Gerbing Heated Clothing Difficulty

[Nudibranch]

Hopefully somebody on here will be able to speak some sense about this.

2010 GSA with sat nav, autocom and Les Wassall HID headlights (not spots).

Getting cold now so plugged in x2 Gerbing jackets (77watt each) and x1 pair Gerbing gloves (27watt) for me and the mrs - all direct fused connections to the battery. Take a spin up the M6, feeling toasty, but after and hour or so the brake warning light comes on intermittently. Clothing still hot though.

Return home safely if not a little concerned about the warning signal, and the bike goes back to dealer to be checked out; battery apparently being overcharged. Fault rectified by BMW. Told a common problem when using heated clothing.

Have I been told porkies, or is 180watt for heated clothing just too much to sustain on a GSA? (A 720watt alternator should be able to cope with that whilst running everything else should'nt it?)

All comments (wise or not) welcomed.

Cheers, Nudibranch

I think you are being told porkies - can't see a problem with what you have connected. What was it that they fixed then?

Sorry don't know how to respond to multiple quotes as yet.

Beemerman59 - I thought so too. Not sure what was fixed. I was led to understand that the brake warning signal was a manifestation of overcharging the battery. The error causing the brake warning signal was corrected, there was no actual brake problem as far as I am aware.

jasext - Thanks for that will give him a bell. When cold the Mrs is not a happy pillion!

may be worth sticking a meter on the battery with engine running and see the voltage diff from clothing on against clothing off, it maybe that the load is changing the charging voltage one way or the other, and this is upsetting the ABS (although I was always led to believe that too low a voltage brought the lamp on not overcharging but I bow to the supeior knowledge of the BMW mech)
