I have purchased some Oxford heated grips for my R80G/S and have some concerns about wattage. The alternator only puts out 280 watts on the stock unit. Upgrades are out there but pricey. If it was cold enough to turn on heated grips chances are I'd probably want to use my BMW heated vest too. The grips can draw up to 4A max and I am really not sure what the vest pulls but I would guess about 2A or so. No idea what the overall power consumption of the stock bike is.
Has anyone had this combo on their G/S?
Did the battery survive or does the voltage slowly drop?
I do have a Euro model and the ability to shut the headlight off but in Canada daytime running lights are the law so that is best avoided.
