I've posted a couple of times before about battery issues, most recently in this thread
, but I thought it'd be worth it to start a new one.
A quick summary: once I had trouble starting the bike after it stalled in traffic on a hot day. Engine just wouldn't turn over. I waited a few seconds and tried again and it started up, but it was annoying. In replies a few people suggested the OEM battery was too weak and I should get a new one.
And on my last trip I got fed up with the accessory circuit cutting out every time I started my bike. My alternator is great, the battery voltage seemed good (12.4-ish), and the dealer did a load test and found it fine. Yet unless I've just pulled it off the charger, every time I start the bike I get a red <!> and a battery icon in the display, and the GPS and Autocom lose power and reboot.
After pressing the dealer, they agreed to replace the battery under warranty. So, over the weekend I got a new OEM battery for my '07 K1200GT. The accessory fault problem reproduced at the dealer the 2nd time we started the bike. I took it home and put it on the charger, and it was fine for the first start the next day, but after that every time I started it I lost accessory power and got the battery warning again.
Do you have the same experience with your GT when starting it?
For those of you with accessories, is it just the canbus accessory circuit that cuts out? Could I solve the problem by powering everything from the battery and switch them all off the front parking light?
What's the brand and, if available, part number for the aftermarket battery for the K1200GT? Anyone know if the (too damn expensive) canbus-compatible BWM battery charger will work with the aftermarket battery?
