Just curious, does your battery last burning maps from laptop to ecm? I need to plug my bike in a tenderer to fetch & burn, otherwise if I play around just a little bit I get an unable to connect error. How's yours?

Yeah it does given you have a good battery. Never had that problem though.

You did take out the headlight fuse?

If the dual headlight on mod is done on the Lightnings you have to unplug the connector instead of fuse...at least on mine.

As long as you don't overcharge the battery just precharge it before doing your work. OR I just unplug the headlites and that usually does the trick.I have had to use an 2 Amp charger many a time, to finish my work on someones bike.Just means they should Buy one of the Battery Tenders here in the shop and pig tail installed [usually] keeps it up to par.
