I’m considering a totally stock unmolested 2017 S40 with about 5000 miles on it that needs some help (I got outbid on the 2022 Royal Enfield Himalayan I was entertaining as my next project).

The seller says he forgot to unplug the battery charger last summer and now the bike won’t start and has a “short”.  I’m not sure I buy the story, but assuming it’s true, what would likely be “fried” from overcharging the battery?  The first thing the juice would hit is the starter relay, right?  Yes/No?  Decompression solenoid??

I know it will need a complete fuel system cleaning (tank, line, carb) after sitting up this long.  Hasn’t started since early last summer per the seller.

Thanks Dave.  I didn’t think an overcharged battery by itself would be the issue.  Just going off what the guy told me.  The bike is in Austin so I haven’t seen it in person.  I’ll see if he’ll entertain some more questions.  He said it does “click”, so I’m suspecting the starter is toast from too many rapid/long attempts to start.  It seems like the classic fail of frying the starter trying to fire up a bike with a gummed up carb.

Thanks Yoshi.  Agree.  Probably has a dead cell or two.

Thanks 04Savage.  I ended up not buying this bike as a project.
