Default Battery loses charge when it rains

I bought an '89 1000F a few months back. Has anyone else had this issue: my battery seems to lose charge when I ride in the rain. When it's not raining, the battery seems to hold its charge and the bike will happily start each morning. However, if I have ridden in the rain one day, the next day the battery is flat and the bike won't start. I can normally bump start it, but the other day I couldn't even do that.

Water getting in somewhere it shouldn't? Suggestions on where to look and what to do appreciated.

Thanks for the replies, guys.

The lights seem to be working fine (maybe a bit dim considering there are twin globes). All other electrics work OK. How tragic is the horn on these bikes??

The only non-standard wiring is a trickle-charger wire connected to the battery so I can charge without pulling the saddle off etc. It looks OK, but I can remove it and see if it makes a difference.

I guess I'll just have to start pulling things off and look for water ingress.

Have one of them myself wire tied to the rear peg.

Make sure the charge plug ain't gittin' soaked.....that'll knock that little acid box
on it's ***.

I was thinking of replacing it with a pair of Fiaams: a bit more impressive. But I'll kick off with disconnecting it and see if that helps with the battery issue.

Thanks again.

Putting this thread to bed (3 years later sigh...), and if anyone happens to read it: in the end the issue turned out to be nothing more mysterious than a dying stator - the battery was losing charge come rain or shine. I replaced the stator and all was good.
