I've not had confidence in the charging system on my 02 leMans for a while (flickering battery light, left me with no power once then I changed the battery).
I've been using a battery tender to make sure it stays up, but thought I'd look into it further today.
To my surprise, the voltage across the battery terminals at ~3,000 rpm got over 17V. My first thought was a dead regulator, but then I found another thread in here that mentioned 18V charging voltage and no-one commented.
Is 17+ V normal? I expected 14-ish. Before I started the bike the battery was at 12.7V with the ignition off, so it is OK (and my meter is probably not smoking crack either).
Thanks,
Dominic
