My '86 FJ1200s shows battery voltage at all rpm's, what the heck? Fuses are good, all the wireing is good, what's up? It's an old bike but it's only got 14,986 ml.s. Looking for help here, anyone out there?

I think he's saying that he sees a constant 12 volts.

Dead alternator or regulator (except that usually results in overcharging).

Make sure the connector with the red and brown wire under the left side cover is making good connection.
