I was getting some pretty strange and much higher than normal readings on my BMW. Not a GS.....but they sure did not make sense. Went and got the other "and exact same" multimeter and.....back to normal. A new battery fixed the deceptive meter.

It is not normally possible for a 12 V battery to read over 15V when not being charged.
Do this, turn on the bike, do not start, wait one minute. . If your voltage in this condition is over 14 V then you have a meter issue. Rod |

OCV (open circuit voltage) for a fully charged automotive battery is ~12.7 volts. With the engine running you should see about 14VDC, maybe a bit more depending on RPM. Check your VOM...something isn't right. |
