Title: Voltage Gauge jumping
Post by: Magnumeng on June 05, 2016, 01:45:22 PM

Hello all,

I was out riding the other day and after the bike warmed up the voltage gauge dropped down to just above 13 when it goes back to idle.  As soon as I give any throttle it goes back to 14.  Just had my voltage reg, stator and battery replaced a month ago.. Did i burn another set up again?

Bike - 13 SE Ultra
Mileage - 14500 (I know i dont ride enough)
Air temp - 90+

Any recommendations is greatly accepted.... Hate the stealership

Does it remain steady or bounce when going down the highway? Not back roads but a steady 60+mph hi-way run? Any movement or bouncing or steady?

It remains steady....

13 is still ok at idle. Steady means your find on stator and voltage regulator (usually). Battery runs bike at idle, but still good at 13

The voltage gauge is not the best. 

If you have any questions about it test it at the battery, start with a fully charged battery (about 12.7 at rest), start the bike (it should go down some as it replaces the juice used to start) then after about a minute hold at about 2,000 RPM and it should be close to 14 volts, 14.2 is better. 

If the battery is not at full charge the voltage will read less as it is trying to charge the battery too.
