Charging check

[Guest]

On a car it's relatively simple, with a decent voltmeter, to tell if the system is charging. You'll notice a voltage change of a volt and a half or so when the engine is running. Apparently this doesn't apply to M/C electrics as I'll watch the meter bounce all over the place from 0 to 20+ and all points in between. Why is this?

Hi,

The reading should be more stable than that. Make sure your meter has good connections, PUSH the leads into the battery terminals. Where is your r/r grounded? If you can't get stable readings with a good multimeter then check the AC output of the stator. Perhaps it's time for you to go through The Stator Papers? Keep us informed.


Thank you for your indulgence,

Not normal for any D.C. charging system!

either your vom has taken a dive, or your R/R is letting A.C. leak through. you can double check the vom on a running car.

if the R/R does leak A.C. the vom would be trying to sample the voltage level of a moving target by trying to measure the voltage at various points of the sine wave.

Change the battery in your voltage meter and or try another meter. As the others mention, this should not be the case. Voltage on a running bike should go up with revs and on a properly charging system should show high 14 low 15 volts at a max of 5000 rpm. As the revs drop so should charging voltage. In all cases it should be within 12.5v to 15v. Bouncing around is not normal.

Try again and let us know.
