- You find (especially with a digital instrument) with 12V systemens
only about 10 and with 6V systems around 3 Volts when you switch on
lights (sometimes already without lights).
=>> this is NO indication of failure !
- Funny thing is, that when you increase engine speed, voltage may
drop even lower, though your headlight shines brightly.
No worry, as long as the headlight shines brightly (in case of doubt
when driving with a battery that this comes from the battery only,
disconnect the battery for a test) all is ok, even with the meter
showing abnormally low values.
The system delivers direct current with some underlying frequency.
This may fool the meter.
He who dos not believe this may check again with a high
capacity condenser in place of the battery, dthis condenser
smoothens and you get more normal readings, even without battery.
