Charging Question

[unknownmanxman]

Just something thats been niggling me.. after i have started my 90 it runs at about 14Volts... but after a few minutes this drops to 13.2 Volts, and when i rev the engine it flickers between 13.5 and 13.2 volts....

Whats it playing at?

Its a 200tdi 90 by the way..

Sounds normal to me.

After drawing on the battery to start the engine it then charges it back.
After a min or two it then runs at  13.5 ish as it should.

Ahhh its normal? thats good...

So when you switch all your lights on does the voltage go back up to 14V due to all the load? or stay at 13.5ish?
