Split charge

(1/2) > >>

Ollie:
I currently have a diode style split charge system. It's working well, but after buying and fitting a battery moniter, I can see that I'm not getting enought juice back into each battery. There must be a voltage drop through the diodes.
Is it possible to get an up-rated alternator? If so, where from?

Cheers
Ollie

Ollie - Give these guys a call M.K.S on 01908 225494, they supply people like Joe Edwards and Coyleys with Alternators and starters. Prices are good, They uprated my alternator and fitted it. Give them a call :)

Bob696:
I stand to be corrected on this but wouldnt an uprated alternator just give you more current rather than volts? You would still get a 0.6V drop across the diode.
It would be cheaper to ditch the diode and get a relay instead.

muddyweb:
Spot on Bob... an uprated alternator won't help unless you get one with proper battery sensing and external control.  (and that's a lot more money)

That 0.7 volts sounds like a small amount, but as a percentage of the charging voltage, it is significant.   The same thing applies to keeping the batery connections clean and secure... a volt here or there makes a massive difference.

Ahhh, yes, your right Bob.
So, ditch the diode setup then, and replace it with what?
The diode setup was simple, (and cheap)???
