My friend wants to install a second battery in a diesel BT50. The local auto tech advised him that the new BT50 had a "low output alternator" which could affect the operation of a second battery.
IF any member has a BT50 with a second battery, could you please MM me with details.
Thanks for any info.
Cheers.
Vince

Have just finished wiring
mine today without any drama's.
Simply an isolator next to main battery 14mm square cable to deep cycle in tub.
Fridge, recargeable maglight, invertor and bank of 12v outlets all work no drama's. .1v voltage drop through system.
I think the rumour about low charging voltage's is a complete myth, I never seen less than 13.9v's on
mine whether city or highway driving. It's funny how people believe these rumours, how is your main battery going to charge at 12.5 volts?
Just make sure you take both positive and negative battery to battery.

Are we talking about the NEW BT50 with the 5 cylinder diesel and 6 speed trans?
The new ones us a very smart charging system and yes 12.5v is about it when under no load.
The battery charge voltages are getting lower and lower all in the name of emissions and NVH.
Many are complaining of flat battery's and the dealers (Mazda and Ford ) know about it.
