1 x Twin Alternator Mount & Fan Belt (300 Tdi Defender, Discovery, RRc engines) .
This mount allows a second alternator to be fitted to charge auxiliary batteries instead of a split charge system.
An original 300Tdi 12 volt alternator can be fitted or we can supply a
high output 12 Volt 100 Amp A127i YLE10113 with 7rib 65mm pulley.
We recommend using an A127i Alternator, these
have an internal
cooling fan blade, an A127 Alternator has an external cooling fan
blade which can fowl on the tensioner arm of our mount, an unshielded
external fan blade could also be a hazard.
This mount fits in the position of the air con pump and is supplied with a fan belt.
For use in expedition vehicles or in any vehicle where you want to power auxiliary equipment using a second battery, up to more extreme use where you need to maximize charge current on winch challenge vehicles.
What you must remember is your batteries are just an electric storage tank, it’s the alternators that do the hard work, the quicker you can charge the batteries the more power you will have, even with a split charge system you still only have one alternator supplying your electrical system.
The Benefits
Two alternators using separate charging circuits are far better than a
split charge system run off one alternator.
Most split charge systems are basically just a switch
that automatically joins your batteries together in parallel once you start
your engine and your main battery starts receiving
Battery Maintenance
An alternator in normal use will replace charge that
you are using, it won’t charge your batteries up to full peak charge, to do
this you need to use a specialist mains powered maintenance trickle charger
that will slowly and gently charge your batteries up to peak capacity. This is
particularly important with batteries like Optima Yellow tops, they will take a
lot of abuse, they can be deeply drained of charge but they must be properly
recharged back up to peak capacity after to avoid premature failure. This can
only be done by using a slow trickle charge, an alternator cannot do this on
its own, it can take a day or two to fully recharge a heavily discharged deep
cycle battery using a specialist trickle charger.
Wiring :-
The kit is supplied with a wiring diagram and this
can be download in my Fitting Instruction.
Earthing the alternators is very important in my
opinion, this is how you get maximum charge out of your alternator, high output
alternators can’t always earth properly through the bolt holes, I even earth
the standard alternators as the mountings are bolted to a painted engine block
and rust and corrosion over the years will cause a poor earth.
What you must remember is the batteries are just an
electric storage tank, its the alternators that do the hard work, the quicker
you can charge the batteries the more power you will have, this is why my
alternator wiring kits are very heavy duty as well.
Fitting a relay as a secondary ignition is important
in my opinion due to you having 2 wiring circuits so it keeps everything
separate.
All this can be found on my Alternator wiring kits.
