GL1112 - Heavy Duty Wiring Kit for Fitment of Twin Alternator - By Gwyn Lewis 4x4 - For 200TDI and 300TDI

This wiring kit is to wire up your 2nd Alternator you have fitted, the main cable that goes from the Alternator to the Battery is 3mtr long and 25mm square, it is heavy duty, see picture 2 as it shows the cable against a pencil and a AAA battery to show how thick it is, it has everything you need to wire your 2nd battery and alternator.

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 Kit.
