Default Split Charge Relay in Transit Van

Hi there,

I have a transit van home converted to a weekend surf van. I have a
seperate battery in the back which runs the lighting etc. I have
brought a split charge relay but am unsure of where to pick up relay
energiser from the alternator. Looking at the top of the alternator
there is 3 wires, from left to right a big wire running to the +ve
battery then a smaller blue wire running into the loom, and a white
wire also runing into the loom. I have no haynes manual so do not
know which is the right wire. I have been told that the blue wire is
the one to go for, but it looks small so I am not sure if it is the
right one. If anyone had fitted a simular system to an M-reg transit,
could you confirm that this is the correct place to take a feed. I
have also heard that you can take a feed from the back of the
instrument cluster, is this easier.

Cheers

Trev

I think from memory its the battery warning lamp wire that you connect to.

Hi Trev,

The blue wire is correct. It is only a sensing wire. However, it is
simpler to fit a voltage sensing relay which requires no switching wire at
all.

If it's the sense wire, that's not the one. The sense wire is connected to
the battery. It senses the battery voltage and draws almost no current. The
alternator maintains this terminal at it's specified voltage, normally 13.8
to 14.2 volts. Using remote sensing, compensates for the effect of any
voltage drop in the main alternator output wring.
Test the alternator, Two of the wires should be permanently live. The one
that you want is the other one. Alternatively, connect to any ignition feed.
