Evening

I found my battery completely flat tonight and after several helpful posts on fault finding techniques i believe i know the problem

Here are some posts from flange nut on the subject

The Vicky Green loom uses Brown as the unswitched live and Green as the switched live. White is the ignition live.

I have a Vicky Green Loom and a Nippon Denso alternator. The problem is that the field coils of the alt are permenantly connected to the battery (thin brown wire). I had to modify my loom to use a switched live feed.

Being an electrical fool this means very little and i don't know how to rectiy the problem. I've U2U flange nut for assistance though any info from anyone else much appreciated.

Thanks
Nigel

i got a wire diagram for a toyota 4age alternator which i believe to be a denso unit, il try and get it uploaded for you.

Hi Nigel,

Not sure if it's exactly the same alternator, but definitely a Denso one so these pics may help....

Thanks for the help

Nick with it wired as it is did you have any problems with battery drain? That's how mine is wired and the battery flattened witihn 4 days.
did you have to modify the loom at all?

Thanks
Nigel

get a 12v bulb, a piece of wire,

remove the positive battery lead

connect the bulb to the positive lead and to the postive terminal on battery

if the bulb lights something is draining current.

to work out what is drawing current disconnet each component in turn.

Nigel,

I don't recall making any mods to the loom for the alternator wiring. Although I did wire it up incorrectly at first which caused a current drain - IIRC I had the charge warining light wired up wrong somewhere along the line.
