Anyone used one of these nice small nippon denso alternators ?

Presuming the 3 pins are ign live/charge light/earth

BUT which is which ?

any clues lads

nice pics bob,i bet the terms are marked P/IG/L


bob - 26/11/06 at 02:30 PM

part no of alt is 16678-64012,terms are marked
P IG L if that means anything to anyone


bob - 26/11/06 at 02:32 PM

You should know as the alt is in your hands.

I'll take a wild guess and say IG is ignition and L would be charge light so is P earth or does it earth on bracket ?

let me know when you find out bob, i've got one of these to fit with the same miniature connectors..

I believe P is probably permanent live.
There are some wireing diagrams here
http://westfield-world.com/daihatsu_alternator.html
but none have exactly the same connector.

i'd be more concerned with the footwear in the photo

No prob ned,the alterator is conrods but he cant get the pics to upload.Although i must admit they are a very nice compact unit.

nowt wrong with my footwear

Looks like P is permanent live then.

Many thanks for the link ian

Link seem pretty much spot on.

Mine is the three terminal type, IG is the ignition live that make the charge circuit work and L is from the dashboard light which also has an ignition live to it.

I tried wiring it with a permenant live from the "B" post but didn't like the idea it was "always on"

I'd go with the first diagram for the 4 terminal version with no perm live.

Earth is via the block as usual.

Do you mean the charge light stayed on all the time? If so something definately wrong there!

The P terminal is a remote sense wire to allow the regulator to measure battery voltage more accurately, i.e. it eliminates the error due to voltage drop in the main battery cable.

Just got one of these alternators.

Fits perfectly, the bracket from the Swift even fits the pinto.

But cant get it to work. Used the previous link to the westie website. Mine has 3 pins and have tried the first method as the plug i got with it only had 2 wires.

Ive tried connecting the switched earth but not getting over 12.60 across the battery which is the non running voltage too.

I havent wired up the light yet, so havent connected that wire. Do you need both to make it work? On my last alternator I just had the + feed connected and it worked fine.

Any ideas before I go back to the scrappy and get my money back.
