Alternator wiring plug?
Got a replacement alternator of the same size and type of that it is replacing except its from a different donor (kubota as opposed to charade) and it
has a different wiring plug. The connections are labelled 'P', 'IG' and 'L' the previous one only had two
connectors, ignition and lamp which I'm assuming is what the IG and L are for. So what is the P for, do I need it and where can I find a plug to
fit it as the terminals are too small for the spades I used on the previous one.
Here is a pic of a similar alternator to illustrate the connector type, it doesn't look like the standard bosch type connector, guessing some
small jap/whatever nippondenso use type?!
cheers,
Ned.

I would take a guess that the 'P' is for a positive feed, or maybe a voltage sensor (if the 'IG' isn't)
I've got a similar issue with my Denso alternator which I am still trying to figure out properly.

Ned, have you tried Vehicle Wiring Products for the connector and terminals - they're normally pretty helpful with stuff like that. My
alternator came from Kubota tractor engine too, but sounds llike the one you are replacing as I have been able to use spade terminals to connect to
it.

Hi Nick,
Yes most of the kubota/nippon denso models just have two normal spades set at 90 degrees which are easy to wire too. This also confused me as to why
this one has 3 connectors as the last one was identical bar the wiring terminals and onyl had 2 terminals on it.
I have a copy of the VRP catalogue on my desk but they all look like bosch connectors in there, none of them look 'right' to me. 
cheers,
Ned.
I think i'll get a better pic of the connector socket tonight which might help.

Pretty sure you do not need to connect up P. I use a denso with 3 pins and have never bothered connecting it up with no ill effect. The connector
looks similar to the one I fitted which is an AMP connector. The AMP part number is 6189-0442 for mine and you may be able to check if you go to the
AMP connector website and look at the drawings of the connector.

Here's a close-up of the connector on the alternator:

I hadn't realised how much smaller the new alternator is compared to the charade one that is broken!

Ned, those terminals look as if they might take the very narrow crimp-on spade connectors

Sorry fo the delay, I only seem to get on here during my dinner these days.
Appologies for the part number, the one I gave you is for a full assembly and not shown on the website. The part number should have been 174357-2.
See the link below
174357-2
The connector is a Tyco/Amp Econoseal J Mark II+
If you look half way down the page on the left where it says " Product drawing " the link will open a engineering drawing in PDF
format.
Hope that helps.

thanks for the link silex but looking at the pdf I'm still not sure it would fit, it looks a better match in the catalogue pdf than the
individual one Any idea where I can order one from? I'm also going to order some 2.8mm spades from vrp and see if they are anywhere near
though I think they might be too large.
cheers,
Ned.
