the alternator??

My Scangague II started showing lower voltage on the way home Friday PM..
usually somewhere between 13.9 and 14.2 indicated and it dropped to 13.6 then 13.2'ish.
I made it home and put a multi gague across the batter at idle and was reading 13.2v.

before I go n order a new alternator is there another obvious case for under volting that I might have overlooked??
or how can i validate that the alternator is not putting out (enough) volts??

actually.. I have not checked if the earth is good.. whats the suggested method of checking?? I guess resistance from neg terminal to a point of the alternator body?

cheers in advance.

I suppose you'd be best cleaning the battery terminals and refit them to the battery and so on.

I'm sure I read somewhere that some cars are fitted with a so called "smart" alternator that drops voltage when the battery is well charged.

Might be worth looking in to before you buy anything!

Even early classics have that sort of alternator


Mine's 2volts below that and refusing to start at the moment. Get the alternator checked at a garage to be sure

OK sit down.

are you ready for this...??

called not so Subaru specilist n asked for price for alternator. 23700AA430
including half an hour fitting (40€).. 1178,63€

yes.. that 1138,13 for the alternator!!!
are they made of ****ing unobtinium or something

I will check the cables n connections tonight after work n then take the car to the local garage to get it checked, if it the alternator, I will be ordering it from Germany.. 150€ inc shipping.

THIS ^^ !!

You might have an issue, but before wasting money, at least trying reading the voltage with the headlights on and a little above idle speed.

What he said...could save you the €150 too.

should have said...
lights were on.. they always are, have to drive with main lights on here all the time or DRLs if fitted...

Im going to check the connections, cables and voltages again tonight with and without lights/AC/demister/fan.

also double check the battery light comes on with the key in IGN, as I know its NOT on when Im driving.

_Viktor

checked and I appear to have a bad connection between neg' cable and battery connector..
cable corroded (green)
so I will clean that up n get a replacement connector tonight..

cheers for input all.

Nice to know about cheap repairs for once.

Once clean and tightened, grease over the connectors to exclude water.

Good find, hopefully that'll be it sorted!
