Alternator Wiring Volvo 460

Sep 18th, 2006, 07:49

Good Morning.

Hi mines a 460 td 142,000

I think we found the problem with my battery dying we have changed the alternator. But found two spare cables i have all the correct ones on B+ and B- But we are left with another two maybe these came off the old one and that is why it was causing problems as they were not attached?.

one Brown And Blue goes to W or M lowest bolt?. But we are left with a Black and White do not know if this is spare or if it should go somewhere?

If some one knows or could have a look it would be appreciated.

Hi there,

The brown and blue wire is connected to one of the alternator housing bolts amd the white and black is the connection for the oil pressure switch on petrol cars (may well be the same on your diesel) It earths the oil pressure warning lamp on the dash.

The following should make it clear.

Hope the above helps,
Mollusk.

Many thanks

for the pics really helpfull got to work the differences out but understanding the loose cable left will really help i have changed the alternator and left the one wire off at moment, The black and white one.

Does any one know what the W stands for on an Alternator as at the moment i belive i have an earth cable attached to it at the moment

Also got an earth to B- Then Main cable to B+

So Red to B+
Brown and blue x 2 one To B- and one to W?
Black and white (oil Pressure earth?) to go to W?

Hi

see attached diagram, apologies as its not in english. It came from this site

http://volvo.ic.cz/

they have pdfs of the 440 manual and wiring diagrams

diagrams are at http://volvo.ic.cz/elektro/elektro.html

diesel info at http://volvo.ic.cz/volvo440_d19t/volvo440_d19t.html

language is a problem, but most links show an english url in the status bar when you hover over them.

the brown/blue connects to the W terminal which supplies a signal to drive the rev counter. This is different to petrol cars.

Hope it helps

Many thanks that is the most detailed manual yet for the d19t It should have a place on the site unless it already has. If any one knows if it does or does not is extremly helpful
