Hi all.

Had a problem with battery light flickering. Checked the alternator and there is a single wire that has been cut. It's marked D+ but cannot figure out for the life of me where it connects.
Can anybody please explain or got a pic of where it should go. I've got a Rs mfi engine.

Thanks

 

d plus is the warning light circuit should be a blue wire goes up to the dash bulb alternator only has three connections at most would be easier if i knew what alternator is fitted to your car ie is it bosch lucas mitsubushi

 

What he ^^ said, without this you will have no charge, this excites the field windings that starts the charge process, it's the earth from the warning light, when charging thats why the light extinguishes as two lives(It would charge if revved hard enough as well) It's just snapped as they commonly do you should find the connector on the back of the alternator still. Best bet is to use a ring connector and a nut and use another piece of wire to connect again to the blue wire.

Thanks for your replyS. I have managed to find the other end. It had gotten caught in the belt and ripped and hidden. Replaced the wiring and seems ok now.

 

Just in case it might ever be useful, if you tap a 12v feed onto the D+ it will start charging if engine already running, not needed after this, saved me grief a few times on hols with mates, just crawled under car wrapped wire and taped up and the post a wire that went in the car, used to plug into ciggy for live whilst starting then unplugged.
