*** Edited see new post w/ pics ***


Yesterday I was driving back home from work and the charge light on the dash came on while I was using the windscreen wiper switch and I noticed my tacho is going unstable keeps bouncing up and down from the idle speed
Battery not charging properly? My battery is kinda new bought it January this year
any advice will be great
thanks

I just found out that the "E" wire and bolt on the alternator broke off and was corroded, I took the alternator off now and will drill it out and put new ones.
its a good time to replace the brush as it near the hole marking
What else should I look out for while its dismantled.
I also have a '80 round headlight B310 Sunny A12 alternator... am I better off swapping them? just need to change my wiring right? not sure if its a Bosch or hitachi unit as its at my bros house getting it delivered soon :)
do sunny alternators have internal or external regulator?

the sunny alternator is Bosch
looks similar to this evilism's one...


back is similar aside from the round condesor looking one the sunny doesnt have it
any advice on fitting one of these?
its got "D+" "D-" "B+" & "+" on the back

just an idea but my tacjho did this in the coupe on its most recent electrical misadventure, turned out to be 3 blown fuses (at the same time) in the fuse box.
the tacho did this just prior to the fuses dying.... it appears for me t o be a fuse problem but check if your b310 alternatr has an internal regulator or not. if it does and you are running the stock external regulator... this could create issues similar to your problems.

the wire on my alternator broke off and the bolt as well thats why the charge light went on.
now while dismantling the alternator some more parts broke now I'm looking to get another stock alternator or put the alternator from my old sunny which is a Bosch item
just not sure how to wire it and havent tried fitting it yet been raining

How do you wire this alternator to a stock 1200 ute?
i think this alternator is off CA20 bluebird Bosch unit





my old alternator that decided to retire is a Mitsubishi unit



Can someone confirm this please

D- is earth
B+ is 12V to battery
D+ is Field
- is Neutral to charge dash light?

All is explained here: Wiring article in Tech Section.

I know which wire is which but not sure about the alternator side of it

D- is earth
B+ is 12V to battery
D+ is Field
- is Neutral to charge dash light?

once i know the markings of the alternator I can figure out how to connect it.

Anyone

i have noticed that when i have a few electrical somponents such as headlights, stereo and wipers that my charge light slightly glows or slowly flashes as power is drawn. is this normal?

check your wiring connection maybe your earth?
anyway
back to my question
can anyone advice me whats D+ ; D-; B+ and +
