Other comments:
I went to Honda parts to get a quote and they asked $485 for the regulator and $46 for the brush, I thought they were joking. Then I went to Ashdown in Sandown, got the regulator for $55 and the brush for $19.53. The conclusion is “DON’T BUY FROM HONDA PART” they are crazy.

just out of curiosity in what situation would u need to carry out this DIY?
good work btw =o)

[ram si]

yo my alternator is BROKE

if i did this would it work again?

or do i need to replace the whole thing

[Drew]

When the brushes are worn and the voltage is unstable as in it fluctuates between 11-16V in sync with the rpm

You should probably change the title to Alternator, regulator and brushes replacement rather than Alternation Rebuild... As you're not actually rebuilding or reconditioning it

So, what's the problem of you alternator, why you think it's broken ?

[ram si]

oh i was told by a mechanic that i needed a new alternator after he tested the battery with a multi meter.

yea i called honda for a new alternator and they were like "$2000 please"

i was like errrr i'll get back to you bout that haha

[Limbo]

try a reconditioned one its normally cheaper, i got one for a corolla for $120 with swap

[Bludger]

exellent DIY, after how many thou km's would you think they get worn?

wouldn't hurt to rp7 some moving parts???

LOL, just want to be picky

[EWCivic]

My car is a 85 EW civic, it has 204000Km on the clock.

[CanHonda]

would this make my 40inch sub thump harder ?

[ECU-MAN]

nice work

[EWCivic]

nice work

Thx, and a bump :D

[Bayani]

Are most Alternators interchangable?
Noticed someone put a reconditioned Corolla Alternator in..

[Bludger]

anyone know the part number for 89 ef crx?

If i call ashdown, and tell them my car, would they know?

[tiksie]

If only the Alternator were easy to get to on a EG GL :( ****ing most annoying place you can put it in! Hate HONDAS! FFFFFFFUUUUUUUUUUUUUUUU!

[ECU-MAN]

its not that hard,
if you fiond the right spot you can slide the altenator out.

my alternator is reading about the same as the OPers did before he replaced the regulater and (other thing).

would it be worth giving this a try before getting another one from a wrecker?? that may also be broken...

urgent guys,
please help

As long as the voltage output is the correct amount, or something like that. Search google if you want more info.

DIY.

I've had to get 3 from the wreckers and they kept screwing up so I ordered parts from Honda and I've done a DIY too that was to change the brushes. Good to change the regulator also. It's shit easy, most people are afraid they'll **** up their cars they start a new thread and chuck a hissy fit.

[paps02]

well i tried takin the alt off but i cant. its in a shit position (h22a in ej = bad) and waaaay to tight. and am worried about tensioning the belt too tight or loose.

how much for regulator and brushes from honda?? i was quoted $150+ by my mech

[sid]

I got brushes for ~$25 inc. delivery, same day delivery (Victoria). Honestly cannot remember how much a regulator would cost. Does the $150 include, removing/refitting/labor?

[paps02]

no :-( im lookin at a few hundred drive out

[EDCivic]

Just did ours this morning, and I reckon the bigger challenge is getting out. In the end after lots of swearing I found the right spot by ....

1./ Removed wiring from alternator and all mounting bolts as per diy article
2./ Removed the cast iron bracket that holds the base of the alternator in place to gain extra clearance.
3./ Dismantled the front half of the plastic gaurd under the wheel arch.
4./ Positioned the alternator so that it squeezed through the hub side of the front passenger wheel.

Cheers

[Bludger]

is it necessary to replace the regulator or just the brushes will suffice?

[EDCivic]

It depends how much you want to spend. I just replaced the brushes with an original complete set from Honda (no soldering, dismantling etc) for approx $40 and have had no charge issues since. If it was to be done by a Honda mechanic as I was going to in the first place he wanted to replace the reg as well. Cheers Ron

[Bludger]

yeah, money is an issue.
