: My son has purchased a 1990 Honda Accord - alternator light has come on and we're just trying to remove it to have it checked.
: Haynes has us removing the pivot bolt and the adjustment assembly, but it won't budge. Looks like there may be something like a pin that goes on the rail that is sloted, but I see no way of removing it.
: Any suggestions would be appreciated.

 

when you say alternator light, is it a battery light that is shining?

 

Just checked with my son - it is indeed the battery light.
We had replaced the battery about a month ago and when it died we took it back and they charged it up and put a load on it.
When we restarted the car the light remained on.

 

ok, so the problem is your charging system. the car is running off the battery right? like it'll die on him, correct? either it's a bad battery, or a bad alternator. a easy way to check if it's the alternator is to disconnect one of your battery posts( i prefer the negative) while the engine is on. i always did that if i had a problem, but people on this site would reccomend you take it to a shop............sorry i don't have a 90 accord so i can't tell you how to disconnect the alternator.

 

be careful when disconnecting te batter posts. Doing that will cause the alternator to open up to it's full capacity and that will mess it up. Take it too a shop.

He knows a lot about these cars.

ok, here goes:

there's the pivot bolt on the top of the alternator holding it onto the bracket.

the adjuster system is under the alternator. there's 2 bolts on the front when looking head on at it. the right is the adjuster bolt, the left is the adjuster bracket bolt that stabilizes the adjuster bolt. on the right side of the adjuster bolt, you'll see a lock nut.

disconnect harness and ground wire.
loosen the pivot bolt up top.
remove the locknut from the lower right side of the adjuster. loosen the adjuster fully and remove the bolt.
remove the adjuster stabilizer plate by removing the bolt to the left of the adjuster bolt.
fully remove the pivot bolt and rotate the alternator downward to remove the alternator belt.
rotate alternator top towards you to pull the alternator away from the top of the bracket at the pivot point.
slide alternator to the right to clear the guide pin from adjustment arm and the alternator should be free in your hands.

there's an adjustment rail on the bottom of the bracket where the pin the locknut is guided by... the pin doesnt need to be removed, but you have to rotate the top of the alternator out of the pivot point first so you can slide the alternator to the right to get the pin to clear the adjustment rail for complete removal.

 

NICE!..good Explanation!

 

: Thanks for the great tip!
: We got it off.... finally - guess what - it tested ok.
: So it goes - back to the trouble shooting guide.
: THANKS FOR EVERYONES HELP!

 

Check the brushes... If they are worn down too far, Murphy says they'll make good contact when its on the test bench. Then you'll put it back in & it won't work.

Or maybe there was a loose connection that's gonna be tight now that you've had it out & back in. Corrosion inside the crimped connections of the power leads can do funny things.
