2 hours needed to change alternator:
- disconnect battery.
- remove top covers of engine - behind front seats
- remove 4 plastic bolts to remove side cover.
- remove all of the bolts to remove metal cover
- losen belt by putting a 24mm wrench on tensioner and turing CCW. You should also consider changing the belt ($18)
- remove the alternator screw and the flywheel screw beside alternator.
- move the alternator up on the flywheel screw side. If stuck use a hammer and wedge to move it up until it losens.
- remove wire and plug.

Rebuilding the alternator. Only 4 things can be wrong:
1- bearing worn out - turn rotor to test.
2- coils short - smell and check for burning in side.
3- Rectifier - take plastic cap off and test with an ohm meet from the heat sink to each of the 3 diodes, then reverse the testing points. If both resistances are the same on any of the 3 diodes, replace rectifier.
4- If the top 3 are fine, then it is the regulator. This is a hard part to find retail. Ebay and other sellers will try and get over $100 for it. Porche claims they don't sell. I found it a wholesaler, who I begged to sell it to me. Cost C$17. 2 bolts and one screw and 5 minutes later and it was replaced.

To reinstall follow the reverse. Remember the flywheel part of the alternator goes in on the to of the backet. you may have to use a hammer and wedge to get it down. Install the flywheel before it goes all the way down, or it will be difficult to slide in.

Enjoy.

To gain access to the alternator you have first disconnect your battery. After that you need to remove the passenger seat. Then remove the engine access cover and you will be able to remove the alternator and belt.

I need a rectifier as well since I have AC current leak peaking around a full one volt. This makes my radio cut out at higher engine RPM. Where do you get this part in lieu of replacing the whole alternator?

While driving down road my kia 2002 spectra just died and now when I turn key it just clicks and all the dash lights and radio go out


was there any warning lights before dieing ?it would seem to be an alternator/charging problem,is the serpent belt ok? try jump starting or changing the battery, if she starts then check for ignition charge light staying on, if she still wont start/turnover could be a starter motor problem or a jammed alternator, if she wont turn over on a fully charged battery or jump leads remove the serpent belt that drives the alternator/AC /power steering etc try starting again if ok switch off and try turning each pulley driven by the serpent belt by hand the only one you should not be able to turn is the main crankshaft pulley, if any of the others are hard or impossible to turn you have found the problem

My 83 camry died one day on my way to school. I noticed that while I was driving my lights started diming then the engine just shut down. Found out that my alternator was dead. In your case have your alternator tested, your battery charged and check to make sure you have the belt that turnes the alternator and note if there are more than 3 cracks in the ribs of the belt per inch, I would replace the belt while you have the alternator out.

I have a 2002 porsche boxster and the dash light will not turn until I lock the door manually.


This is a problem with Porsche cars. What you need is a trickle charger or use the car on a more regular basis to keep the battery charged. If you have a garage with power get yourself a trickle charger and leave the battery on charge when not using the car. If this is not posible charge the battery up fully start the car and see if your dash lights go out. If they don't go off it might be your alternator is not working, get it checked out, or do it yourself if you can.

Not a sensor or fuse. Possibly the battery: only way to know is have it checked. Best way is check when car wont start. Should have over 12 volts. I would suspect alternator is not charging battery. Put a voltmeter on battery when car is running. Voltmeter should read 13.5-14 volts. If not, something's not right. Check your battery grounds for tightness and cleaness. Sometimes a loose connection will keep battery from either charging or starting. If you still have the problem, check your starter for a short, drawing too much amperage.

Sounds like your engine cut out. Check your battery condition and your alternator condition.

Battery light came on,no power steering.Tried to drive home,ABS light came on,wipers were slow also.Pulled in,car wouldn't start again.


It is most likely your alternator. Your alternator failed and then your battery lost its charge. Have the battery charged and tested before you replace anything just to double check. Either way, the battery needs to be charged seperately. Don't try to charge it with your new alternator or jumper cables as this could burn up your new alternator.

2003 kia optima battery light came on and headlights went dim and then out but high beams still work, dash lights are dim and the car still runs.


The alternator has stopped charging for some reason.
First check alternator drive belt is ok;
Check dash 'battery' (or 'ALT') light illuminates when ignition on and motor not running- if not, check 'ALT' lamp is not blown and connections to alternator are ok;
If all above ok, the alternator may be faulty.

It's the power steering, altinator and water pump belt. It is also held in place with two plastic tensioners on a V groove belt. The Pop, or bang, you heard was the belt comming off the drive mechanism. The belt may not be at fault. The tensioners give up from time to time so you would be better advised to ensure that the tensioners are still in operative condition before you replace the belt. The belts are about $200.00-$250.00 a shot, so you'll be wasting your money on just replacing the belt, without having the tensioners checked. I am not sure what engine is in you Boxter, if it's belt or chain driven to thecam, belt I would have thought, so it would be cheaper for you in the long run to have the both belts changed at the same time. it's false economy not to do so. take your chance if you want.
