You are just learning. Honda designers had to find something that would even fit in that little bitty space. Many auto makers use other brand's products for different reasons; Size, performance,life expectancy. TV and radios are now throw away. - buy another. Cars may be that way one day.
around 14-14.5 volts
You will have to use an Easy Out to remove the old broken bolt.
Autozone says it's an 80 amp alternator. I don't know if this is the max it should put out or the average. I'm guessing the max.
Have you drove the car around? Sometimes it takes the alt. awhile to "kick" in. Say around the block twice?
My advice is to charge the battery with a battery charger before starting the engine. You will be putting a heavy load on the alternator if you allow it to charge a dead battery. This could damage the alternator.
Loosen the upper and lower alternator mounting bolts. Turn the adjustment bolt on the lower left-hand side of the alternator. You should only be able to bend the belt 90 degrees at its longest run, in the middle. When done adjusting, tighten the upper and lower alternator mounting bolts.
The most likely cause is the voltage regulator in the alternator. Modern vehicle voltage regulators aren't serviced separately, so you would just replace the alternator. That much voltage can boil the battery. Typical alternator output should be around 14.5 volts.
It SHOULD put out between 12 and 14. If you're getting 18 it means your voltage regulator is fried. Less than 14 and the alternator itself is cooked. Either one requires a trip to the auto electric shop to fix.
There are a lot of issues one should look for before buying a 94 Honda Accord because no company is producing this kind of product any longer. Therefore, checking the engine is one of the most important issues.
before you do anything with the alternator, make sure to unplug the battery. Then unplug the cables going into the alternator. There should be two. For the belt there is an engine part called a pulley - lift the pulley upwards to loosen the belt and take it off the alternator. Next you can unscrew the bolts attaching the alternator and take it out.
IT SHOULD BE UNDERNEATH THE CAR BEFORE THE MUFFLER(ABOUT THE CENTER OF THE CAR) JOSE
It should put of 13.5 to 15.5 volts. The alternator is an 80 amp alternator.
