I am trying to install an alternator in a 1992 Acura Legend. Someone took it out for me and it looks like he disconnected a wire from somewhere other than the alternator, but the wire appears to be part of the wiring harness that the other two wires for the alternator. Can anyone tell me where that third wire is. It's not the battery cable or the four prong connector.

If you lean into the engine compartment from the passenger side to look at the pully side of the alternator, you will find a bolt (10mm I think) sort of behind the alternator and to the back left. It is sticking straight up, and you can use a nut driver or ratchet to turn it counter clockwise to loosen tension and lower the alternator. But you have to loosen the locking bolt first. When you look at the pully side of the alternator (once the plastic shroud is removed to expose the belt and pully) you will see 2 large bolts (one on the bottom right and one on the bottom left) on the alternator that hold it in place. The one on the bottom left (on the same side as the tension adjusting bolt) is the locking bolt. You will see that there is a track for it to slide along as the alternator swings up and down. If you loosen this bolt, the alternator should be free to swing down on the left side when you adjust the adjusting bolt. However, it is common for the alternator to stick even after you have loosened the locking bolt and . When I adjusted mine, I had to remove the bolt on the bottom right because my alternator had been in there so long is was stuck in place. (The alternator is supposed to pivot on the right bolt, but sometimes it sticks.)

check the brushes inside the starter motor they may be jamed or worn

SOURCE: 93 acura legend just replaced alternator and

I f the car turned over before you replaced the alternator then maybe the problem is not the alternator but ignition issues, sometime the igniton module goes on these cars without warning my advise would be to remove one of the spark plugs to check for spark, remove wire then plug in plug to wire lay the plug on a part of the motor that is metallic, have an assistant turn the car over and try to start look to see if plug has a blue spark or purple don't do test in direct sunlight. If a good spark is seen go on to next test stick your finger into the hole where the spark plug goes have an assistant turn motor over you should hear and feel alot of pressure trying to push your finger out of hole if you don't feel a good deal of pressure you probably broke the timing belt and the cylinder head must be removed and rebuilt because of the nature of the designed interference engine (valve gets hit by piston bending it when timing belt breaks) good luck
