Autozone told me that my wiring for my 93 buick regal was messed up on my alternator I thought my starter was killng the battery so I had them test it but that's when they said its the wiring to your alternator.i bought the new one took off the old and replaced it just like i took old one off why am i having wire problems?? no i didnt mess anything up pls help

loose or dirty connection to alternator wires ?

i would check the wiring from the ignition. and the wiring to the starter.

the b side of the relay is battery side the s side is starter side.

In front of the oil pan. Follow + wire from battery.

The gauges fuse under the dash powers the idiot lights and gauges.If they are working, you need to check the fusible links.Disconnect the battery then look at the starter.The terminal that the heavy battery cable bolts to also has 2-3 other wires bolted to it give each wire a moderate pull,if any stretches easily the link is burnt.When a large short occurs the link will burn out but the insulation usually still looks fine.Make sure to replace it with the same size fusible wire.

ck.by the starter ,wires leading to starter.

When my 94 Regal GS frequently wouldn't start for 30 minutes to an hour after being driven, it was the crankshaft positioning sensor that needed to be replaced.

no the crank shaft sensor would not stop it from turning over

Connect a volt meter to the neg. and pos. of the battery. Have an assistant start your car and watch to see how far the voltage drops. If it drops more than 2 volts, for example, hook up the meter, you should see 12 volts. By starting the car and it drops below 10 volts during start up, your starter is slowly going out. It taking more amperage to start it than normal.

the voltage regulator is internal on that alternator. Take the alernator back off and take it autozone or advance and have them bench test it to see if its good or not. That model car doesnt have a fuse for the alternator either and the regulator is internal on that model. Thats a standard sg gm alternator. those above stores do not charge for testing it for you. another quick way if you have a volt meter is black end of volt meter to the negative battery cable and the postive end of the meter to the thick red wire on the alternator that you had to put the nut on. then with car running that should show 13 to 14 volts. If not, suspect that alternator. But try the free check on it before going through too much more grief with that. if you had it tested. take the whole car to the autostore and ask them to check it while the car is running, Autozone and advance both have the machine they will take out to the car and check it for free. Otherwise, get a volt meter and check it as I said. If the alternator is putting out, then you have a bad cable or the 'field' wire is bad.
