NO
http://www.aa1car.com/library/2002/cm10220.htm The best way to test an alternator is to check otput voltage with all accessories turned on. Wipers, high beams, ac fan, rear window defroster, etc. Voltage should stay above 13V
Positively positive
get a multi meter that reads dc voltage & touch the black (negative -) wire to the negative battery post & the red (positive +) wire to the positive battery post with car running. car off is battery voltage, car on is alternator voltage.
An alternator and battery hookup diagram typically shows the alternator connected to the battery with two main wires: a positive wire from the alternator's output terminal to the battery's positive terminal, and a negative wire from the alternator's housing to the battery's negative terminal or ground. Additionally, there may be a connection from the alternator to the vehicle's electrical system to power accessories. It's important to include a voltage regulator in the setup, which controls the output of the alternator to prevent overcharging the battery. Always ensure proper wiring to prevent electrical faults.
battery and or alternator are shot, check alternator by starting the car, and removing either the positive or negative battery cable,,, if the vehicle continues to run the alternator is good.
An alternator has diodes which transform ac voltage to dc voltage so that the battery gets negative and positive current on its poles thus making the battery to be charged.
You do not connect any wire from the alternator to the starter. The positive wire from the alternator should run to the positive on the battery, and the negative wire (if equipped) should run to the engine block (or any suitable ground). Most alternators are already grounded by the bolts holding them to the engine, but some do have a negative wire.
No, not the battery. But anything that has a diode, transistor or is in any other way dependent on polarity may be fried... including your alternator.
To hook up an alternator in a Chevelle, first ensure the battery is disconnected for safety. Connect the positive terminal of the alternator to the battery's positive terminal, and the negative terminal to the car's ground. Then, connect the field wire or the voltage regulator wire to the appropriate terminal on the alternator. Finally, secure the alternator properly and reconnect the battery before testing the system.
1. Remove the bolt retaining the negative battery cable to the alternator adjusting bracket, if so equipped. If not, disconnect the cable from the negative battery terminal. 2. Disconnect the cable from the positive battery terminal. 3. Disconnect the 2 electrical connectors from the rear of the alternator. 4. Remove the bolt retaining the alternator to the adjusting bracket. 5. Remove the alernator pivot bolt and remove the alternator from the vehicle. 6. Installation is reverse of removal, noting the following: 7. Reconnect the positive battery cable before reattaching the negative cable at the alternator bracket. 8. Adjust the alternator drive belt.
Disconnect the battery negative terminal. Remove serpentine belt. Remove bolts to alternator and positive cable at alternator and harness. Remove alternator. Reverse procedure to install.
Remove the bolt retaining the heater hose clamp to the alternator adjusting bracketRemove the bolt retaining the negative battery cable to the alternator adjusting bracketif equipped if not remove the negative battery cableDisconnect the cable from the positive battery cableDisconnect the two electrical connectors from the rear of the alternatorRemove the bolt retaining the alternator to the adjusting bracketRemove the alternator pivot bolt and remove the alternator from the car
run it and then disconnect the negative wire from the battery if alternator dies its bad.
