Should a cable running to the alternator be live?
Yes This Cable Is Connected To A Group Of Cables That Run To The Battery Positive Side, To Allow The Alternator To Charge The Battery.,Do Not Remove Or Install An Alternator Until You Remove The Ground Terminal From Your Battery.
Why would the alternator in your 1994 Mitsubishi galant not be charging the battery when it is not defective?
usualy if the alternator is not defective then its the battery. you should start by cleaning the battery post. then you could check the terminal wire that runs from the battery post to the alternator. if thats not it you should check the ground on the alternator.
What could cause voltage to drop when alternator is new?
The ground cable, on the battery may need to be tightened or cleaned. The alternator voltage regulator may need to be replaced.
Where is the alternator fuse on a 2007 Saturn aura?
The 07 Saturn Aura does not have an alternator fuse, and technically it is a generator not an alternator. There is a large gauge wire from the generator to the starter, this is a fuseable link. Check for 12 vdc at the large terminal of the generator, if is missing check the terminal on the starter. If the starter has 12 vdc and the generator does not, the link is bad and must be replaced. DO NOT REPLACE the link with wire, a fuseable link must be used.
What has happened to the electricity if the battery cables were not disconnected before the alternator was replaced?
batteries are stored energy, nothing should have happened. They say to disconnect the negative terminal for safety reasons.
How do the wires hook up on an alternator?
Typically, the alternator has three connections. One is the ground, which is provided by the bracket that you bolt the alternator to. Second is the main power terminal, and is connected with a bolt to a high power cable that goes directly to the battery. CAUTION: Make sure you disconnect battery ground before you put a wrench on the alternator stud, just in case you touch ground while turning the wrench. Third is a two or three pin connector that goes to the harness, providing regulator power and connection to the warning light. Some older alternators have an external regulator, and they will have a smaller bolted connection to the regulator. Its easy to see which is which, due to the terminal size.
Can an internal voltage regulator be replaced on a 1996 jeep grand Cherokee or does the alternator have to be replaced?
The regulator is in the engine computer not the alternator.
What does an isolated ground mean on a 12 volt alternator?
This might mean the ground is isolated from the case of the alternator. In a normal application, the case of the alternator is the ground connection and being bolted to the engine block via a metal bracket, the grounded case of the alternator is electrically connected to the ground lead of the battery which is also connected to the engine block. An isolated ground might indicate the alternator ground is electrically insulated from the alternator case.
Is the negative terminal the ground?
yes the negative terminal is the ground. also it is the black lead that goes to it
How do you change the alternator on a 2005 Mustang?
4.0L Engines V6 # Disconnect negative battery cable # Remove alternator drivebelt # Disconnect the electrical connector from the alternator # Remove the rubber weather boot from the alternator B+ terminal nut,remove the nut and disconnect the battery cable from the B+ terminal # Remove the nut from the alternator mounting stud,remove the two alternator mounting bolts and remove the alternator 4.6L Engines V8 # Disconnect negative battery cable.Remove the air intake duct # Remove the four alternator monting bracket bolts # Remove the drivebelt # Remove the two lower alternator mounting nuts from the mounting studs # Tilt the alternator forward to access the electrical connectors on the backside of the alternator B+ terminal nut and disconnect the battery cable from the B+ terminal,then disconnect the electrical connector from the alternator
How do you replace the alternator on a 2007 mustang v-6?
* Disconnect the neagtive battery cable * Remove the alternator drivebelt * Disconnect the electrical connector from the alternator * Remove the rubber weather boot from the alternator B+ terminal nut,remove the nut and disconnect the battery cable from the B+ terminal * Remove the nut from the alternator mounting stud,remove the the two alternator mounting bolts and remove the alternator
Installed alternator and went to hook up battery and got sparks from negative terminal and alternator?
wires are crossed or you have a short in the wiring from the alternator to the battery.
