Is the battery light on with the key on, engine off? if not.... it should be. if not, one of the small wires is the ground for the bulb. if the bulb is burned out, it wont charge....The large wire should have 12volts. What is the voltage at the battery when running?

I replaced the altenator and voltage regulator in my 1980 ford f 150 and it still wont charge the battery

alternators need current imput to generate current. Check if there is current coming to the connector atatching to the alternator socket. If there is no current, check the "alt" fuse or wiring. Charlie

I am having a problem with my alternator. I have been told there is a fuse that will interupt the charge getting from the alternator to the battery. Is this true and if so, which fuse would it be?

you can have your altenator tested at an autozone,advance auto for free while it's still on the car,or you can check it yourself by starting the car,while running disconnect the positive cable,be careful not to let that cable touch anything. if the car dies,the altenators bad. as far as a fuse, you may have a fuseable link,but those are usually for the starter.someone may have done some other wiring to it.i would check the altenator first though.also make sure your belts tight and the altenator is plugged in. check the plug on the altenator to insure it's plugged in all the way.make sure your battery cables are tight. if you decide to go to a parts store to have the altenators good,have them check your battery also. it's free.if your car runs fine until you park it at night and then next morining it will not start,it may be bad battery.just thought i would throw that in,just in case.hope this helps and thank you for choosing

The altenator will not charge the battery on a 1996 mercury mysti

Check the small wires that clip into the side of the alternator, they set the Field coil in the alternator and could be causing the issue. Also, how old is the battery? If it's bad the alternator will cook the voltage regulator because it will be at max out put all the time.

1988 wagoneer electrical issue

I believe that your headlightsw are powered by a fusable link, likely connected near the alternator or battery, I't's possible that the wire may have dropped and did not get re-connected when you installed the alternator, or it was weak and failed while you were working.. I don't see why it would cause the aternator to not charge but either it also completes the battery circuit or there is a second wire.

1995 Jeep wrangler not charging properly

lf you have replacement cable ends on your battery, check that wires are not corroded under the straps. Also check alternator ground (run a ground wire directly to the alt case) I have seen "lazy" regulators at times but this is very rare. Also make sure drivebelt is tight enough to prevent slipping. Has your battery been charged and load tested?

Elec problem between alternator and battery

Rest at ease the 14 volts will not hurt your system idealy your alt will charge at around 14 to 14,5 volts at the alternator and probably have a slightly lower charge rate at your battery at around 14 to 13.5 at the battery this is completely normal

Charging system

3 wires for the altenator all controll the voltage regulator. You need the ground as said and one is 5 volt constant and the other is 5 volt switched.
