Getting to the point of what you are saying, the problem would be in the alternator and a diode.

How to jump start a vehicle safely


You have a dead battery and need a jump start. There is the right way and the wrong way to accomplish a jump start safely. Because of the potentially severe hazards due to improper use of jumper cables it must be done correctly. Auto batteries contain Sulphuric Acid which can blind you, or at the very least burn your skin. Also auto batteries vent off Hydrogen Gas which is highly explosive even from the slightest spark. Because of this danger it is critical to attach the jumper cables in a precise sequence. 1. Park the vehicle with the GOOD battery close to the vehicle with the BAD battery but do not let the vehicle touch each other. Make sure the cables are not routed so as to touch any moving parts, such as a fan blade. 2. Attach the jumper cable Positive + terminal to the GOOD battery Positive + terminal. 3. Attach the other end of the jumper cable Positive + terminal to the BAD battery Positive + terminal. 4. Attach the Negative - jumper cable terminal to the GOOD battery Negative - terminal. 5. Attach the last jumper cable Negative - terminal to a heavy metal ground part of the engine and NOT to the dead battery Negative - terminal. Reason being this last connection will cause a spark, and you do not want a spark next to the battery where it could ignite the Hydrogen. 6. If the engine of the donor vehicle with the good battery was not left running, start the engine and let it run for 2-3 minutes to put a charge in the bad battery. 7. Start the vehicle with the BAD battery and then remove the jumper cables from the batteries in the exact opposite order you installed them.

How to charge a car battery while battery is in the car


No, do not disconnect your car's cables. Connect positive cable to positive one on charger cables, & negative to negative. Attach to DEAD battery FIRST. Then attach to car that's giving you a charge. BOTH CARS MUST BE OFF DURING ATTACHING PHASE. Then the car giving you a charge must start theirs. Let both sit like this for a few minutes (usually 3-5 minutes is plenty). Then try starting your car. If not charged enough, turn yours all the way off & continue charging for longer period of time. YOU DO NOT REMOVE THE CAR's OWN CABLES AT ANY TIME DURING OR AFTER THIS PROCESS, BUT ONLY WHEN A NEW BATTERY IS BEING PLACED IN YOUR CAR.

How do I give a jump start to another veichle?


Your jumper cables are most likely red and black. Locate the positive and negative terminals on your battery, they are marked ( + ) or pos.,that's the red one, and ( - ) or neg. that's the black one. Conect one end of your cables to your battery (doesn't matter which one you do first) make sure you are connecting the other end to the same terminal on the dead battery (that is to say positive to possitive) now do the same with the other cable. There may be a little bit of a spark that's normal when you make the final connection. The danger is in taking them off, do it in the same order that you put them on, if you take both cables off at the dead battery and they touch you are going to be having a bad hair day. the thing that most people don't get is you have to have a good clean convention. If you don't try wiggling the clamp on both batteries to make them dig into the terminals. Also there is a huge difference between someone who left the lights on in parking lot and someone with a dead battery on the side of the interstate. The guy in the parking lot has a dead battery, the guy on the side of the road has a dead battery and a dead alternator, he needs a tow truck, not a jump.

1966 mustang electrical problem


well Im not positive on that old of a car but I know for sure that newer cars are that way.If it was me before I would go splicing anything I would find some wire of the same gauge and make a jumper to see if it solves the problem then go from there.
