Sounds like the alternater is a reasonable suspect to me. Second guess would be the Ghost of Chrysler Past!

AnswerFirst I would start a fresh, new post. Second, what motor and model do yuou have. I would check the ground or negative cable for a loose connection first. AnswerI was recently having similar problems. lights diming & brightning wipers slow alternator kept blowing up. finally transplanted the "brain"... got a new ECM did it my self fairly simple but not cheap. i believe you can get it tested. but i would sugest you do the work your self. i saved 1300.00 that way found the part @ the wreckers 4 cheap! but make sure there is a warenty of sorts. just in case. Answersounds like the alternator to me AnswerI HAD THAT TO HAPPEN TO ME ONE TIME ON A Pontiac IT TURNED OUT THE BATTERY WAS SHORTED INSIDE OF IT SO YOU MAY WANT TO HAVE THE BATTERY CHECKED AnswerGrounds, grounds, grounds. Check to be sure all grounds are clean and serviceable. AnswerIt could be about a thousand things. Bring your alternator in somewhere and get it checked. If it is bad change it. If it's good bring the battery in and have it load tested. If it is good, then start looking at grounds. If all your grounds are good and clean then start looking at reseting your ECM. Go into the dealership and start asking questions. Most mechanics are good guys they will try to help you out. It doesn't hurt to bring in a coffee for the guy before you ask. Good luck.

to move a battery voltage wildly take a lot of current which the car Even if running cannot supply. Basically the battery is not very well connected to the source or a depleted battery

There are many things that can cause this but first check to make sure that the system has freon, if not then you will have a leak (most common places are the evaporator and compressor).

Will vibrations from your sub help blow a fuse in your amp?

Blowing fuse versus vibrationNO, vibration would not be the cause.The cause for fuses to "blow" is the flow of electrical current in excess of the capability of the wire to carry.Fuses are designed, manufactured, and installed to protect the wire from over-current conditions which could cause the wire to melt its insulation an cause a fire.Some ignorant people will suggest installing a larger fuse, but that will not solve the problem, AND...Can cause serious damage to any electrical equipment on the circuit, and..In a "worst case" situation, cause a fire which can destroythe entire electrical system, and possibly your vehicle.
