1999 Volvo S80 will not hold a charge

My 1999 Volvo S80 will not hold a charge. I have replaced the battery, replaced the alternator, checked the fuses under the hood. I also replaced the starter. It will crank right up then as I'm driving down the street it will die out and the battery will need to be recharged. Please Help!!!

Tricky ... Was the alternator replaced with a 2nd hand one or a new one?

A defective alternator can allow the battery to discharge within a few minutes (the diodes in the rear of the alternator can burn out and cause the problem. The diode pack can be replaced). When this happens recharging the battery only replaces the power in the battery - which drains straight back to earth via the alternator, flattening the battery again - often within a couple of minutes or less.

Does the battery lose its charge when the car is standing or just when the engine is fired up?
If the battery loses its charge overnight, try disconnecting the wiring from the rear of the alternator (also look at the electrical connector that fits into the back of the alternator - look for melting/burning marks which suggest something may be amiss inside the alternator).

Let the car stand overnight with the alternator wires disconnected. Will it start up ok and drive (with the alternator wires still disconnected) the next morning?

You could also try just disconnecting the alternator wires, firing up the car and then driving it -
If the car drives ok without dying out and gets further down the street than it usually does, then it probably is the alternator at fault. The car should drive until the battery drains and has insufficient power to trigger the ignition. You certainly would get further down the street with a charged battery and disconnected alternator than you currently do.

It does sound as though you've had an alternator fault to begin with. If it has been replaced with a 2nd hand unit that unit may also be faulty. Rather than replace parts in desperation, visit an auto electrician's - within a few minutes they will be able to test the battery/alternator output and also identify where the lost current is going. It will be cheaper in the long run to have an auto electrician look at the charging system. It only takes a few minutes.

2000 S80 volvo nothing will work but the radio


check the 100amp main fuse located in the engine compartment fuse box the list of fuses will be on the cover but is easy to spot as is a large size fuse , there are sometimes another fuse directly attached to the positive battery terminal , if these are ok i'd have the battery condition checked as may be so low it will need replaceing , if you do have to replace the battery it is good practice to have the alternator charge rate checked at the same time as could be the reason for the faulty battery good luck

I ran out of gas in my 99 s80....after trying to start it 4 or 5 times now it wont turn over at all....I have replaced the battery AND the starter! Unfortunately five hundred some odd dollars later my s80...


So it wont crank or it wont start?

If it wont crank:
Check and see that all of your fuses are still good. Be sure to also check the fuse box under the hood.

If it wont start:
There is a test port on the fuel rail. Turn the key to the on position and then push the button inside the test port (like a tire valve) and see if fuel comes out.

If there is no fuel in the fuel rail, then you have an issue with your fuel pump/filter ect. This is very common after running out of gas.

Neither turn signals work on 1999 volvo s80


I had a similar problem on my S80 1999 2.9 . It turned out to be the SMS multifunction module in the steering column that had gone bad. I eventually had to have it replaced plus a software reload. It was expensive. Suggestions that did not work were to disconnect the battery, charge the battery, reload software . It was only after the unit was changed that the software was loaded at a cost

New battery and alternator. Battery still won't hold charge


Check all your fuses if you had a system failure it could have blown a fuse. I am not sure on your vehicle where the fuse is in the car or under the hood it could also have a relay. You can check your alternator by checking the voltage at the back of the alternator where the big wire bolts on. You should have 14+ volts at the alternator.

Cannot unlock trunk


Why don't you charge the battery under the hood so you can pop your trunk. You can't do anything with a dead battery.
