Question about 1999 Volvo V70

Volvo V70 electrical problem

Hello, my battery died while driving, the car stopped. I checked the voltage, it is only 11.0 - 11.5 volts even with the engine running. Belt is OK, I guess it is either the alternator or the voltage regulator. Fuses seem to be OK. Is there anything I should check before I take it to the shop? I mean any hidden fuses, relays, switches, connections, anything??? Ho can I tell if it is the voltage regulator or the alternator itself?

Thanks :)

    Thanks for your help!

    I noticed when that light is on, my voltage is reading 10 or 11volts. When goes out reading returns to normal 12v. Alternator, ignition switch and OD relay have been replaced. What about the instrument cluster ckt bd or a wire that's grounded?

Had the same problem with an s80 this week- no warning lights nothing. was the regulator. when you have it fixed cancel all the trouble codes as when voltage is low everything registrs low signal input and makes the car go into get me home mode.

My 2002 volvo s60 shut off while i was driving and now all it does is click like my batterie is dead..i bought a new batterie and even tryed to jummp it , but only a click


Could be a bad battery cable or connection ! If it clicks it must be getting some voltage . A voltage drop test of the starting circuit would be the thing to do . Starter Voltage Drop buy yourself a volt meter . How to voltage drop test starter motor circuit . Find wiring diagrams for your vehicle , not all car makers do it the same way . http://www.bbbind.com/free_tsb.html free wiring diagrams . Watch videos on basic automotive electrical testing , how to read a wiring diagram . Then test the electrical circuit of the starter system .

96 cadillac eldorado etc battery not staying charged when the car is started the battery goes up to 14 when driving and press brake voltage drops 11-12(car may even die) and to 13+ if u give it gas


Does the vehicle start after sitting over night or do you need to jump start it . Is the charge light on ( batt. symbol ) at any time ? Serpentine belt good , tensioner good ? Battery cable connections good an tight and no corrosion ? Battery also good ? That is normal for battery voltage to jump up to 14 volts after starting , alternator is replenishing the battery after starting ,that draws down the battery . Going down to 11 or 12 volts when stopping and almost stalling isn't a charging system problem . You have a idle problem , IAC - idle air control valve or dirty air passage , a vacuum leak . Giving it gas and it going up to 13+ the alternator is working . Your best bet take it to a qualified repair shop and have it check .

Driver side low beam headlamp out. replaced bulb--no go. checked fuse-fuse ok.


Remove the new lamp

Put a volt meter black lead to the engine
for a good ground or battery grd post

Then turn on the light & probe the lamp socket
one or two wires should read battery volts &
most likely the balck wire is ground & won't drop
any voltage

If good there or compared to other light connector
go after a broken or open ground wire

Car won't start. Battery power seems fine. Turn the key, no cranking, lights and radio die with key in "start" position.


Hello davidoz,

Your description sounds like a bad battery. Do you have a volt meter to watch the voltage as you turn the key to start? The voltage on a good battery( meaning fully charged) should stay about 11 volts while cranking, if it drops below that suspect a bad battery.

Another possibility is that the battery is good but the alternator is not charging.

Will it start with a jump? If is does check with a volt meter the out put of the alternator it should be 13.8 volts or slightly higher.

netvan

Where exactly is the front O2 sensor on a 1999 S70?


For 1998 Volvo V70 2.4L MFI DOHC 5cyl the Oxygen Sensor is located under vehicle, center, below front seating area, mounted in top of exhaust pipe.

The oxygen sensor produces a voltage within 0 and 1 volt. When there is a large amount of oxygen present (lean mixture), the sensor produces a low voltage (less than 0.4v). When there is a lesser amount present (rich mixture) it produces a higher voltage (0.6-1.0v).The stoichiometric or correct fuel to air ratio will read between 0.4 and 0.6v. By monitoring the oxygen content and converting it to electrical voltage, the sensor acts as a rich-lean switch. The voltage is transmitted to the engine controller. The controller signals the power module to trigger the fuel injector.

Low voltage warning light comes on and car died. Replaced battery and now the sunroof will not close even though car starts. Warning light about electrical problem is still lit.


More than likely you have to bring it to the dealer to have your control module reset. When the battery dies unexpected some of the control modules will go in to what they call "sleep" mode. Sometimes you can take the negative battery cable and put it on the positive for about 10 min. It might wake the system back up. This does not work all the time but its worth a try before you bring it to the dealer.

Issue with dash lights dimming while driving,


If the battery and alternator tested fine. I would have the charging system rechecked when engine is hot and at high rpm's. This way the checks are being done as if you were driving and driving for a long time. Alternators can work fine when cold but weaken when hot or stop working. This problem is not rare but only is seen occassionly. Unless it was checked at an electrical shop the average shop doesn't run these tests for they don't see the problem often enough to automaticly run them at all times. Good luck and let me know how you make out.
