Question about 2008 Toyota RAV4

3 Answers

I had a store repair shop install a new battery in my 2008 Rav4 V6 Limited. During the install, the alternator fuse blew and they apparently had a very difficult time accessing the fuse box and locating the correct fuse. When I picked up the vehicle, the 4WD yellow warning light was lit and stayed on through driving and several restarts. No other warning lights were on. The repair shop could not find an engine code and neither could Autozone. The vehicle ran fine before this and seemed to drive fine afterward. I plan on taking it to the dealership once the weekend is over. The owner's manual states to turn my engine off and let the drive train cool off, but my car was cool to begin with. What did they do to my car? Is it safe to drive with this light on?

    Thanks for your helpful comments. It turns out that mekanik84 was right. I spoke to the shop manager today and he admitted that the mechanic had indeed switched the terminals during the installation. I have a feeling that they blew more than one fuse because they worked on my car for over 6 hours and told me that they checked every fuse. I will pass on the suggestions by Marc99GT to their mechanic when I bring it back tomorrow. I'm hoping that the damage was limited to just fuses.

Unfortunately it sounds as tho someone back boosted your car, so terminals on the wrong spots. I would push the installer of the battery to repair your problem or at least agree to cover any costs. On some vehicles computers, modules and other components can be damaged by back boosting a car

Since they blew one fuse, it is possible they blew others as well. There is a 7.5A fuse that I believe powers the 4WD control module. It is in the instrument panel junction box cowl on the left. There is also a 10 amp fuse for the module ECU-IG1. It is located in the same box as the other fuse. I would check those 2. One other fuse I would check is the other 7.5A for the gauge related to the 4WD on the cluster, but I guess that is working since it appears on the cluster.

I hope that helps and good luck.

Briefly installed battery backwards. 2000 Ford Ranger. New Battery, new alternator, but alternator not charging battery. Truck starts on battery-new starter motor. Lights work, all electrical works

Is this the alternator that was in the vehicle when you hooked the battery up wrong? If so, you probably blew out the voltage regulator in the alternator.

Hqw do you replace the alternator on the 2008 hyundai veracruz

this is a very common issue with the 3.3 and 3.8 v6 hyundai engines. it is recomended that you reseal the valve cover with new silcone and a gasket during the repair of the alternator.
  1. Disconnect the battery negative terminal first, then the positive terminal.
  2. Disconnect the alternator connector (A), and remove the cable from alternator "B" terminal (B).
3. Remove the drive belt (C).
4. Pull out the through bolt and then remove the alternator (A).
5. Installation is the reverse of removal.

I have a mitsubishi 3000gt and my alternator fuse keeps blowing. i think it might have to do with my aftermarket alarm and automatic start, but i had just gotten a new battery, alternator, and egnition...

If they go out, you need to go back to that shop and have them repair it correctly. Apparently they had someone work on it that didn\'t know jack about installations. I imagine they didn\'t install a relay and hooked it up to the alternator directly and somehow grounded the alternator with something in the car. If your blowing alternator fuses, that is serious in most cases since the alternator puts out heavy amps. Be sure your using the proper amperage fuse for the installation as well. Try returning to shop that installed the stuff and don\'t let them get away with keeping your car that long. That is ridiculous and if your not happy with their attitudes, report them to the BBB.

Battery drain

Since you have replaced the battery, the next step is to make sure the alternator is charging the battery, and to look for a power drain.
When the car is off, someone would remove the battery cable and using a test light as a jumper pull all of the fuses and disconnect the main wiring until the light goes off. That circuit would be tested for a short or a component not turned off.
