13.86 volts when the car is running means your alternator is doing its job. You can recharge the battery using a charger, this is more effective than having it charged by your alternator with the engine running. Once it has a good full charge (reading at around 12.6-12.8 volts) you can do a load test to see if it is bad. Most auto parts stores or places that ...

I just a hunch but check to see if there is anything stuck in the linkage under the hood that goes to the transmission shifter leaver I once had a little stone in there and once removed it was fine.

1- Installing a kill switch in the car is an alternative. A 300Amp Relay would do nicely. 2- Installing a separate 12V rechargeable battery to the ECU and other components would keep them going when the main battery is disconnected. Make sure to have an adequate diode on the power side of each desired component so that the power from the extra batteries ...

Same vehicle same symptom, it was the GPS, we just disconnected it and the problem was solved. Very annoying, took a lot of trial and error to find it.

Now when the engine is running, I get about 13 V of voltage: last time I checked, the tension was constant at 13,07 V (with no electric loads on), both at idle and at higher rpms. I have no mechanical experience, but looking up on the internet I found that a voltage around 14 V should be expected. Is it possible that the alternator they replaced is faulty? ...

Not cranking is not related to a faulty fuel pump. A faulty fuel pump may cause the engine not to start, but it won't stop the engine from cranking. To answer your question: A fuel pump van seize/stop working for many reasons including: Rust Old age / wear Blown fuse Bad / no electical connection When you turn the key to the run position (or if you have a ...

You can't revive the battery, especially if it was charged when cold its dead for sure. Just recycle it correctly. If you want to get new bike or replace your battery it's up to you. Just keep in mind this battery is dead and can even explode if you try to revive it via some fishy method.

You should never store or especially service a battery in the home or car. The acids do create toxic gasses and explosions are even possible.

You will need an actual battery charger. Most battery maintainers will not charge a completely discharged battery.

Yes, the smartphone takes power from the socket when it is powered. However if you check the demand of the smartphone in W and AH then you will find it is very small compared to the car battery capacity and the alternator output. Check the units: car battery in AH and smartphone mAH... If you have a car battery going flat it is due to one, or both, of two ...

No, it shouldn't. During a remap, there are tables which the ECU reads to know what/when/how fueling and other events should occur. This is in non-volatile memory. There are other parts of the ECU which will be wiped out, such as error codes and the fine adjustments the vehicle does to itself to get the tune "just right", which is in volatile ...

Your car has an electric fan at the radiator and the fan didn't engage when it had to. Or it didn't engage its higher speed when it had to. The result: your engine mildly overheated. What you have to check: Why the fan didn't start? Loose wirings, burnt fuse, dead relay(s), whatever? Signs of oil or coolant leaks. Signs of oil in the coolant or coolant in ...

What happened exactly? Was it that keeping it on 4000 rpm for 5 minutes caused overheating and this had nothing to do with the connected battery, or did battery have something to do with it? You were holding the engine at (relatively) high RPM for a sustained period of time with essentially no air flow over the radiator. That being the case it was going to ...

Typically, a battery with a dead cell, when fully charged will show the 12.5+vdc as you'd expect. However, once you put it under any type of heavy load (ie: trying to start the vehicle), the voltage will drop down to ~10.5vdc. There is usually a small amount of charge in the cell at first, but is soon wiped out after the battery is put to the test.
