The most common reason a car battery is draining is a parasitic drain caused by a faulty electric consumer, like a bad door lock switch or a trunk lock switch. It …
How to easily diagnose common automotive electrical problems
The starter manufacturer had the wrong solenoid resistance and it just drew too much current! I could have switched starter brands (the best idea), or do what I did: let the starter circuit (low current) operate a relay with a bigger fuse and wire (higher current) coming directly from the battery. Been starting well for many years.
Most newer vehicles have a battery management sensor that monitors the current state of the battery and the electric charge that is coming from the alternator. If the voltage is too high, the alternator may be disengaged so it no longer produces a charge, or the battery circuit may be isolated to protect the battery from damage.
When the starter is turned on, the 12 Volt (V) car battery sends current to the starter motor. At this instant the resistance (R) of the motor is just the resistance of the copper wire that makes up the stator and rotor coils and is therefore low (less than 0.05 Ohms). The initial starting current (I) is therefor high (greater than 240 Amps ...
The crimp terminals and battery poles are under too much stress and will come loose over time. A good example of this is the wiring between batteries to form a large battery bank. ... When the wire in the fuse has melted, the electrical circuit has been broken and no more current will flow in the circuit. Once the fuse has blown" it will need ...
hey guys im having a weird problem that I personally have never seen before.With my car running at idle, I used to have my 4 channel and my sub amp (just on, no load) with maybe .1 or .2 voltage drop.All of a sudden the other day my sub amp would draw me down to the low 10''s with no music playing...
If the ammeter reading exceeds 23 mA, something may be using too much power. If excessive parasitic draw is present it will need to be corrected so the battery does not drain. To determine the source of Parasitic Draw (Dark …

Finally, the display''s refresh rate matters a lot.The refresh rate represents the number of times a screen refreshes every second and is measured in hertz (Hz). Newer phones have 90Hz and 120Hz ...
7 Symptoms of a Bad Ground Strap (and Replacement Cost)
By putting way too much current through the circuit, the wire in the taillight would get very hot and melt. This could very easily start a fire, but it sounds like you got lucky. ... broken, or corroded. If your battery actually died within 3 days, I suspect there is a parasitic draw. You should be able to locate it using a multimeter if this ...

What happens to a fully charged battery, when you continue to …
Once the battery is fully charged it will not accept any more energy (current) from the charger, since all the energy levels that were depleted when empty are now at their …
If the ammeter reading exceeds 23 mA, something may be using too much power. If excessive parasitic draw is present it will need to be corrected so the battery does not drain. To determine the source of Parasitic Draw …
8. Old Car Battery. Sometimes, the battery simply becomes too weak and old to hold a charge. In normal conditions, the car battery can last between three and five years. However, if you drive in extreme temperatures or push your vehicle to its limits, you might go through batteries more often. Diagnose Drained Car Battery
Here''s the Truth Behind the Biggest (and Dumbest) Battery Myths
And if too much current is delivered to a battery, that could mean ripping out too many of those lithium ions and leading to the same kind of degradation …
What Happens If the Battery Current Sensor is Bad?
Battery Current Sensor Bypass . A battery current sensor is a device that measures the current flowing in and out of a battery. It is typically used to monitor the charge/discharge current of a lead-acid battery, but can also be used with other types of batteries.The sensor consists of two parts: a sensing resistor and an amplifier.
Electric cars: What will happen to all the dead batteries?
