The answer is, yes, it can. If you try to start your car with a faulty starter, you could drain the battery even faster. A faulty starter is one of the most common causes of car fires. If the car starts and runs, but you can’t start the engine, the starter may be faulty. If it doesn’t run, you may need to replace it.
You can also check to see if the ignition switch is in the “on” or “off” position with the key in your pocket or on your key ring. The key should not be in any position other than “ON” when you first turn it on, and it should stay in that position for at least 10 seconds before turning it off.

Can a starter relay drain your battery?
Your engine is turned on by the starter motor. A starting relay completes the circuit before reaching the starter motor, but also increases battery current when it passes through it. A defective starter relay will prevent your battery from delivering electrical power to the engine until the relay is repaired or replaced. If your starter fails, you will need to replace it with a new one.
What can drain a car battery when it’s off?
Interior lights, door lights, or even bad relays can drain a car battery when it’s off. You don’t have to worry about the battery dying while you’re playing music because the engine runs and the alternator replenishes the battery. But when the engine is running and the car is on the road, things can get a little more complicated.
If you have a battery-powered car, you’ll want to make sure that your battery is fully charged before you start driving. You can do this by plugging your car’s battery into a wall outlet, but you can also do it the old-fashioned way — by putting it in your trunk.
Can a starter solenoid drain the battery?
No, a bad solenoid can never drain your battery. A bad set of diodes in the alternator will cause the battery to go down. A “start-stop” problem can be caused by a faulty starter motor. If you have any of these problems, it’s time to get a new battery, or replace your old one.
How can I tell if my starter is draining my battery?
The starter will draw a charge from the battery. If it’s drawing too much, that’s a clear indicator that’s has failed. The engine of the vehicle will shut down if it continues to draw too much power. If the starter fails, the vehicle will not start, and you will have to start from scratch. You will need a new starter.
How do I know if my starter fuse is blown?
The probes of your multimeter should be placed on the ground lead and the ignition circuit terminal. If the multimeter reading is more than 5 ohms, you have a problem with the ignition coil. If the readings are less than 1 ohm, the coil is working properly.
How do I know if my alternator is draining my battery?
The engine isn’t running on its own because the alternator isn’t generating enough electricity. The problem may be in the wiring harness if the car continues to run. If you suspect a problem with the electrical system, contact your local dealer.
