Battery drained after a few hours and cannot satrt

Sometimes my Merc S320L cannot start after parking for a few hours. It happens about once a week, and I have to use another battery to jump start. I believe some electrical stuffs are still drawing current while the car is parked. Any advice how to determine which device is drawing current, and why? Pls provice some guidance on how to approach this type of problem.

This sounds like as if the battery is faulty. You will need to repllace your battery as your current battery is not holding its charge. Another scenario could be that your altenator is faulty, need replaced. Check for the light on your dashboard if it shows the light for the battery then it is your altenator.


Hope this helps.

My thought is the neutral safety switch is failing., or the gear selector linkage is out of adjustment-im not familiar with pt cruiser drivetrains, but the neutral safety switch allows a vehicle to start in only park, or neutral. Switch is located somewhere on the trans housing. Loose gear selector linkage can also be the culprit. My advice is to purchase a haynes, or chiltons repair manual specific to your cruiser's model year and follow the troubleshooting sequence for each. this will save you a lot of cash-

Just wanted to let you know to check the vanity mirror lights on the back of the visor. Sometimes they stay on and when they are on with the mirror closed, its hard to tell. Also, the regulator in the altenator could be going out. When it starts to go it does exactally what you described. Its either working or not so it can be tricky to diagnose. when you got your altenator tested it was probally working but stopped soon after and then started working again. Eventually it will go out and not work again if that is whats happening. Hope this helps.

Running so few miles has accelerated the aging of the battery - the battery never had a chance to fully recharge in such small trips -  so now you have to replace it a year sooner than usual.
Just replace it.

You have a direct current drain while the car is parked....a short or stuck relay or something is not shutting down when you turn the car off. This is called a key off parasitic electrical drain.You can test for this with an amp meter.
If everything is normal, you will read less than 35 milliamps, or .035 amps.(one hour after car is turned off) If the current drain is higher than that, you need to find out what is draining your batteries: You can start by pulling fuses until the load goes away. If that doesn't reduce the draw, you need to look for a wire that is corroded or frayed.
Good luck and happy hunting...
