I have an '06 MC with 96,000miles. I replaced the battery in Januray of this year. Starting a month or so ago, it doesn't turn over as rapidly as it did when it was new. There is a slight hesitation.

I thought I had read a thread on here about some cars having a faulty pump (can't remember which one) still running once the car is off and draining batteries, but I cannot find it

 

You are referring to the power steering pump fan which, when faulty, will continue to run when the car is off. You will definitely know it's on. It's loud. This will eventually drain your battery though, not make it weak.

 

A couple of summers ago, during hot weather, the cooling fan on mine continued to run, and eventually did in the battery that needed replacement anyway after 7 years.

 

Thanks! That is what I remember reading. I don't hear anything when the car is off so that's not it.


razz, thank you. I don't hear anything when I turn the car off. So i guess as long as the car starts I won't worry about it

 

Clean your battery's terminals and the insides of the cable connectors with a wire terminal brush. Also clean the engine ground strap terminal and tighten the nut. (Be sure to remove any ring/s from your fingers before working near the battery). Once you've done these things, it may or may not improve the situation but at least you can eliminate this from the equation.

 

Good idea, I'll give hat a shot.
