View Full Version : charging system strangeness

2013.02.26, 15:20 PM
Every couple of weeks, I am unable to start the Volvo. It is a definite progression, starting with me cleaning the battery terminals and charging up the battery. Then, over several weeks, it struggles a little more every day to start. Not really a noticeable decline day-to-day, until there's just not enough power to turn the engine over.

Alternator is putting out 13.5 volts on the dot, battery is a not-even 2 year old Interstate, fluid level is fine. Each time that I put it on the charger I pull the terminals and give them a good brushing.

Have you checked to see if you have Parasitic Draw?

if it were going dead overnight I would be looking for something like that, but since it diminishes over weeks, and I'm driving (and thus charging) every day I would think other causes

I think Anthony is right about where to start. Check for a parasitic draw first.

maybe I can use this as a reason to buy a nice multimeter
