Porsche: Porsche Winter Battery Charge Question

The charger should only be able to put out 1 to 1.5 amps and therefore, the
charge current would not blow the fuse. I would then guess that you have
something wrong in the charger that is causing it to draw current from your
car and obviously more than 15 amps. I do not know how what causes a
lighter to eject but if I had to guess, I would think it was related to heat
in some
way. That may point to the problem in your charger being inside the adapter
that goes in to the lighter socket (short).

When this happens, is the plug on the end of your charger hot?

Have you tried this in any other cars?

How long after you plug it in before it is ejected from the lighter socket?

Do you have a DMM (Digital Multi Meter) or any type of DC Voltage measuring
device? If so, there are several things you could easily check.

Does the lighter work in the car (if not, you may have a problem in the
lighter socket).


I also have a Porsche Charger that I have a question about. I do not see
the red light
lit on mine. If I unplug it for a few hours and plug it back it, the red
light does come on.
I have read the directions and it said the red light is only on when it is
charging. How
often did you see your red light lit on your charger las year when it was
working?

Thanks!

I never liked the idea (or price) of that unit, bought a "Battery
Tender +" for less and it not only maintains perfectly it has a lot of
other benefits built in. Maybe Porsche will replace it?

Dan,

Thanks for the excellent post. Frankly I'm embarassed that I had not
thought about a rational approach to isolating the problem.

Having said that I checked the charger. After ten (10) minutes the
lamp turned off. Note: my recollection from last year is that the
lamp remained lit all winter. The lighter portion was not warm which
prompted the lighter test and that was also negative and the fuse is
still in good working condition.

Given these results it appears I have a wiring problem.

So once again thank you for the response. It was very helpful.

Paco,

I recall the red light being on every time I checked it last Winter, but I
have
not seen it on yet this Winter. Unfortunately I keep my Boxster in a
"Bubble", so
it takes a while to get in to it. I plan to see if I can take the charger
apart and measure
the voltage where the wires connect both with and w/o the charger plugged
in.
Of course, that will take some special driver I may not have to get it
apart. But
doing that I should be able to measure just the battery voltage and the
voltage with
the charged powered up.

Have you determined the problem with yours yet?

Dan,

Some additional follow-up. I just checked my charger. The battery is at
13.6 VDC without the charger being connected to the AC Outlet. When I
connect the charger to the AC, the voltage goes to 13.8 VDC and the red
light does not stay on. So I am assuming it is in a low "Maintain" level.
It is doing exactly what it is supposed to be doing.
