[DeTomaso] NPC - jump starting a car

Sun Sep 1 09:08:54 EDT 2013

On a related note, two points of data of limited utility that I have learned
since yesterday:

1) Leaving your car radio with the display on will drain the battery in 7
days. Possible less, but if you try to start your car on the 7th day you'll
just get a click
2) A Ctek battery tender will charge a (good but drained) battery in under
24 hours. 

I took the battery out of the Pantera last weekend to start my wife's car
when I was unsuccessful jump starting it. It put it back in last weekend,
and apparently when you hook the battery up, the radio display turns itself
on. I imagine it doesn't use a WHOLE lot of juice, but a week of text
scrolling across the screen and the backlighting on "full" will do the
trick. I had a car cover on and had only uncovered the front trunk, so I
didn't notice the glow coming from within. 

I don't disconnect my battery, but keep a Ctek battery tender connected at
all times. I could disconnect the battery, but it is a real pain to re-set
the factory digital clock thing...

I suggest you disconnect the battery if you're not going to use the car 
in a long time.

My son parked his golf GTI in our garage about two years ago when he was 
getting it painted. The battery would drain in about two weekss, likely 
due to the stereo and alarm sucking it dry.

I disconnected the battery and charged it fully, and then it would hold 
the charge for months. I used to top it up using one of my CTEK:s about 
every four months or so.

For the P-car I have a CTEK with a long cable and a lighter plug, and I 
plug it into the lighter socket every time I park it in the garage.
