 Posted: Mon Mar 05, 2007 12:10 pm Post subject: find small battery drain |
 |
|
I left my truck sit in the barn all winter. I went to start it four days ago
and found out that the battery had froze and busted. (Batteries only freeze
if discharged.)So, I put a new battery in. Last night, I found out the truck
needed a charger to start.
There must be something slowly draining power out of the battery. How do I
go about finding the problem?
BTW, I compared notes with my neighbor who had also just came back from a
winter down south. His septic tank and drain field froze up - guess my
little problem is not so bad.

Hi Karl,
the techo way is to use an ammeter. If you dont have one, disconnect
the black (neg) lead from the battery, connect a small 12v bulb
between the (neg) terminal of the battery and the now stray earth
(neg) lead. If there is external current drain, the bulb will light
up. Progressively pull fuses, one at a time, till it goes out. The
fuse that causes it to go out is the faulty circuit. Look in the
service manual, trace the wiring through, progressively disconnect
things until you find the fault.
The above assumes that
1.Your charging circuit is working (is there a ammeter on the
dashboard?)
2.The (new) battery you put in was fully charged and in good condition
3. The truck motor was run for a while to get a charge into the
battery....
4. My incredible talent for completely stuffing tech explanations,
even for things I am pretty good at, does... not strike again.
In return - can you tell me when apples are ready to pick to eat -
yeh, stupid question, obvious answer is to pick one and eat it - but
its a miniature tree, its first crop, it has five apples on it - don't
want to get a picking team in until I am sure they are ripe......

Thanks for the quick reply. Sounds like a plan - I'm off to the shop to
figure out how to clobber in a 12 volt light.

Actually, I tell everyone that's my biggest job. Every morning during
harvest, I walk the entire orchard and judge ripeness. Proper maturity had a
HUGE impact on fruit quality. I look first at estimated harvest date DAFB
(days after full bloom), then fruit background color - each variety has a
different spec. , then slice an apple at the equator to judge seed cavity
maturity;flesh color; starch content. FINALLY- I just take a bite. (I really
ham this whole explanation up for my school tours - the kids just love it
when I show them the real last test) Seriously though, you're evaluating
acidity, sugar level, starch level, and crispness with the taste test.
