I have a Garmin GPS 89, I would sell, don't use it much anymore.

sam,
isnt the lowrance 2000 the one with the biggest screen? a friend mounted
one this year in a vfr plane and it is very easy to work and easy to see. it
may not be state of the art but has a lot more than i need. its screen is so
BIG! at $700 or so it will be my choice in a year when my project is done.

I think your right, but Garmin has some new products worth looking into!

Subject: | Battery Cranking Power |
--> AeroElectric-List message posted by: "DAVID REEL" <dreel@cox.net>
I took some measurements today because my Panasonic LCRD1217P battery cranking
power seems marginal on cold, 45 degree, days with my O360A1A and SkyTek permanent
magnet starter. I saw 5.5 to 6.5v from the starter side of the starter relay
to a stud on the vaccum pad of the engine accessory case. I also saw 5.5
to 6.5 v from the battery + terminal to airframe ground. The battery was fully
charged and measured 12.8v and was new. Assuming the battery - terminal to
airframe ground connection is good, it's new, and that about 200a is being drawn
by the starter, this gives a 25 milliohm internal battery resistance to explain
the 6 volt drop on starting. The specs claim the battery has 12 milliohm
resistance at 77 degrees. Would the 30 degree temperature drop be enough to
reasonably explain this big increase in internal resistance? Could the starter
be taking 400a? When the starter would stall, the battery voltage dropped
to about 4.5v.

If you want to see if your battery is holding up under cranking current,
you need to measure the voltage on the battery terminals. If you are
looking for losses, you need to measure the voltage on the starter
itself. You need BOTH measurements to figure voltage drop.
There are inexpensive meters that you just hold against the hot lead
from battery to starter that will show starter current draw. You should
be able to get one at a well-stocked auto parts store.
With those three measurements in hand you can get a really good feel for
now your battery and starting system are performing.
