REFLECTOR: battery

[Alex Balic]

I have a couple of Hawker Odyssey batteries- I think 925 is the number on
them _ I  have 2 because I am all electric- including engine computer, so I
want the extra capacity, adn redundancy,  but either of them alone will
crank the hell out of my engine- my neighbor has an RV6 with the smaller
Odyssey (600 series??) and it really cranks his I0-360 SkyTek -spins it
fast- not the usual chugging/hoping that it will start before you run out of
juce sort of start  - you can find them on-line reasonable- I got mine from
some motorcycle shop on e-bay for less than 300 for the pair as I remember.
they are small, and can be mounted in any orientation.

I have the same set up (including SkyTec Starter 149-12LS) except my ground
is a 1/2" id copper tube (also serves as the vacuum line).  It always cranks
easily.  
 
I suggest you check for voltage across battery hot post to the starter while
it is cranking.  Also, check for voltage from the ground post on the battery
to the engine crank case.  In both cases, there should be no voltage while
cranking.  If there is voltage, then check between each connection on the 12
volt or ground wires.

The battery is an Interstate, 12 volt, mounted in the nose, with #2 stranded
wire running all of the way back to the engine. Connections are clean. As
long as I have owned this aircraft, starting has been a bit slow. When you
first apply power to the started it will hesitate, groan, and then begin to
turn the flywheel. Sometimes I will have to let off on the key and try again
to get it to turn over. Once that happens the engine will usually start on
the first revolution, providing I don't flood it. I have a sky-tec starter,
model #149-12LS. I have a battery tender plugged in at all times when the
aircraft is in the hanger. Hope this is enough information.

Lou,

 

Which battery are you using now?  Is the battery in the nose position (under
the canard)?  Are the battery cables #2 copper with solid, tight end
connections?  Has starting always been weak, or has it gotten weaker
recently?

 

Starting problems may be due to the battery (particularly if it's old or
abused), but there are lots of other potential causes.  Generally any sealed
lead-acid (SLA) battery of moderate size will have plenty of snort to crank
an engine, provided it is getting charged.  A bit more information is needed
to help with diagnosis.

Hi guys

I am not happy with the cranking power of my battery. I am turning an LYC
io-360, any recommendations?
