Nope,
never replaced the battery, but it was replaced by VM about 1 year after
installed (sent back to them for some repair work, including the Leaning mode
fix, which they never did get fixed).
Do
you know if the details on this battery replacement are on the LML? If
so, I’ll check, otherwise do you know where/how? User
servicecable? Size?
Thanks,
Matt

problem
There
is an internal battery in the VM1000 that needs to be replaced periodically.
VM says about every 7 years or so, I think. Have you ever replaced this
battery? If not, this would be the obvious first step.

problem
My
VM1000 has always been a bit of problem, but now the problems have increased
and I need to resolve them. Any thoughts on any of these issues?
I’ve been flying the 360 since 2001 and I put the date the problem started
in parentheses):
1.
Leaning
mode (never worked since day one). Pushing the button to go into the
leaning mode has never functioned. Just doesn’t do anything.
2.
Amps
(February 2010). I’ve noticed the amp-meter bouncing around. It
used to be fairly steady in the 18-20 amps range, but now it is more like 16
for a while, then bounces to 26 or something. It’s not related to
landing lights, radio com, fuel transfer pumps, or any evident change in
load. The alternator (B&C) is about 6 years old and the belt is,
according to the A&P, okay but could stand to be a bit tighter.
Voltage regulator is B&C too.
3.
AutoTrack
(March 2010). Just stopped working. Pushing the button for
AutoTrack now does nothing.
4.
Fuel
Remaining (May 2010). Unable to add fuel to the tank. I can cycle to
the “add fuel” point and then push buttons to add 10 gal units or 1 gal
units – both register as “to be added”. But then when I push the
button to cycle out of the “Add” mode it doesn’t register the “add”.
So it always indicates zero fuel now and I can’t add any!!! I’ve tried
all sorts of amounts but nothing will work. It’s been like this for 4
flights now… this is the straw that broke the camels back. I need to
get this fixed now. NOTE: I do still have a header tank gauge
and separate totalizers on each wing. I am NOT flying without knowing
my fuel quantity… this is just another check.
Any
help would be appreciated, including tips on how to get in touch with
VM…
Thanks,
Matt
