&gt;&gt;&gt; My dealership is claiming that there is a brand new memo that came
&gt;&gt;&gt; out stating that remote starters kill the battery for in 2006-2007
&gt;&gt;&gt; Explorers. Is there anywhere I can find this information on Ford's
&gt;&gt;&gt; website? Is there a national service hotline? The vehicle ('07
&gt;&gt;&gt; Eddie Bauer) was in two weeks ago for a new battery and at that
&gt;&gt;&gt; point they said it had nothing to do with the remote start, now
&gt;&gt;&gt; the battery is dead again and they are stating there is a new
&gt;&gt;&gt; memo. Thanks.
&gt;&gt;
&gt;&gt; Is it an aftermarket remote starter or a Ford installed remote
&gt;&gt; starter?
&gt;&gt;
&gt;&gt; The remote starter definitely pulls some power all the time, but I
&gt;&gt; can't imagine it is enough to kill the battery unless there is some
&gt;&gt; sort of problem where it repeatedly tries to start the vehicle and
&gt;&gt; can't.
&gt;&gt;
&gt;&gt; I don't see a Technical Service Bulletin that address remote
&gt;&gt; starters directly, but there could be an Oasis message on the
&gt;&gt; subject. I can't see those.
&gt;&gt;

&gt;
&gt; Thanks Ed, it is after-market. The dealer told me I couldn't get an
&gt; OEM starter for pre-2008 Explorers. The thing is that it isn't
&gt; drawing on the battery, if that was the case I'd just jump it, they
&gt; are saying it is causing an internal failure in one of the cells.

You should ask them to let you see the memo. What is the proposed
course of action? Remove the remote starter? Ford definitely sells an
accessory remote starter for pre-2008 Explorers (Ford P/N
2W7Z-19G364-BA). They recommend dealer installation. What brand of
remote starter do you have?

The only thing I have seen that might be related to your problem is
about the remote starter keeping the GEM alive, and this kills the
battery. Does your remote starter include a remote entry function
(lock/unlock the doors). It seems that some remote starters that tie
into the factory door lock wiring need to be isolated from the factory
wiring with diodes, otherwise they will draw enough current from the
system to keep the GEM alive, resulting in an increased power draw,
which kills the battery faster. Repeatedly drawing the battery down to
a low level can damage the battery, leading to a total failure. Modern
starters will turn over at relatively low voltage, resulting in a much
higher current draw, which can damage the battery. You should measure
the current draw with everything supposedly &quot;off.&quot; You should also
check the battery after the vehicle has been &quot;off&quot; for an extended
period. I'll be the voltage will be low (less than 12V).

The smartest &quot;Ford&quot; guy on Usenet is probably Jim Warman. If anyone
likely to see this post know about a &quot;memo&quot; it will probably be Jim.

The only Service Bulletin that would seem to apply is TSB 07-5-13:

FORD:2005-2008 Mustang
2005 Explorer Sport Trac
2005-2008 Expedition, Explorer
2007-2008 Explorer Sport Trac
LINCOLN:2005-2008 Navigator
MERCURY:2005-2008 Mountaineer

ISSUE:

Some 2005-2008 Mustang , Explorer 4dr, Mountaineer, Expedition, Navigator,
2005 Explorer Sport Trac and 2007-2008 Explorer Sport Trac vehicles may
experience a no start and have a discharged battery. They are usually stored
for prolonged periods of time or are driven infrequently for short
distances. Batteries will discharge while the vehicle is in storage due to
normal current draw loads. Over a period of time, 30 days or more, vehicles
in storage will have shallow to deeply discharged batteries as a result of
lack of use or normal current draw.

ACTION:

Follow the Service Tips steps to correct the condition.

SERVICE TIPS
Charging system diagnostics and battery draw test are located in Workshop
Manual, Section 414-00.
Discharged batteries need to be properly recharged following the procedures
in TSB 07-5-8.

All modern automobiles have several micro processors in their electrical
system that will draw small amounts of electrical current when the vehicle
key is off. Normal current draw is between 20-30 milliamps (workshop manual
specification is up to 50 milliamps 0.050 amps).

The more discharged a battery becomes, the more susceptible it is to
permanent damage. This is more likely in low temperatures (below 32 °F (0
°C).

Batteries will discharge while the vehicle is in storage due to normal
current draw loads. Over a period of time (30 days or more), vehicles in
storage will have shallow to deeply discharged batteries as a result of lack
of use or normal current draw.

NOTE:ELECTRICAL OR ELECTRONIC ACCESSORIES OR COMPONENTS ADDED TO THE VEHICLE
BY THE DEALER OR BY THE OWNER WILL INCREASE THE CURRENT DRAW LOADS AND
ADVERSELY AFFECT BATTERY PERFORMANCE AND DURABILITY.

The vehicle's charging system is designed to supply the vehicle's electrical
power needs and maintain the battery to near full charge during normal
vehicle use. The charging system is not capable of bringing a deeply
discharged battery back to near full charge in a short amount of time such
as allowing the vehicle to idle for 15 minutes to &quot;recharge the battery&quot; or
from short drive cycles.

Short drive cycles will only provide a small surface charge to the battery.
To fully recharge a battery that is fully discharged requires operating the
vehicle for approximately two (2) hours with engine speed above 1500 RPM.

Vehicles that are stored for extended periods or are driven infrequently for
short distances may need to use an auxiliary battery maintainer/charger that
is expressly designed to maintain the battery state of charge during
storage. These maintainers/chargers are available in the automotive
aftermarket and should be used according to their manufacturer's direction.

The dealer printed something off that looked similar to that but different
enough that I'll try to post it tomorrow. Also, this vehicle was never
parked longer than 10-12 hours.
