Answers to frequently asked
can I hook up solar panels?
want to use solar panels to be able to run their accessories for as long as
possible with the engine off. You can connect the solar charge controller
directly to our power and ground bus bars. The solar charge will go into your
aux battery first to replace the power used by your accessories. As long as the
panel is big enough to keep up with the demand and charge up the battery, then
our smart isolator will link them together, and the solar will flow over to the
cranking battery as well.
I connect a trickle charger to keep both batteries charged?
connect a charger to your factory positive wire on the cranking battery and the
factory negative wire on the aux battery. This way the trickle charger works
just like your alternator - it will charge the cranking battery first for a
couple minutes, then the smart isolator links the batteries together to charge
the aux battery as well.

red light on top of my isolator stays on all the time. Is something wrong?
The red LED
light is a status indicator. On means the batteries are fully charged and they
are connected together. Off means they are below 12.7v and the isolator has
separated the batteries to protect your cranking battery from being drained by
your aftermarket accessories.

gets warm / hot / very hot. Is something wrong?
perfectly normal for your isolator to get hot. It can get up to 140 degrees,
even with the engine turned off, which is way too hot to touch with your hand,
but not nearly hot enough to hurt anything around it. This is a normal
characteristic of any electromechanical solenoid device.

my headlights/radio/dome lights turned on, and now the engine won't crank. I
thought the system would turn off the cranking battery to protect it from
getting too low.
positive wire harness feeds power directly to your fuse box, which means all of
the factory circuits are powered from your cranking battery. The isolator does
not turn off power to the fuse box. It 'isolates' the 2 batteries from each other,
to protect your cranking battery from being drained by your aftermarket
accessories that you have wired up to the bus bars. If you accidentally drain
your cranking battery, that's when you'd use the boost button to jump start
yourself from the second battery.
factory post clamps won't get tight enough on the battery post. It is loose and
causing weird electrical issues.
battery post clamps are made of light duty stamped sheetmetal, and are easy to
damage. First, make sure the post clamp is fully seated all the way to the
bottom of the battery post. Try loosing up the post clamp nut so it is very
loose, then use a large socket and gently tap the clamp down onto the post. Now
tighten the clamp nut and see if it is secure. You can also try using a battery
post shim, available from your local auto parts store, to fill the gap between
the clamp and the post, allowing the clamp to tighten down more securely.
need an sPOD, or is it unnecessary since the kit has the power and ground bus bars
for hooking up my accessories?
system from www.4x4spod.com is a great compliment to our dual battery system.
It allows you to easy add electrical accessories that need a fuse, relay, and a
switch. It does have limitations, however, with the amount of current that can
be used through any one switch. For example, you can't control a winch with it
due to the very high amp draw for the winch. Our bus bars are perfect for
connecting accessories that need direct battery power, or for those that come with
a wire harness that includes a fuse, relay, and switch.
I connect an sPOD system to the dual battery kit?
source unit should be connected directly to our power and ground bus bars. For
the best connection, we recommend using a larger ring terminal on the positive
lead so that it can be connected to the large center stud on the power bus bar.
The sPOD's negative lead should fit the center stud on the negative bus bar.
sPOD is turning off my accessories. Did I hook it up incorrectly?
The sPOD has
a low voltage monitor that will automatically shut circuits down to avoid
draining your battery too much. When adding an sPOD to our dual battery kit, we
recommend you pull out the 2 amp fuse inside the Source box. It is the only 2
amp fuse you'll see when you remove the cover. This will disable its low
voltage cutoff system. Since you have 2 batteries, and since our smart isolator
will already protect your cranking battery from getting drained, you probably
don't care if your accessory battery gets drained down all the way. That's why
you have 2 batteries in the first place!
ok to use my favorite brand of batteries, or are the Optima and Odyssey
batteries the only choice?
Any Group 34
battery will work in our tray. That refers to the physical size of the battery.
We offer Odyssey batteries through our website as a convenience for people who
want to have everything delivered to their doorstep, rather than having to go
to the store to buy them and pay sales tax, and have to carry 2 heavy batteries
home to be installed.
ship to international customers?
International shipping is no problem.
