transformation of Project Tahoe into our chase vehicle and off-road
play vehicle, we were in need of an electrical system upgrade. We
had already plugged in one set of lights and plan on a full set of
additional electrical accessories. We are even looking at
installing a receiver-mounted winch.
We have used Wrangler NW Power Products in
the past and know they are of excellent quality.
e decided to install a dual battery
system with Wranglers trick battery manager and a high output
alternator. Wrangler makes a dual battery kit for just about any
vehicle, including most late models. Each kit can be customized to
your needs and your application.
battery kit for the Tahoe was the Chevy - GMC 1996-1999 kit. Our
Project Tahoe already had a tray mounted opposite from the main
battery on the drivers side - most won't have this, but it depends
on the option packages from the factory.
Our vehicle also has the 105amp alternator, which is larger
than most. Most will have the 70amp alternator. We chose to upgrade
to the Wrangler Powermate 155 amp alternator which is mounted in
the same size case as our original but it will use an external
regulator. The Powermate alternators are constructed with premium
components. The Power Boss external voltage regulators feature
visible LED's for diagnostics. The regulator will show red when
battery power is on, green when ignition is on, and amber when
field voltage is on.
The regulators are compatible with the OEM
computer systems and come with a large finned heat sink to keep
them cool. The regulator also features a secondary main battery
sensing circuit so that the system will provide more accurate
charge rate to the batteries for longer battery life.
At the core of the dual battery system is the
battery isolation relay. You can use the relay alone or with the
optional battery manager kit. We chose to add the battery manager
kit which includes a dash mounted mode switch. The battery manager
definitely qualifies as "cool". With the battery manager you have
three modes of operation that can be controlled from inside the
This is the new Powermate on the left and our old
alternator on the right.
All terminals on the new Powermate are VERY clearly
