The GLPS can be powered up
through its own battery power or
by using its power adapter and
connecting it to the vehicle power
supply through the NATO plug.
However, many GLPS batteries
have reached the end of their life and
no longer charge properly. (If you
charge a battery like it says in Section
II of TM 9-6675-347-13&P and the
battery shows a charge of less than
80 percent, the battery needs to go
to maintenance.) So the only power
choice then is vehicle power. And
that’s where the damage can occur.
The GLPS gyros are very sensitive
to voltage spikes from the vehicle.
The way to prevent these spikes is to
Frst shut off the vehicle before you
power up the GLPS.
And leave the
vehicle off while the GLPS is on.
