Observe the LED lights on the TGX to verify the unit is receiving power.
If
any
LEDs turn on, the unit is receiving power; you do
not
need to review Table 5.1 below.
Instead,
If
no
LEDs turn on, the unit is
not
receiving power. A checklist is provided below only for use by
professionally trained automotive personnel. For assistance

NOTICE:
Only professionally trained automotive personnel should investigate, identify, and remedy any power-related issues,
working in a nonhazardous area, using safe practices and equipment.

On
Check power
plug and “hard boot” the unit
Check the power plug where it connects to the back of the TGX to ensure it is fully inserted
and its locking prong is firmly in place. Recheck the LEDs; if no LEDs turn on, try a “hard
boot”:
•
Press down on the plug’s locking p
rong and remove the plug from its input.
•
Wait approximately 10 seconds.
•
Examine the interior of the plug and check its connector pins.
If the plug and its pins appear
undamaged
, reconnect the plug to its input on the back of
the TGX, pushing the plug in until it clicks. Wait. If the power LED does not turn on within
approximately one minute, complete the remaining power checks below.
If the plug or its connector pins appear to be damaged, the power cable may need to be
replaced. Remove the unit from service and contact Industrial Scientific.

Fuse check
Visually inspect the red and white wire fuses for the correct fuse size and evaluate the
condition of the fuses.
•
The
red
(battery)
wire’s fuse should be 5A.
•
The
white
(ignition)
wire’s fuse should be
1A fuse recommended, 5A (maximum).
If a fuse is
not
of the amperage noted above, replace it with a fuse that is.
If a fuse appears burned, check the wiring from the vehicle battery or ignition to determine if
the wire has shorted out or been otherwise damaged.
•
If the wire is
not
damaged, replace the fuse with one of the amperage noted above.
