The figure shows colors and polarity of the car lighter adapter.
The adapter has a little lamp (LED) that turns on if the car is
correctly providing the bracket with power.
If the lamp is off:
• verify that 12V voltage is available from the lighter plug;
• verify that the adapter internal fuse works; open the adapter
and check the fuse.
If the fuse is broken, replace it with a fuse with the same
electrical features. DO NOT USE ANY BY-PASS CIRCUIT.
The fuse guarantees that the special protection circuit inside
the plotter works properly under accidental short circuits,
polarity inversion and overvoltage.
If you have to remove the lighter adapter, the internal
connections are the following:
red (or white) + (+ 12V)
black
- (ground)
