REFERENCE INFORMATION

The lights are the only circuit on the vehicle

which should work or be drawing any power

when the switch is in the STOP position.

Check the instruments,

try turning on the

heater fan, listen for any relay clicking or

other sign (includes engine running) that

power is on when it shouldn’t be.

It’s best if you use the STEKE-R

in TK mode

to verify that there is no current draw from

the batteries.

You can’t use the DCA mode for

this because it will measure this current

during the calibration part of the test and

read that this is just an offset in the sensor.

The lights should work with the

rotary switch in any position.
