You are quite welcome - just enjoy that K2.
There is one thing that I failed to mention, and that is your power supply.
The nominal current is about right for a power source of 13.8 volts. If
your power supply voltage is less than that - say 12 volts, the higher
current is to be expected.
The reason is that the K2 microprocessor attempt to control the power
output, and when the voltage is low, it still tries to produce the requested
power - Power = Volts x Amperes, so if the voltage goes down, the current
must rise if the power is to remain the same.
