Please ensure that you have a good ground installation. That means:
– A ground that has a solid, low resistance connection to the negative battery terminal
– Connection should be free from dirt, grease, paint, anodizing, etc.
– Use large diameter wire
– More metal-to-metal contact is better!
The following notations for power signals are used:
– KL 15 is a switched battery rail controlled by the IGN-switch
– KL 30 is an unswitched battery positive rail (same as battery positive terminal)
– KL 31 is an unswitched ground rail (same as battery negative terminal)
Be careful to observe current limits of wires and connector pins!
