2 Power Supply

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!
