When it comes to today's classic trucks, the amount of creature comforts being installed seems endless. Air conditioning, power windows, power seats, door poppers, and everything else one can think of all require more electrical power than most electrical systems and switches were designed to handle.

The big push to install relays to overcome the excessive loads on wiring and switches is a much-needed trend. Relays allow the power-consuming load to receive the current required without overloading the circuits and switches. These accessories will also perform at greater efficiency due to the increased power available.

Much of this is illustrated by Bill Marcom's '54 Chevrolet pickup. He was having starting problems and when the air conditioning was on, he smelled wires burning. Bill contacted John Roberts, a local wiring guy, to find the problem and make repairs.

Roberts examined the pickup and quickly realized that some relays and a little rewiring would have Bill on his way with much more confidence in his pickup's electrical system.
