Double Trouble by Dennis Overholser PainlessPerformance.com
When it comes to today’s classic vehicles, the amount of creature comforts being installed seems endless. Air conditioning, power windows, power seats, door poppers, power trunk 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 with out overloading circuits and switches. Due to the power increase available to the accessories, they will also perform at greater efficiency.
In the story to follow Bill Marcoms 1954 Chevrolet pickup was having starting problems and when the air conditioning was on he smelled wires burning. He contacted John Roberts, a local wiring guy, to find the problem and make repairs.
