Having to rewire my boat. I have Charlie Wing's book, Boatowner's Illustrated Handbook of Wiring
. On page 288, his first project
is the two lamp AC Reverse Polarity Indicator. He shows the "GREEN" part of the circuit as: Hot ->Resistor -> Lamp -> Neutral. His "RED" section is: Neutral -> Resistor -> Lamp -> Ground.
But Technical Brief "Reverse Polarity Indicators"
describes a one lamp system. It show the circuit as : Neutral -> Lamp -> Resistor -> Ground.
OBSERVATIONS: The lamp and the resistor's position are reverse on the two circuits.
Questions: 1. Does the position of the resistor make a difference?
2. Does having the LED vs. Neon Lamp make a difference?
p.s. Sorry I couldn't embed the Wing diagram, I couldn't get it to work that way. nb
