Relay modification Headlamp and Marker lamp *pls review
Reply #13 –
Ok has anyone actually tested the voltage drop in the headlights with the stock wiring??? I have and it nothing to worry about. And does everyone realize the draw down is only 6A low and 7 A high per lamp . Not exactly a candidate for a dedicated battery feed condition. I would suggest testing voltage drop before designing circuits that are over the top and messy as well. I slave the switch contacts which is needed because the switch is the issue and the week link in the system not the wiring. And it does not interfere with FTP. It has it's own relay . if connected properly. Its neat clean and simple. Basically we are talking about a device that draws small amounts of current in comparison to other devices. Dont over-design circuits. It complicates it and it adds way to much wiring and is not necessary. Just My $.02
Note you might want to reconsider the relay locations under the hoods. Here is why!!!
