Max. safe current draw across stock 36 Ford ignition/ on-off switch?
I’m building the wiring harness for my 36 coupe, which is 12 V negative ground. Stock flathead powered, power-master alternator and starter, and electric fan via a fan relay. Headlights TBD. Also an under-dash Arvin heater with 12v fan. I’m guessing with 12v power my current draw across the stock on/off column drop switch won’t be a problem, but figured I would ask those who have been down this path before. I know I can add relays and or an additional master on/off switch for devices powered by “ignition” (aka not constant 12v) power, but it’s simpler to just put them all through the stock switch if it’s robust enough. And simpler is always better.
Thanks!
Pat
