Hey everyone,
The wiring courses don't really talk about inductive loads, and flyback protection, but as I continue to design my harness - I could see this possibly being a large problem. Maybe it's not that big of a deal with the modern electronics, and many ECU's / PMU's, but I want to make sure that I'm safe here before building the actual harness it's self.
For inductive loads like solenoids and other devices like pumps, do I need to use an external flyback diode? From my research, sometimes the reverse voltage spike can be 60-100v in a 12v automotive environment, which will certainly fry an internal in the ECU. The courses however did not really talk about inductive loads, mentioning that it was out of the scope for the course - so maybe the overall idea isn't too complicated.
What about relays and the coils used to energize that relay, should I be using a diode for relays? What about large current objects like fans and pumps, that require 30a+, I don't think I'd be able to find a 60a diode for my fans.
Any and all help is appreciated, thanks!
