I'm running electric fans on my LS swapped 80 series. And they pull alot of power - nominally 25A, but they pop 30A fuses. Uncomfortably close to the limit for the run of the mill 30/40 relay. a thought confirmed by some forum posts indicating relays weren't lasting to long with this fan.
So I picked up some heavier duty 80/60 relays, which also happen to be waterproof, meaning that the pigtail wires are sealed into the plug.
Which brings me to the question. Pretty much every relay wiring diagram you find shows the battery on pin 30 and the load on pin 87 (Normally Open). Example:
This leaves pin 87a (Normally Closed) hot when the load is not in use. I typically just de-pin the 87a wire from the pigtail so it can't flop around and short out. But that's not so easy with this unit.
I could just tape up the end of course, but electrical tape doesn't last forever. So I was thinking, why not wire it "backwards" and put pin 30 on the load side and pin 87 on the battery side. That way 87a is never hot.
Electrically, it should be fine of course. I just wonder if there's something in the mechanical design of the relay that will make this prone to earlier failure or such.
