how many loads can a single standard automotive relay handle?
I guess what I'm asking is on the 87 pin how many loads can you attach to itWhat do you consider "typical"?
This one, for example, can carry 50A on the NO contact and 20A on the NC contact.
You can add as many loads as will have a total current of no more than 40A for the NO (normally open pin) or 30A for the NC (normally closed) pin.I guess what I'm asking is on the 87 pin how many loads can you attach to it
Awesome thank you that's what I figured because its really just a switch but it never hurts to askYou can add as many loads as will have a total current of no more than 40A for the NO (normally open pin) or 30A for the NC (normally closed) pin.
Ok so no fuse on the switch side then?Typically you fuse for the wire size to prevent melting the wire or its insulation in case of a short.
Thus the smallest wire gauge on the relay will determine the fuse size if you have only one fuse on the power going to the relay (pin 30).
Here are some typical maximum fuse size recommendations versus wire gauge.
It's fine to use a smaller fuse for a smaller load current.

If you use the same wire size to the relay as the reverse wire, than the fuse to the reverse wire should suffice.Pin 86= trigger but what size fuse for this?) connecting to reverse wire
Are you talking about just using the factory fuse so basically if I use same wire on relay than i don't need to worry about fusing the 86 pin cause the factory fuse will suffice? Sorry I just want to understand this correctlyIf you use the same wire size to the relay as the reverse wire, than the fuse to the reverse wire should suffice.
Yes.Are you talking about just using the factory fuse so basically if I use same wire on relay than i don't need to worry about fusing the 86 pin cause the factory fuse will suffice? Sorry I just want to understand this correctly
In the picture is maybe my dilemmaYes.
I'm assuming there is a factory fuse for the reverse wire, so if you use the same size wire to the relay coil, the factory fuse will protect the wire.
Now the only question is where do I get a schmatic at for a 2013 Dodge Charger reverse light circuit I think it should be ok a lot of people that I have seen run only a fuse on pin 30 using a fuse tap and just run all the other pins the same as usualBoth fuses do not go to the same circuit.
You will need the vehicle schematic to determine exactly where each goes.
A 5A fuse on pin 87 should protect all the relay circuits.
Like this oneNow the only question is where do I get a schmatic at for a 2013 Dodge Charger reverse light circuit I think it should be ok a lot of people that I have seen run only a fuse on pin 30 using a fuse tap and just run all the other pins the same as usual
It's basically just running a backup camera and 4 sensors and a LCD mirror totaling = approx 2.1 amps all on 16awg wire
That's for a 1996 caravan thoughAnything like this?
