dc relay
 

Hey guys,

Having a brain issue. Are automotive relays bipolar? or are they polarized?

I picked up some cheap relays and there's no indication of a pos/neg pole on
the coil....I'm guessing it don't make a difference!

Re: dc relay
 

It don't, you are just creating a magnet to pull the contacts in.

Re: dc relay
 

What size are you talking the small 20 amp ones, like for auxiliary
lights? http://www.kchilites.com/instruction...layHarness.pdf You
may have to use the plus size in order to see the numbers that both
Bosch and Radio Shack use. The solenoid coil would be polarized, the the
power running through the points wouldn't make a nickel's worth of
difference.

Re: dc relay
 

These are rated 40Amps. $3 per at Princess Auto...I finally found the one
near me and had a chub the whole time I was there!! haha

I realized the points won't matter....there ARE numbers on the contacts
(5contacts...2-coils, 3-switch {n/o & n/c})....but these numbers don't lead
you to think ones pos or neg!
