Relays

[EMR714]

Hey all. Can you recommend any good sources for relays? I took my trailer for a quick over night trip at a regular campground and 3 out of 5 have issues.

I bought my current set from Amazon. Pure junk. 4-PIN 40/30 AMP 12 V DC...
I have the relays powering a dometic cooler, water pump and two sets of diode dynamics LED pod lights.

Bosch - make sure they are real.

Every couple years I head to the local pick and pull and grab a bucket of older German Bosch production relays from BMWs, Audis, and Mercedes vehicles. All kinds of great relays saves frustration from modern knock off, low grade, and counterfeit Bosch relays sold different places on the web.

I've always used cheap ones from what ever auto parts store was closest. While I've never had any problems, I always carry spares.

Just curious...why do you have the cooler and lights on relays? Those don't draw enough power to need anything more than a switch.

Thanks for the suggestions everyone

Good question. Years ago I was told they add a level of safety. I suppose the idea stuck with me.

Lol... I was just curious. They are very low amp draw items.

Have you looked into the REDARC relays?

The RK1260 Relay Kit allows a BCDC to be installed in a trailer that is being towed by a vehicle that is equipped with a smart alternator.

Thank you for that link Art. While i have not used RedArc products, I have read nothing but good reviews and not heard of failures.
