Thank you! I've got way too many things spliced into my 12V behind the center console.

I'm not really that electrically literate, so pardon me if this is a stupid question, but how much can 10w hold safely? Will it provide sufficient and safe power to my GPS and CB?

 

More than likely it will be fine for the CB. I don't recall exactly how much a CB draws, but it's a couple of amps I believe. Look at the fuse for the CB or the current draw rating for what you are trying to power off of it.

 

SO will this safely power 55 watt lights? Would it power 2 setts of 55 watt lights?

 

No it will safely power your switch and trigger the relay (the green wire in the diagram). Run the big power to your relay straight from the battery with an in-line fuse of the size they recommend.

 

That's what I meant. If I was going to wire up two sets of lights, can I run both switches off of this?

I picked one up and it does not look like you can fit two of them in the fuse box. If that fuse was vertical, it would be alot easier.

Hey James,

The answer is NO.......... One Switch per Circuit . That means a separate relay. So find another tap somewhere in the fuse box or wire up a relay circuit .

EDIT: and stop trying to use 30 amps on a circuit only supplying 10 to 15 you fister.......

He could absolutely run both switches off one fuse tap. It's done everyday and there is no reason not to. Why run two fuses/wires when all you need is one. The relays the switches will control will pull about 150mA each, the switches will not draw any current unless they have a light on them and in that case most of those are LEDs and draw negligible current. In the case it's an incandescent bulb you're talking MAYBE a 2w bulb which would be about 160mA current draw. So even if he has two lighted switches powering 2 30A relays the current draw is less than 1A even with the built in resistance of the wire and all the connectors. That is well under the 10A the fuse holder is rated for.

 

Looks like I am too slow.

 

darn

It sure sucks each and every time you run into a thread that Photobucket has rendered useless by no longer hosting the images. I wanted to see this !
:nono:

:jeep2:

 

What do you need to see? I am running 2 of these little fuse adapters. I can get you a pic.
