I just wired up these driving lights. I used a relay. Do I need to install an inline fuze? If so should it be between the battery and the relay? Or between the relay and the lights?

QUOTE(Elliot Cannon @ Aug 31 2012, 05:22 PM)  If so should it be between the battery and the relay? Or between the relay and the lights? Battery to relay. The reason to use a relay in the first place is the fact that the relay trigger current is very low. You'd run that off one of the existing fuses anyways. So you want to fuse the 12V supply from the battery to the relay/lights. (IMG:style_emoticons/default/popcorn[1].gif) |

you want to fuse the power lead from the battery that goes through the relay and on to the lights. . fusing the battery lead that energizes the relay itself will offer no protection if you have a ground on the wire to the lights. . maybe just semantics but rather be clear about it. .

Hmmm, let's see. Two lights (IMG:style_emoticons/default/poke.gif) Would that be one or two trips to the EM. (IMG:style_emoticons/default/biggrin.gif)

The fuse should be within 18" of the battery for safety.

Tom has done a lot of thinking about upgrading of fusing. Came up with a pretty slick design if you really want to get into protecting your electrical system. http://www.914world.com/bbs2/index.php?showtopic=141317 |
