July 2013 Randy's Electrical Corner

I’m sure you have all heard about the guy who shot himself when his truck blew a fuse and he replaced it with a bullet. I don’t know where he shot himself. Sure, the story is better if the guy really can’t have kids anymore. Someone much smarter than me said something about a cleaner jean pool (Editor’s note: gene pool), but I don’t really understand how a guy not having kids can lead to clean jeans in a pool. Just sounds like a way to get soggy pants to me.

The old-school round fuses were used in Jeeps for a long time and because those Jeeps are older, the Jeeps tend to have more electrical problems than newer Jeeps. A lot of people blame the old-style fuses, but did you know that these fuses are also found in most 12V DC electrical plugs? If you have a low-amperage fuse that blows in your Jeep and a charging cable or power adapter you can often take the power adapter apart and put the fuse from it in your old Jeep.

Oh yeah, the point is don’t shoot yourself in the nuts with a bullet. Or anything else for that matter. No, wait, that wasn’t the point. Oh, the point was that your Jeep has fuses for a reason and bypassing them is bad, kind of like when Earl ran over the neighbor’s cat. Don’t kill your neighbor’s cat, replace your fuses with the same kind and rating of fuse as whatever the Jeep engineers originally said your Jeep should have.

Over the years Jeep used a lot of different fuses and it can sometimes be difficult to sort it all out. I’m something of a fuseologist. Next to relays, fuses are probably my favorite electrical part in a Jeep. They can tell you when something is going wrong in your electrical system, they can keep the Jeep from catching fire, and they can protect your electrical stuff from damage. The problem is that a lot of people don’t really care about fuses, fuse blocks, or inline fuses until it is too late and something is wrong.

You Jeep guys always going topless around this time of year and getting caught in rainstorms means that your fuses often get wet. I wish it was the Jeep chicks who went topless, that would be cool. Mmm, wet topless Jeep chicks. Sorry, getting off topic again.

I was saying you should inspect your fuses every now and again to make sure there are no problems that might mess with your electrical system. What kind of fuses do you have? What are the different sizes for? What kind of problems might you see? All good questions…read along.
