So, like most of us with these ... “seasoned” trucks, I’ve been spending a lot of time straightening out what the previous owners “fixed.” From sketchy wiring to lack of maintenance, we’ve all seen it before. Today, I got the reverse lights rewired and tidied up some more of the unwanted “spaghetti” of unused vacuum lines under the hood and, on a whim, looked at the fuses.
Wow.
Now, none were blown, and the cover to my block is long gone, so I pulled up an image of the cover with the correct size of fuses.
None were right in my truck. I had 30s, I had 20s, I DID have a couple 15s, but I had NO 10s. Now, the wiring diagram we’ve got here on the site shows “15A” across all the fuses, but looking at several other images, it seems there are a smattering of 10A fuses thrown in (I’d guess it was based on the options of the truck?).
But no 20A or 30A fuses.
So if your truck is “new to you” this might be a good time to check and change - or at least make sure the right ones are in place. (It’s also probably smart to give your fuse block a good swipe or three with some emory cloth or even a small wire brush or even a bore brush from a gun cleaning kit.) This will give you good contact when you replace the fuses with the ones the circuit is rated for.
