McMaster-Carr has the meltwall heatshrink, ring terminals to fit the larger battery cables, the tools to crimp them with, and the heatgun to shrink the heat shrink down. Then again, I spent my life as a radar technician, soooo. It drives me nuts to see a cable with it's strands hanging out tangled around the bolt of a battery terminal. It also LOOKS much neater and more professional. Which causes troubles that can drive you nuts. The inner liner of the heatshrink melts and flows into all the interstices (big word for the day!), keeping battery acid from getting inside the insulation and causing the strands of wire to break back under the insulation, where you can't see it. THEN slide it down onto the ring terminal and shrink it down.

Yeah, I know, I should have told you to put the heatshrink over the cable before you crimp the ring terminal on. Cut the wires off the current terminal lugs, crimp a decent ring terminal on, and put 2" of heatshrink over it. They look just like the ones clamped on your battery now, but they have a screw post sticking up vertically. Which I know EMTs DO Switch over to marine type terminals. Speaking of, if you have a little time, which I know EMTs don't have a lot of, and the right skills. They even fit down through the battery terminal lug holes quite well. I don't know how many sets I have floating around. Steel, brass, ad nylon, with cheap plastic handles. For the steel parts, like the bolt and the hole under it, a steel brush will do it for ya.Īlmost every auto parts store I've looked in lately has these sets of three brushes for a dollar. Like I said though, for the lead parts, like the terminals, the terminal lugs that are on them and so forth, a brass brush will do the trick nicely, without unduly eroding the lead. Having said that, I would be concerned with the corrosion built up on that ground bolt. I just keep lots of paper towels on hand when I work on it I'm afraid the dirt and grease built up is all that's holding it together! I'm afraid the engine will fall out if I do, honestly. I'm not so concerned with the dirt, grease, etc. Not just the outside, "look-good" part, but the inside, where they wrap around the terminals out of the battery. Just a side note, clean those battery terminals real well. I cannot imagine who would cut that, unless they're really upset with you, or the truck. But almost no path for current flow for all the rest of the truck's electrical systems. From the factory, there's only two, that one, and the one going to engine block down on the AC bracket, that the starter, and various sensors use. Sorry, not trying to be bossy, but that's one of THE most important wires in the truck, however humble and unpreposessing it may appear. Fix that immediately!Ĭlean the bolt while you're at it. I could go on and on with systems that are affected, but you get the idea. Because of the head gasket, the head to engine block electrical connection is virtually non-existent. There may be other paths to the battery, but this is THE ground for 99% of what's in the truck. So many things are grounded to the body, it just amazing. Does anyone have any ideas? I'm stressing myself out over it too much, figured maybe a sensor or vacuum leak could be it, but didn't know where to start, didn't know if it could be a fuel problem, I wasn't in the vehicle so I'm at a bit of a loss. I am towing it to a local shop to have the CEL scanned monday night. I was driving it in stock trim while working on other projects for a month or so with no issues, my dad drove it to work, said just before he got there it started running a little rough, on his way home it got worse and worse, the CEL started flashing and it died on him, he was able to restart it, same issue and it died in the driveway and wouldn't start again. Bought a toytec/eibach lift kit, new wheels and tires and everything for the tundra brake upgrade. I replaced the valve cover gaskets, and plugs, oil change, with an oil treatment beforehand. I am a novice, but really want to improve my mechanical prowess. It needed a lot of work, some body rust (frame is good) leaky valve covers, suspension and brakes.

I bought a 1998 4runner sr5 4wd a few months ago, I want to build it and get it to my fiance as a christmas gift. This is my first post here, I apologize if this is long winded or against any guidelines, I can make any changes needed.
