    Alt. signal wire

    Well, I was in the engine compartment finishing getting the conduit back on the alt. wiring and got to looking at the new amp gauge wire at the junction block. I had followed the schematic and installed a #16 black wire from the #12 red alternator wire to the junction block as the "fusible...

    Alt. signal wire

    I was thinking last night about the wire catching on fire. I have been really reading that section in the factory maint. book on the alternator and working hard on comprehending what various functions are the alternator has. I've rebuilt that alternator many times ever since I've owned that...

    Alt. signal wire

    @SirRobyn0 , Oh my god, ha, ha, ha! I like that word, "vomit" I can see that in my minds eye. Well, good luck. Find the schematic on you Jeep and I suggest you do what I did and that is take the book, or print the schematic and take it to a print place and have them blow it up big enough so...

    Alt. signal wire

    @SirRobyn0, I'll finish putting the conduit back on the engine wiring tomorrow and then I go inside to repair a couple of the wires that got scorched. Also I'll make up a wire I can use to double check that alt. signal wire coming from the alternator into the engine side fire wall wire block...

    Alt. signal wire

    @SirRobyn0 Know what this is? I had to look it up. This goes in the alternator (below photo) on top of the voltage regulator. It's a resistor with fine little wires wrapped around the body, to provide resistance to make the alternator energize the field winding's in place of a light on the...

    Alt. signal wire

    Here's what I did today. I followed the excess wiring I don't need anymore. The less wiring to have something go wrong the better. Below is what that splice looks like that comes from the alternator, and in ya'll's case goes into the engine compartment harness. There are three wires: center...

    Alt. signal wire

    @SirRobyn0 Well, today I went out to the truck and after climbing into the engine compartment, you know some of our truck you could stand down on the ground, ha, ha, anyway and took all the old corrugated cover and old electrical tape off in places enough to be able to remove the conduit so I...

    The photo below, now you have to orient yourself to the picture, the right side is the bottom of the wire block going towards the floor, okay? Lean your head to the left, ha, ha. The pencil is pointing to whats left of the alt. signal wire. The light green wire to the right of it is the right...

    Alt. signal wire

    Well, let me see if I can remember how to load photos. Here's what happened to the 12v wire as soon as I tried to pry off the boot. Suddenly the whole wire came with the boot! I know it's a bit blurry, new camera I'm getting used to. The photo below is of the alt. signal wire that fried...

    Alt. signal wire

    @SirRobyn0 Thank you. Today I studied the wiring schematic some more trying to understand the relationship of the alternator and the other systems together. In the starting system should only involve three components, the battery, the starter, and the ignition switch. The alternator doesn't...

    Alt. signal wire

    @SirRobyn0 Man, thanks a lot!! I was considering changing out that alternator, I have a new spare, put it in and see what happens. And yeah, I did do a continuity test and it was good. @SquareRoot, Huge thanks! I was thinking of doing the same thing by removing it and see what affect it had...

    Alt. signal wire

    @SirRobyn0 Read above posts on strange wire fire and tell me what you think. So, me and my son went out to our local wrecking yard today to see if I could find a car or truck around my year, '74 C10 to see if I could find that alt. signal wire I could get. They had, to my surprise, a '75 Monty...

    @Randy De Oreo Yeah, thanks. And with this latest problem I'm back to having to deal with what was done at the factory back in '73, because this truck was purchased by the first owner, in Nov. of '73, '74 new model year. And whoever it was at the factory did a lousy job in wiring the truck...

    Alt. signal wire

    Have you seen how small a #24 wire is? The wire coming from the alt. is a regular #16 multi strand wire. The #24 going up to the ignition switch, which I can't see has much of a application in a 12v system, is a single copper wire. It measures .015" in diameter. In the stock instrument...

    Any tricks to thread speedo cable back through grommet in firewall?

    @tadkingnkc And if you can't get the bell through the grommet just take an exacto knife and split the grommet and do what @scrap--metal said. Sometimes it's easier to just go ahead and split it than try to shove the bell through the grommet. Of course it depends on how old the grommet is, and...

    Alt Light addition

    @jwgreen I had the light when my dash was stock. The light is part of the integrated circuit board. In the gang plug in the back of your instrument panel will be a #24 brown wire coming into the gang plug from the bulkhead block behind the fuse panel. On the other side of the bulkhead block...

    Loose unused 2 wire plug near steering column

    @ T The neutral safety switch wires in my truck which came with a TH350 are drk. green, light green, one goes to the back up switch and lamps, and two purple wires, one goes back to the ignition switch. Are you saying yours has both?

    Alt. signal wire

    Last night I posted a problem I had with the alternator signal wire up on the ignition switch frying, like it must have caught fire because it was melted to a bunch of other wires it was touching in the bundle. Well, they are mostly all okay after I had a chance to unstick them yesterday and...

    HotRodPC@ I went on that sight for the connectors looking for a tool to take a couple of pins out of the ignition switch plug but all they had were the water tight plug pin extractor. Then i saw a catagory called Packard 56 connector tools and yeah I do have some of those kind in the truck. I...

    KingBowzer@ When i rebuilt my '74 C10 i looked at all that wire running across the top of the engine going to the starter and thought, " Man, there has to be a better way!" So I got a piece of fenolic material, made a terminal block out of it with all the appropriate bolts and screws for the...

    The other day i used a little air compressor I bought you plug into your cigarette lighter, okay? (That means there's a story of a screw up coming.) I couldn't get the end onto the valve on the inner tube to use it although I did turn it on for a few seconds about three times then gave up...

    I did a thorough search on the web, i.e. Echler's, Classic Truck, Classic Industries, and Ebay, PartsGeek, and a dozen other after market sites and they're all the same. Some more or less expensive than others. I think I'd have as good luck at Advance Auto Parts and at least I wouldn't have to...

    @Turbo4whl Thanks! Well, I went on the Casco site and it wouldn't pull up, it said the way they created the site wouldn't work. So I clicked back and there were a couple more but when I clicked on them it bumped me around until it ended up on a Advance Auto Parts site. So I just typed in...

    Besides I don't even use it to light cigarette's, I use my Zippo. I use the lighter socket for USB power whenever my grandkids are in the truck. And you know their cellphone batteries are always about dead. I've got one of those car charger things with two USB's. But occasionally I do use...
