Default Some thoughts on fixing my starting problem (Now fixed)

So after doing some research it looks like I need to rewire my ignition system, sort of. I am going to run a new positive to the starter, a little smaller gage than is there currently and a connector that more closely fits the post on the starter. I also guess I need to hook up grounds to the engine. Can anyone explain what this does or why it would cause a problem? I also guess I need to figure out what the little black wire coming off my starter solenoid does and hook it to something. Also there is a positive wire that connects three medium gage wires directly to the battery however it is notably smaller than any of the three. I will probably run a pigtail off of the starter wire to these (I hope it works).

Lastly I have heard about running a relay off of the ignition switch in case the thing isn't delivering enough juice. Is this a good idea? How would that work? I know fukc at all about electrical let alone relays.

Thanks

Bryce

Just an update cause I have to vent. There is one bolt left holding the crossmember on and the tranny in. Their is a nut or something welded (well it used to be) inside the frame that has broken loose and is just freewheeling while I am turning the bolt from the other side. I'm not sure what all I can do short of cutting the head off the bolt which is my next step. There is not access from the backside or I would just try to grab it somehow. I think I may try to get the bolt with a sawzall prior to going at it with my cut-off wheel since that will take a fucking hour with my tiny compressor.

End rant

Default You ever do something dumb knowing the outcome but feel compelled to do it anyway?

So there was the one bolt left and after grinding on it quite a bit the crossmember slid down a bit and left a gap above it exposing the shaft of the bolt to the blade of my sawzall. So sure enough the bolt was the only thing holding the whole shebang there and when it let go the trans/transfercase fell, it didn't hit the ground because it was caught in mid arc by the shifter. So I got it jacked up and out of there and will now begine the process of putting in the new clutch disk and pilot bearing (if I can get the old one out that is) Anyone have any tips on pulling the pilot bearing? Anyway, I hope to have the clutch done today and might get the tranny back under the truck but I won't get it fitted up/bolted in until tomorrow night at the earliest, especially since I have to go pick up some new bolts.

Basically, for the starter, there's 3 'wires' to it.. well, 3 paths that current flows..

The first is the small wire, that goes to the little tab/spade lug on the solenoid attached to the starter. That is basically a low current (couple amps, maybe) wire that when energizes closes the main battery connection.

The second is your battery wire, thats the big wire running from your battery to your starter, it has a ring terminal and is secured to the large stud with a nut. That supplies the actual many many amps that turn the starter.

The third is the ground.. so where the wire, right? The starter is grounded to the metal case.. which is grounded to the transmission.... which is grounded to the engine.. which is grounded to the frame, which is grounded to the battery. So, thats why you need a good ground from the engine block to the frame and from the frame to the body(as well as the body to the frame, and the cylinder head to the body, etc)..


Its a good idea to spend a few (and I mean a few, its not very expensive at all), to go and replace the battery and ground cables that bolt onto the battery. Check and replace as needed the large ground and starter cables if they aren't in good shape.

Allright what I am thinking is that I will totally replace my positive and negative battery cables, the ground strap from the valve cover and the ground wire that runs from the frame to the block. My battery is located in the bed of the truck so I will run my negative to the same place the current negative is however I will try to get one with sealed ends, possibly from a marine store. I would like my positive cable also to be marine grade but I may just go to lowes for wire (I can't get a wire at an auto parts store due to the length). I plan to run the positive the same way it is currently but I am going to put a bus bar under the hood. One end of the positive will run to the bus bar and another wire will run from the bus bar to the starter. This will allow me to run a few new positives from under the hood rather than pigtailing the positive wire or running another wire all the way to the bed. Hopefully tomorrow I will get my tranny installed and I can start cracking on the wiring. I really want to drive this thing a little bit before I have to start driving loads out to NY.

If you have your old cable, or the kind of ends you want, welding stores have good heavy gage wire and various crimp or solder on lugs available. Just an alternative if you can't find what you want.

Cool I will definately keep that in mind in case I can't find what I want at west marine.

Anyway, I just got back from murrays and both of my starters are working so it is definately in my electrical system somewhere, now I just have to track it down.

As I said in my "pub" post, I now have the toyota running. Thanks for the advice and the offers for help, it was all greatly appreciated. I now have about 27 other things I have to do before she is road ready but I am honestly going to try to get about 20 of them done in the next two days. Anyway off to bed (fucking insomnia)
