Wiring Weirdness

I decided that im just going to run headers for the cam break in so I got around to undoing the y-pipe and seperating the headers from the rest of the exhaust. I set my distributor in pointing at number 1 *rotated the engine with the intake manifold off untill both valves were fully closed* and the timing marks on the harmonic balancer line up with the timing chain cover thing. Put the cap on, put all the spark plugs in, and wired them.

When I goto attach the battery, the starter engages and cranks over the engine. How many wires attach to each post on the starter? I have two on each, they are the same sizes too. I know there are three wires similar to the starter ones that attach to the back of the passenger head with a bolt. Im pretty sure I mixed up the wires, grounding the starter without the key being engaged, or something very similar along those lines. Can anyone help me out? Im kinda stuck right now and I dont know which wires need to go where now.

In other news:
I got in touch with a friend who has been in the army for a while.. his sister has picked up an 86 Iroc-z camaro. Its black, but really banged up.. she paid 1600 for hers and my car "which I paid 1500 for" is in a lot better condition. Shes got a 305 tune port in it. I told her about the message boards and she said she will get around to checking them out. So far thats three people in the past month that ive given this website too. Anytime you guys see third gens, you should take a piece of paper with the website on it and put it on there windshield I see third gens ALL the time in my area and most of the time they are driving so I cant tell them about the site.. if you have the chance to spread the word, do it

But yeah, can anyone tell me whats going on with these wires?

I beleive there is only one wire that connects to the small post that actually engages the starter- a small purple one with a small ring terminal on the end. Send 12V to that post and the starter will try to engage if it's got power to the main terminal.

I would ask others to confirm this, but I beleive all other wires have larger ring terminals on the end and connect to the same post as the main battery cable connects to.

I just checked my 92 RS and this is how it is.

alright, I have two wires with ring terminals on the small post *both of the wires ring terminals are the same size as the post*.. I wonder why there is two. Im going to tackle this problem either wednesday or thursday when my friend Jim comes over.

There are three wires with ring terminals that are attached onto the back of my head, should they be attached to the battery post of the starter?

Thank you!

The three on the back of the head are grounds. They should be put back where you found them- on the back of the head.

A second wire with a small ring terminal, eh? Someone else is going to have to chime in here. My 92 RS (original 305 TBI engine) only has one.

Alright, so i was looking at it..

I was wrong

There are two terminals on each post.

There is the main terminal that comes from the + of the battery, with its little buddy attatched to the smaller terminal. THEN I have these nasty dirty wires that have a metal heat shield around them thats also attached. Now im confused even more

separate all the wires, been there done that, your battery wire is leanin g against the solenoid wire, and when the battery cable is installed, it starts the solenoid and everything.

live and learn!

Those are the wires im confused about, I followed them back and they lead into a big T shaped bunch of wires.

Thats the heatshield that was originally on the wires.

I was looking at pictures of my old engine and I dont see those wires anywhere, but I dont have EVERY angle, I have some pictures of my engine removal but I still dont see them either.

Im at a total loss, The wires on the starter arent touching, im 100% positive. Once this problem gets resolved, my car will be running and then I can expierence summer the way its meant to be.

Anything that big has got to be a main power feed wire to/from something. In other words, it should go to the main terminal on the starter- same place the big + battery cable goes. The 2 siamesed wires with the big ring terminal on the end definitely goes there- there will be a little tab sticking out the back of the ring terminal that locks into a notch in the plastic end piece on the starter solenoid right next to the main terminal and prevents it from spinning as you tighten down the nut. The other one I can't see clearly- does it have a ring terminal on the end of it as well?

The heat shield is something you can do without if you don't want to put it back on. Many GM cars had one. I use it if it's convenient, but sometimes I get a car that somebody already took it off so I didn't worry about it. It's never caused me any problems one way or the other.

I can't beleive nobody else has taken a dive under their car to confirm some of this yet.

lol because its simple, there are like 3 or 4 wires on my car, the ones that goto the solenoid out(large terminal) have a big end, the one that does to the solenoid pulse wire, has a small end, its so easy, you can be on drugs and understand it.

If your starter is an autozone starter, then well, it has two small bolt, one is constant battery feed, other is pulse cable.

I still say when you tighened them up you connected the wires, they do have a tendancy to turn while you tighten, and you connected them, thats my story and i'm stickin to it!

The "bastard wires" that arent connected.. The big circle terminal is flat, has no hook to hold it in place. The wire coming from the + of the battery has two wires, a big terminal with a hook piece and a small terminal. I borrowed a VOM from my boss and hopefully ill be able to trace the wires out.

So 12SecondTA.. are you saying that three wires need to be hooked up to my starter?

I had the main wires coming from the + of my battery attached to the starter AND the "mystery bastard wires" and it still engaged the starter when I attach the battery.

Apparently not

My friend says that the + from the battery *small terminal* attaches to the alternator, is he right?

the one small pulse wire, makes the solenoid click... thats the only wire that can do this...all the rest are feeding power. If you hooked them up incorrectly certain things wont work, or will only work when the ignition switch is fully turned...

like i said before, something is connecting to each other....


i'll go outside and take a photo for you, hopefully its clear enough....

ok to make this simple.... i could see but ther camera couldn't get a good enough angle...

the purple wire goes to the small bolt closest to the engine...

all other 3 wires, connect to the large bolt furthest from the starter. You should never add anything to the starter side bolt, its what gives power to the motor inside the starter.

the other 3 wires car connected to the top, when above the car large bolt, and the purple wire goes to the small bolt closest to the engine...

OKAY! PROGRESS!

The + from the battery, two wires.. big wire going to starter.. smaller wire going to alternator bolt.

Nasty wires = Big terminal going to big terminal on starter, smaller wire attaching to smaller post on starter.

attach battery... NOTHING! sweet.

okay.. I open my door, LIGHTS ARE ON. *happyness*

I goto start the car.. turning turning turning DAMNIT.
I have a new camshaft in the engine so I dont wana damage it trying to get it running. DAMNIT

set your timing, and prime your carb!

aim the rotor towards to #1 bore, and stick your cap on, start it, set your timing, and run for 25minutes at 2500+rpm....
