now power anywhere

I just put my engine back into my 86 k5 blazer and after hooking up all the wires in what I thaught was the right order i tried to start the motor but there seems to be no power getting to the starter. The headlight don't work, dome light or any internal components. I suspected that I hooked the wrong wires up to the alternator. I plugged a white coupler that had a red and brown wire in, that one is obvious. The main wire from the battery to the starter is also connected. I put the pink wire on the sylenoid for the ignition. There is a red wire with a balck rubber boot on the only post for the alternator. This is all in order, but there is a three red wire connector that I'm not sure where is goes. I had it on the back of the alternator, but according to my manual there is only one red wire connected there. It looks like it would go on the same post as the battery wire would to the starter, as it is the same size connector as that post is. Would this be a correct assumption? Thanks, Todd

Is the battery good? Not having wires hooked up to the alternator wouldn't cause you to have no power. Do you know the ground is good on the motor? On my 86 Silverado, I ran a cable from the negative battery post to the frame, and another from the frame to the alternator bracket. Cranks better now than it ever did.

The single read wire on the back of the alternator goes to the positive battery terminal for sure.

The single red wire is part of the wiring harness that goes into the cab area

I think my problem is the three red wires into on connector that is too big to be on the alternator but dosn't seem to reach that starter easily as I think it should. But, it is the same size connector that the positive battery wire to the starter!

"three red wires into on(e?) connector". Does that mean they are crimped into the same connection?

If they are, get an ohm meter and connect one lead to the connector, and the other to the battery negative. If you have low resistance, they probably were bolted on to the alternator bracket as a cheap replacement for the stock ground wire. Just because the wires are red, doesn't mean they have to be hot.

yes, three into one connector. I don't think it was connected to the alternator because the size of the connector is to large for the nut on that post to keep it in place. I just went and checked again and the wire in question is dirty and oily like it was around the bottom of the engine. The other wires around the upper part are clean so I'm thinking that it was connected to the starter some where. Dose that make any scense?

Makes sense, but it could have gone to the block as a ground. Follow the wires and see where they go.

Well i tried to trace the wires but they all go into the main wire harness that connect to the fuse box on the firewall. After loking at my manual it says that there is also a red wire to the starter. I'm wondering if I have the wires mixed up. If I remember from a long time ago, there were two wires connected to the starter solenoid that I had a hard time removing when I had to replace it a few years ago. It just dosn't make sence for it to not have power when the battery is good. The battery ground is good. You mentioned the motor ground are you talking about the weaved mesh style one on the back of the motor? If you are that one is good also.

I think you should have a friend over to help you out.

You are just looking to blow up your electrical system when you don't know what connections go where.

Get someone over to help you with it or take it to a shop and have them connect it up.

It might prove to be cheaper than damaging crucial components due to lack of knowledge.

I went on my hunch and put the connector on the battery terminal on the starter like I thaught it would go because of the size of the connector and low and behold it was right. It started right up and I just had to adjust the timeing and it purred like a kitten. I guess i should have sat down and looked at the manuel a little bit closer. Thanks J-Ri for the help. You helped me out a lot.
