Wont Crank/ No AUX power for anything!

This is my first project car and im strating to get frustrated, i need advice!!

I am working on a 1984 CJ7 4.2L 258 recently it just died on me wouldnt start up, so what I did was order an HEI distributor thinking I might as well get rid of the computer all together and elminate that problem (at least thats what i was told i could do?)

I have replaced the following:

Fuel tank
Starter
Temp sensor
Solenoid
Battery
Battery cables to solenoid/ to starter from solenoid
HEI distributor
Spark plugs
Spark plug wires
Fuel Pump
And i have a new CARB coming tomorrow

My issue now is that it will NOT crank over whatsoever and I have no power to anything, headlights, turn signals, wipers, Nothing! and I cant for the life of me figure out why. Everything is new.

However before I installed the new HEI I could at least attempt to crank it over (nothing would happen, but it would try too) Not sure if i had power or not then, it was kinda sitting for a week before I got the HEI and didnt really notice.

Ive had many people tell me they think its the Fusbile Link, whats your opinion?

And if so any good explanation as how to replace other then follow the wire and disconnect and replace with a new one, or is it just that simple?

Or could it be something else?

Someone please help!!

Just a reminder there is NO longer a computer.

Thanks a bunch,
NICK

Get a test light and start crom the begining. Make sure you have 12v at the battery if so the. Check at the positive side of your solenoid. See what you got.

It really is that simple!

There are two fusible links, one between the alt and the battery, and the other between the battery and the rest of the harness. They actually make a "Y" when connected, with the common end at the starter solenoid.

Are there still at least 2 smaller wires(not cables) hooked up to the soleniod? One attached to a smaller post labeled "s" is the actuator wire for the starter. You can take a short peice of wire from that post to the positive battery terminal with just a quick touch to see if your major parts are hooked up correctly. If you can bump the starter with that, then move on to the smaller wires that should be connected to the solenoid post that the battery cable connects to. That is the wire that carries power to everything else(ignition,aux.,lights) Follow it into the jungle(harness) and go from there.

I am going to test all my connections and make sure they are getting power.

Assuming it is the fusible link, what do i need to replace that? just the lead wire and the part the connects to the solenoid terminal?

I did not see ignition module in that list. I had the exact same issue with my 83 when I first bought him. Replaced the Solenoid nothing, ignition module and pow back to life. Its mounted under your washer bottle...I moved mine to the firewall when replacing it. Less than 25$, but sounds like you have another issue now.

I was told that when useing an HEI distributor you do not need the ignition module, or is that a false statement?

The gentleman that i ordered from said buying and HEI replaces your computer, ignition switch, module, and obviously the distributor.....

Does anyone know if this is true or false?
