Ok, so the word to the solenoid seem fine.

I just tried to start...turns but doesn't fire...

The ignition is protected by a fuse link wire. This is a special chunk of wire that will melt before the harness catches on fire in case of a short circuit.

The fuse links have soft rubber insulation on them and are bolted onto the battery side of the solenoid. They are only about 6" long and have a big rubber covered crimp connector on their end.

It is common for them to pop if a boost caused a spark the wrong way. One oops, and it is done.

Pulling on them will show if one has blown.

I'm not sure what I'm looking at. Here are two photos.

And one of my Jeep, just because (I've got a small lawnmower tire propping up the bonnet).

On 'Black Betty' my '78 CJ5 the fuseable link is RED and runs from the Ignition Switch to the Alternator. This may be it here.




Yours may be the same, it'll look similar to these

Edit: With as crummy looking as that starter solenoid looks from the photos I'd keep in mind to replace it and wire brush/dielectric grease up all the conacts.

I am seeing a white wire coming off the battery cable side of the fender solenoid where the battery cable bolts on. This wire goes to a bunch of black tape and if it is the only one, it must feed both the alternator and ignition.

This is supposed to be a fuse link wire. Maybe it is crimped to the fuse link under the tape? How many wires continue on from this white wire?

Do you have a multimeter? If so I would turn the key to run, not start and see if there is 12 volts on the ignition coil.

Your fuse panel should also have a fuse labeled ign lps maybe, the later ones do, but check for volts at the coil first.

That is a starter solenoid/relay on the fender with what could be a yellow on it.

If that is the fuse link, then it needs a gentle pull on it to see if it has broken.

Ok, thanks to you all for guiding me.

Here are a bunch of photos of that taped group of wires.

I did pull on them and they're firm.

Here's a link to photos.

Those photos trace that set of wires, showing where they connect to the condenser and the carb then to the back panel. Then the wires under the dash.

There is a dark mark on that yellow wire, don't know if it is a burn though.

Can you do a power test on the coil terminals with the key set to 'run'.?

I need to get a multimeter. Lowe's is half mile away. Brb.

Here are photos of the fuses under the dash.

Jen,

The first post in this thread contains a detailed explanation of how to troubleshoot your ignition system.

http://www.jeepforum.com/forum/f8/je...-help-1092376/

Good luck, and keep us informed.

Matt

Ok, so the voltage to the coil when the key is on Run was only 5.9, of a 12V battery.

There were wires going in and out of a resistor between the starter, battery, and the coil. I pulled the wires out of the resistor and connected then directly together with electrical tape. After that the voltage to the coil said 12.

6VDC in 'run', is OK.
Run a wire from the POS(+) side of your battery to the POS(+)side of the coil.
See if it starts.
You'll need to pull the wire to 'kill' the eng after you turn the key off.
Good luck,
LG

I'll need to get some wire, I think. I don't imagine you can use any old wire.
