1990 YJ won't start

My boyfriend's 1990 YJ jeep wrangler wouldn't start this morning and after jumping it it ran. It also ran when we got out of class today, but an hour later it wouldn't start back up. We tried jumping it, but even though the battery says that the charge is fine, it's not turning over. The headlights, dash warning lights, and radio all work, and we cleaned the battery connectors and terminals, reattached them, and still there is nothing. There also isn't a clicking coming from the starter, so it would seem that the starter isn't getting power at all.

Could it be the solenoid or would it be something else? We're poor college kids and hoping to be able to replace the stuff on our own...thanks so much!

Sounds like the starter. Only a few bolts holding it on. Take it off and get the local parts store test it.

Nothing is foolproof to a sufficiently talented fool.

Does it make a clicking noise? If so, it`s probably your starter,
A couple of things you can try is to tap the solenoid with a hammer and see if it starts or climb underneath with a big screwdriver and use it to jump across your starter connections and see if it starts. If it does, check your battery cable connections and make sure they are gudntite (German torque language) and if they are,, well, you`re gonna have to replace your starter. If you are tight on funds, go to a pull-a-part if you have one. It`ll save you a few bucks.

Like above, if battery is good and battery connections are CLEAN and tight, check the connections at the starter, could be loose or corroded. Try the jumping with screwdriver at the solenoid as last resort, if that works, then solenoid should be the problem.

Also with that check the solenoid on the firewall behind the battery. Make sure that it clicks as well.
