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!
