I'll try to make this simple. I have an '88 YJ that's havng starting problems. When I go to start, seatbelt buzzer is loud and clear, and I have all internal and external lights/electcrical working fine. I'll turn the key and get a single click, then the car is dead. Seatbelt buzzer is very quiet and electrical is barely existant. Give it a little while and the power comes back, though I'm sure the battery is lower. Jumping it does nothing.
I have the starter relay that's located on the firewall. Do you suppose this is the culprit?
A little more back story...
A couple months back, I was cruising along on a back highway when the jeep simply cut out while driving. Again, all elctronics were working totally fine, but no starting, or even turning over. After digging around for a while on the side of the road, I discovered that one of the wires connected to the threaded part of the relay had eroded and came apart. So I simply desheathed some wire and crudely reconnected it.
Then, on the next startup, I smelled smoke. An inspection showed that one of the wires to the connector located below and to the right of the oil pressure sending unit. The sheath was completely fried off.
Unplugging the connector (I don't know what it is or what it's for) has allowed the jeep to run fine. Oil pressure gauge works fine.
The jeep has been running fine till now. I've been meaning to get it taken care of, but it's been on the backburner. It's a royal pain following wires in the big bundles. Anyone know any tricks for following or getting wires in/out of the super-stiff sheath?
So I've pulled the relay, or what Haynes calls the Motorcraft Solenoid off the firewall and will be trying to get another installed as that seems to be near the source of the problem and is a cheap swap.
But is this correct? What are all the wires coming off the mounting post that the battery is connected to on the relay/solenoid?
I'm a bumbling fool with this electrical system. Any help would be greatly appreciated. Thanks! Sorry for the big post. I just wanted to be clear.
