1979 351 cleveland Ford Ranchero... No power ..killing batteries

Son drove to school just fine. After school battery was dead..We thought? Tried to jump it and nothing..not even a click.... Tried to bypass solenoid...nothing.... Lights come on but wipers will barely move even with charger on the battery. I found a big gauge wire coming from the back of motor that has no insulation and is un hooked on one end...


Help me please.....
Thanks in advance

Follow your ground "-" wire from the battery to where it bolts up to the engine. Each end should be clean and tight. Next do the same with the positive "+" wire to the solenoid and the starter wire from the solenoid to the starter. Is the battery full of water? How old is the battery? Sometimes a battery will die internally so you may want to try another battery. The starter solenoid can be jumped with a jumper cable from battery post to starter post (the two big ones) to by pass it. Good hunting..

Exactly, and make sure there is a ground from the battery to chassis or engine to chassis which kinda sounds like the wire you are referring to.

Since you are jumping the solenoid, your components are your batter, solenoid, cables and starter.

All indications point to a bad battery or loose connection on your battery cables.

That would be the negative from the engine to the
cars body. Without that connection, you're turning
your cooling system into part of the electrical system,
this is bad...

Doc here,

Sounds like that bare wire may have melted off your fuse link...Check that wire and see where it goes (Like Ign. Switch) and check the fuse link to see if one of the three wires is missing...

To quick test the ground, just get your jumper cables, and hook the black to the battery ground and the other end to a good spot on the block and try it again....If it cranks you got grounding issues...

Doc

Thanks again for your help. Got sidetracked with my 1970 Chevy C/10. Dang timing keeps moving about every 2 months. I get a sonic boom and need a new muffler each time. I reset the dist. and all is okay until it does it again. Might need to replace the timing chain I'm sure. Those booms are scary.
