  post locked   1976 Torino electric dies while driving  

have 76 Ford Gran Torino with a 400ci/6.6 l and while I’m driving sometimes everything dies. Radio, dome light, everything. Ignition switch I was thinking, but the dome light going out to has me wondering? Not sure if it’s hot temperature wise, the motor isn’t overheating, but it seems to happen on hot days? No noises prior to dying. I let it sit for 5-10 minutes then the dome light comes on and I’m able to crank and it starts with no issues till the next time?

How about the headlights? Are they going out too?

Never checked? Everything goes out inside. I’ll check next time. You have an idea?

It helps isolate where we have to look and cuts down the number of possibilities.

Trying to remember - sorry so late to post:\
Owned one and a similar one with that engine both 1973. Look at battery negative cable. Now it sounds out of chance but could be original and still good! Either way the neg's large gauge goes to block and a pretty heavy duty one right to fender or metal fender well right away came with the OE battery cable end.


That never went wrong OMG they were this old but it would be a major source of ground for anything body on this thing as a chassis car make sure that is also testing strong ground.
OK - other is the box over by driver's side hood hinge is the attempt to call this all electronic with tons of wires. See if messed up and plugged in well try not to bust that or any connector. Wiggle test see if you snap it out of this mode.


I'm serious it's obviously a serious long time ago that box would blow on new cars all odd things came of it. If good they lasted forever no fix it's sealed inside with a plastic Jello stuff. I seriously doubt it would be intermittent but now who knows.


Was a very costly thing now if you found a used one you needed to know the color of the plastic where it plugged in by memory was either yellow or blue on same cars IDK why but wanted the right one or wouldn't run at all.
This car was almost identical to also an LTD Elite or just Elite I think or check Fords have mood swings what to name the dang things. There was a Merc. Cougar was really the same car too right there so those should really be the same car.
Heat related? Also look for anything close to exhaust system this car came with a converter full of pellets did get hot as all get out burned carpets inside car wasn't funny so would have been dealt with year one when new which I was doing for Ford at the time plus just a year or two!
Sorry for the novel that was a real early job hard as all hell to fix new cars with anything wrong at all but they sure did was hunt and seek out what new something wasn't right is harder than some history to me.
Last is wiggle grounds (find many) most bare braided things all vehicles use make sure you don't find broken ones still more likely trauma than rot but not the bolts or eyelet ends,


Tom

? Does that mean down to only headlights aren't working? Check at sockets behind bulbs. 2 outer are 3 wire (1 is ground, one is low only, one is high beam in one bulb) the inside has two wires, (one ground the other power) only has power on high beam request from button on floor left when headlight knob is pulled fully OUT to max.
Start at the bulbs OMG they ALL could lack ground to body I think. Find and fix that. If power next maybe the floor switch - pull carpet or rubber flooring back see how that's fastened I think 3 lag bolts to floor metal. It plugs in at that thing too to check for power.
Onward if all fuses (should have ruled that out a while ago) were good headlight's dash switch comes out to check pull it out then go underside a ball or thing sticks out if you push that the whole triangle knob will come out and can remove that whole switch - that enables more testing and or replacement.
Most will forget that know out and pushing the lump on the side hidden or can't remove it! The rest unscrews outer rings - near sure it's like that just memory,

OK, the fact that the headlights went out too means you can eliminate the ignition switch and everything related to it. You have to go back to the main battery source to look for your problem. You have a connection problem somewhere at that end. Start with the battery and remove and wire brush all connections. Then move onto the other end of cables and power feeds into the fuse box. Look for any burnt contacts or connections.

True HT, main power lost anywhere but thru firewall a chance. At the age open book exam here. A maybe all bulbs blown over some time possible erratic voltage applied or some fool thing.
These should have power all the time keys or not nothing to do with ignition as you said. Can be left on easily and not know it.


Still available high or low beam (4) light round. Test with jumper to any bat on workbench even see them work old or new.
Life by run time unknown then and now in hours ON usually, T

Tom, there is nothing wrong with the headlights. I asked him earlier if the headlights went out also when the dash did and he was merely answering my question.

Missed that. Hope he can still read how and where to deal with switch at floor and dash. OMG folks didn't know then. You can and will need to remove floor buttons get wet (any location) lube and work them every 10 years - OMG it has many decades on it! Tom :-)

K thanks again boys. I replaced the coil, module and solenoid. They were original so maybe that will fix it? Time will tell

You are in to this so I suggest keep old parts if it didn't fix anything go back or have part #s or just pics of what for later. OLD stuff on this would outlast most cloned junk so beware of new being better! "STUFF" electrical was real copper and brass, lead (Pb) where needed has no life expectancy. Zinc stuff does and plastic took a dump too.
Areas of trouble were lack of painting in unseen areas new as if save a buck per unit the payback is trouble spots of problems forever after IMO.
Whole point is save certain old parts you may be able to fix some better than what you'll get now! Bummer, Tom

Replacing those parts is fine but there is no way a coil or module can kill the headlamps or accessories.

Most likely a loose or dirty connection at a battery terminal or at the end of a battery cable that connects to the starter relay on the passenger side inner fender, Or where the negative cable is attached to the engine OR a bad ground from the engine to the body and/ or frame.

Those older Fords had a lot of problems with cable connections at the solenoid and the starter. You have to wire brush the cable ends.
