The battery IS GOOD!

I assume that is what you are asking.

Not able to do much at the moment - we have company.

Perhaps this afternoon or tomorrow.

 

No was asking if you checked to see if the the battery was charging. You should see about 13.8v with the engine running. Im suspecting that is not at this point in which case you would see about 12v or less with the engine running.

 

Gun Jam: I just went out to start the '67 Mustang a few minutes ago.

Here is what I fght up!

Turned it off & back on a number of time, started fine THEN.ound: When I first sat in the seat, the over-head light was on. I then put key in & turned it on, IMMEDIATELY EVERYTHING went dark. Turned it off, sat there 15? seconds the over-head light came back on. Turned the key on, dash lights lit, tried the starter it fired right up.

 

well if sliding the key in the ignition caused the problem without even rotating the ignition barrel. Then its quite hard to ignore the ignition as a likley source. It seems that when the ignition was wiggled or touched as the key went in it something lost contact.

 

Gun Jam,

Please note: "Put the key in and TURNED IT ON" - it's the same problem as in the beginning. And I have replaced the ignition switch.

Is there a 'RELAY" (or anything similar) that might act in this manner?

I can't think of ANYTHING that might cause this. A relative told me that it sounded like a "ground problem" someplace. I don't know of any place MORE to check for that as the problem. Have checked the places that I know to check.

At this stage, I "fear" driving it up this road (live on a peninsula) and it is a narrow road with NO PLACE to pull off in many areas. Will be stuck in the road it it dies.

Thanks for your effort.

 

Yeah I wouldn't want to drive it too far either.

It could be a ground problem this is quite likely but again the system uses multiple grounds.

You seem to be a bit hesitant about the whole multi meter thing. If you need one this is the exact one I would recommend its quite simple due to "auto range" allowing it to measure 500mV or 12V or 150V DC without having to move the dial.
Not I, Yourself or anyone else can provide anything beyond speculation at this point without confirming feedback. Unfortunately in your case its electrical and complex enough that at this point we can only get the confirmation we need from a Multimeter. We could show you how to run simple test with it, There are lots of youtube videos on how they work and how to use them.

We could find a wiring diagram for something like headlights on line like this:

We can see that all those interior light feed off of the battery and its first stop is the solenoid. So the easiest guy here is the eng compartment lamp if you've got that. Does it go out? Wouldn't it be nice to know if power was getting to the Solenoid? IS it getting past the solenoid? How far past? Enter Digial multimeter
