Question about 1966 Ford Mustang

2 Answers

I went to start my 1966 Ford Mustang and the battery was totally dead. I jumped it and it started. After running the car for about five minutes, I tried to restart and it barely cranked. The battery is almost brand new. Looking at the Altemeter, the system does not seems to be charging, but not at very high rates. What should I look at and in what order?

    Wouldn't the altemeter be charging at a high rate or level, if everything was working properly?

  • ekirby235 May 11, 2010

    I messed up in my original description. Looking at the Altemeter, when the dar is running, it does seem to be charging, but at a very low rate. I would think with a dead battery it would be charging at a very high rate or level when the car is running, until the battery is charged.

On a '66 once you get the car started, disconnect battery and see if car will stay running on alternator only. If not then bad alternator. If it will run then have battery checked (yes even if it is "new"). If ok then you are looking for a constant current draw on system.

    Concerning ammmeter, I don't trust them, charging system could be "iffy", if it is working then car will run without battery

Nothing in short....it takes about an hour of constant running to recharge a flat battery.

The 1966 Mustang convertible starts if jumped but not without. When turning the key it simply makes a clicking noise. Help!


Check the battery voltage, it should be 13.5V if it's fully charged. Charge it up if it's not and then try. When you have the car running check the alternater output to make sure it is properly charging the battery. This should also be about 13.5V.
It would also be a very good idea to make sure all your cable ends are bare shiny metal and fastened tight.
It's also possible you power cable to the starter is bad, or the ground strap from the engine.
I have occasionally seen where this has been caused by a faulty solenoid on the fender. If that is the case, then you should be able to short across it and start the engine.

IS IT THE BATTERY OR THE ALTERNATOR


Get a cheap digital voltmeter put it on the DC volts range. Place the red lead on the positive terminal of the battery and the black common lead on the negative terminal. Jump start the car again to get it running. If the battery reads in the range of 13.6 Volts DC volts then the alternator is supplying enough power to charge your battery. The alternator must generate more than 12 volts Direct Current to charge a battery. Also check the belt is not slipping on the alternator pulley.

Ignition problem... No signal from ignition to solenoid...run a starter draw test to confirm starter is ok --- You can run your jump wires to a remote starter button or switch to get around it for now.

Battery on a 2005 Mustang went dead. Had a Jump to get the car started. Drove & speedometer & odometer worked fine. However, I had Triple AAA install a new battery & now they don't work. ...


Did AAA clean the battery cable connections when they installed your battery? Did you check the fuse for the insrument panel?

It could be just bad timing or a coincidense but I am more likely to think things are connected. If your gauges worked after jump starting your car, but not after AAA changed the battery, something changed or was left disconnected.

okay try this....talk to your parts store and get a battery load tester, and find out if the battery is indeed dead. My guess is it sounds like the Altenator is dying. they are around 50-100 and can be install by a pro in minutes.
