Ford FalconFord Falcon - With standard features such as the exhilarating 6-cylinder Barra 182 engine, Control Blade IRS (sedan only), Sequential Sports Shift (on the optional automatic transmission) and an Intelligent Safety System which boasts a multitude of advanced safety features, the Falcon XT is not only a driver's car. It's also a car that the whole family can enjoy.
My 60 Frontenac (Falcon with some Maple Leafs) stalled the other day. Battery didn't seem to be putting out enough power to crank well. I tested the battery and received these readings:
Turned off: 12.8 volts
Idling without accessories on: 12.5 - 12.7 volts
Idling with lights and radio on: 12.4 volts
The shop manual refers to test voltages between 9 and 10 volts. So, before I buy an ammeter to test the generator, I am wondering whether such readings are common and acceptable.
The readings kept dropping on the last two tests, maybe because the generator wasn't charging the battery while idling.
Phantom, cars from 1960 didn't have alternators, they had generators. One must keep the age of the vehicle in mind.
Winums, you need to check the voltage under load. Problem is you will need to take the car to the shop for the testing.
"Some" battery shops are still willing to do this for no charge but be warned that some think they have a sucker and will give you a false reading on the tests.
I had a battery shop and world famous Sears automotive both give false readings on the same day. Neither had noticed that the ground strap from the battery to car body was no longer attcahed to the body and without ground the battery won't charge. Both wanted to sell me a new battery and regulator. If I would have returned the next day they would have charged for something else as they were making money by guessing.
Some people, like myself, stillown the equipment needed to check cars pre alt. and electronic ignition. On my set up (Sears) there is a set up that attaches between the generator and equipment which has a method of adding the needed "load" to obtain the correct reading. I haven't looked at the recent home mechanic's equipment to see how and what has changed over the last 20 years so I won't suggest you go out and by said equipment.
But on the other hand, since your car still has a gen. and points it might be worth the price of having a shop testing the battery and charging system.
I will suggest that you add a simple VOLT meter under the dash to keep track of the battery's actual voltage/charging/not charging. AMP meters are supposed to do the same job but on the last three NEW Fords I have purchased none of the AMP gauges worked! On all three I have had dead batteries which would have been noticed/corrected if the AMP gauge worked.
I NEVER trusted Ford's "GEN" warning light either. I've seen way too many Falcons in which the lights had burned out bulbs because the driver didn't notice the light didn't come on when starting the car ("fail safe" design).
Thanks Yank with Ute. Looks like some of the equipment may be hard to find. The manual refers to a "high-rate discharge tester" to be used to test the battery capacity. The local auto supply stores don't seem to know what one is.
Thanks theoldwizard, the manual refers to running it at 1500 rpm for one of the generator tests and some related reading has also suggested testing the battery with a high idle. I think I forgot to run that test the other day. Thanks for the reminder.

You can approximate this by leaving your high beams on for about 15 minutes and then starting the car ! If you really want want, check places like eBay or Harbor Freight. They sell for about $25-$50.
