Car battery died at a stop light
My 31 Tudor started up on the first crank and took it for a drive down the road about 2-3 miles and when I came to a stop light the car stalled and the battery was dead. I currently have no ameter in the car so I just figured the battery was dead. I tried to turn it in and there was no power at all. Had to tow it home. Why is my battery going dead once I was out on the road? Tested the battery when I got home and it only read 3.1 volts. I am charging the battery right now, but would like to hear any advise of what to do next. Battery is about 2-3 years old. Hope to get back on the road tomorrow.

Re: Car battery died at a stop light
Sounds like the generator or alternator was not charging. You were running on battery the whole.time until the voltage got so low, you finally lost spark.

Re: Car battery died at a stop light
You say you have no amp meter in the car. All auto electric, save for the starter, go through the amp meter. Did you Jump it there, pole to pole?

Re: Car battery died at a stop light
How long have you been driving with out an amp metor ? You can see f the generator is good by motoring it if it motors check your cut out but I do beleave that you need a amp metor to complete the charging system good luck let us know what you find!

After the battery is fully charged either install your ammeter or tie the two wires together, then start the engine. Run it at fast idle and turn on the lights. Leave the lights on and turn off the ignition. If the lights dim as the engine dies, then the generator is charging. This is a simple test which requires no tools or instruments. You can also just connect a voltmeter to the battery and see if the voltage goes up when you start the engine and run it to fast idle. |

Install an ammeter.

Hi Bruce When I bought the car it already did not have an amp meter, I have yet to install one. Not sure how it's wired. I bought the gage meter now I need instructions on how to wire it. The are 2-3 wires behind the dash the hook up to the gage just not sure what wire goes on what side of the gage. Would you happen to know? |

The yellow wire should be connected to the battery at the starter. So be careful that the bare end does not touch anything to ground it out. Best to temporarily disconnect the ground cable on the battery while working behind the instrument panel.

Re: Car battery died at a stop light
Remember that the Model A generator does not come with a voltage regulator, so any disconnect (open) in the charging circuit can let the generator go as high as 40 volts, which will quickly burn up the generator. A missing ammeter is an open in the charging circuit, unless you tie the wires together. Best to just install the meter so you can see what's happening.

Re: Car battery died at a stop light
any make/yr of car with an ammeter will require it to complete the wiring, not just an A. In simple terms it is a series device, tho it reads via a small shunt winding
Quite odd that the PO removed the ammeter. I am suspicious of some other problem lurking. Let's hope the PO did not burn up the generator by running with no meter
