Car won't start. Help!

One week ago, the Model A started and drove fine. Today, it turned over very slowly but started. The ammeter is showing zero charge. If I turn the lights on, it's showing about -10....so, I assume it's working.

I drove it around the block, wishfully thinking that all would be fine. As soon as I got back home and came to a stop, the engine died. Now, the starter won't turn.

The battery is showing over 6+ volts and terminals are tight.

Troubleshooting is not my strongpoint.

hello
sounds like generator is not charging try charging the battry or take it to a auto parts store and have them test the battery under a load with the starter it may not have enough power to turn the starter

If the starter "wont turn"... possibly the starter bendix is jammed. If so, put the vehicle in 3rd gear and rock it front to back then try the starter again. If that does not work, remove the starter and try engaging it again. Good luck.
 
Would a defective or stuck starter have an effect on the charging system? While I was driving, the ammeter was showing no charge.
 
A fully charged battery should have about 6.3 volts. You may have a poor electrical connection. Follow the wiring and check for voltage along the way. First at the starter, then at the terminal box, then at the points (with the points open and the ignition switch on. It could be a bad connection at the battery. check the cables. Good Luck.
 
A stuck starter will not affect the charging system. If the generator quit, the voltage could be too low to run the car, so make sure you have at least 6 volts with a draw, such as the lights on..... Do the lights work, Horn????
 
It can't hurt for you to fully charge your battery with a battery charger prior to doing your diagnostics work.
 
A stuck starter will not affect the charging system.

This is true. However, he said that the battery tested at "6+" volts and the starter "wont turn". If the battery does truely have over 6 volts, the starter should turn... slowly, but it will turn.

1930 coupe has the correct troubleshooting advice.
 
Have you checked the computer???

Turn the headlights on...hit the starter....if the headlights go out its a bad starter.

Or a weak battery. A battery can show proper voltage but not stand up to a load test. The battery is the heart of the automotive electrical system, unless you know for sure that the battery is good, you will be chasing gremlins, wasting time and probably replacing parts that are good. A hydrometer is a good tool to have too and they are available at most parts houses as are load testers. Some times when the starter is used to try to start a Model A engine with a low or weak battery and the engine doesn't start the starter bendix remains engaged in the flywheel ring gear.

Put a 3 to 6 amp charger on the battery right away and leave it on for about 10 hours. It's hard on the battery to leave it discharged, and that sounds like what happened. After the battery is charged try to start the car, then run it at a fast idle and check the voltage on both sides of the cutout. The readings should be equal. If the generator side is lower, then the generator isn't working. If the generator side is higher, then the cutout must not be making good contact inside to the output side, which should read battery voltage. If the cutout seems to be bad just jump across the two terminals with a good clip lead, then read the ammeter. You can drive this way for years as long as you disconnect the jumper as soon as the engine isn't running.

Bert's sells restored original cutouts. I always use an original cutout and have never had a problem with it.
 
So, I tightened up all connections and put the battery on the charger for a couple hours and it started. That rules out the starter being bad. Ammeter still not showing a charge though. Will have to check the generator and cut-out this weekend.
 
As mentioned earlier, I put a charge on the battery and tightened up the connections and it started. Although, I'm still showing zero amps on the ammeter when driving. I checked the voltage at the battery while running and it's all over the place. That's about as far as I got this weekend (was at the Big 3 Swap Meet).

I assume the generator should be putting out a fairly steady stream of energy? Bad ammeter?
