Yes if the points are closed.

Re: new battery goin dead
Sure, the points being closed will short the battery to ground and kill it.

In any event, if you have a mystery battery drain like that and it isn't obvious, I'd recommend taking off the negative battery cable and put an ohmmeter between the disconnected negative cable and ground. It should read infinity, or very high, or open. If you get something less than 1,000 ohms, start looking for frayed wires, accessories left on, something. (That's for a positive ground system which is original) If the battery fails and you have over 1,000 ohms, you have a bad battery. Last edited by Mister Moose; 11-18-2020 at 03:06 PM.

Re: new battery goin dead
Mine had a low current draw, a cutoff switch solved the problem.

Re: new battery goin dead
Charge the battery and disconnect it then see if it discharges. It might not be the fault of the A

On another note, draining a battery repeatedly will destroy it. Until the issue is figured out you should remove a battery cable when you park. Also put a trickle charger on the battery for at least a day or two after draining it.

Regardless I believe he has his answer, leaving the key on will drain the battery. As he said in the first post

Re: new battery goin dead
To check for the battery draw, it really makes no difference whether the test light is connected between the positive or negative leads. It'll still light the light if the draw is there.
And if the points are closed there will be a draw and the coil will get hot. |

Re: new battery goin dead
As a matter of safety I always just pulled the NEG cable off after I shut the Model A down after a drive. And if I was going to let it sit more than a month or so I'd hook up a trickle charger until it was charged and then unhook that.

Re: new battery goin dead
I have found 6V batteries have a shorter life compared with 12V.
Now my 6V has died I have made the decision to convert. I believe it is important to change the starter at the same time otherwise the impact on engagement is far too severe and sooner or later something has to fail.

Re: new battery goin dead
this is a build in progress . the only wires are what is needed to run engine and charge battery. the ampmeter shows a 10amp charge when it runs . battery voltage read 2.75 volts this morning and it has been on a charger since that reading was taken.
