You will see a much higher voltage with out the battery load.

typical..

you get caught on a technical detail and you resort to eithr changing the subject or trying to deflect.

Also.. an 11a 6v generator should be rated for 80w minimum.. the later ones should do 150 to 180.

remember.. charve voltage on a 6v cell is 7.2v

voltage doesn't burn wire.. the only thing voltage will play a roll in is figuring wattage dissipation when viewed with amperage int he circuit, and what type of insulation you need on the wires and windings.

Lets stick to some real electrical principles here and not 1930's era scare tactics and myth-understandings.

loose connections aren't my concern.. that's a maintenance issue. if someone doesn't maintain their machine. thet's their problem to deal with.

If you leave a bit more of the original cut out base, then it will look virtually stock, like this:

Humph I may go dig in the trash can and change it looks better should only take a half hour or so.

You spelling looks like you have drained a 6 pack.11x6 is still 66 not 80.

Where did the 6 come from ?

11 x 7.2 = 79.2 so an 80 watt rating would be correct ? no ?

I am not an electrical guru but I can comprehend simple English .

Generator is not putting out 7.2 v full time.What happens to the wattage when the generator puts out 8 v which it will have to do when the .7 drop of the diode is figured in.How high will the voltage go on a cold battery.The 9n tractor has the same charging system as the Model T Ford, Model A Ford and Ford cars and trucks until late 1938.I have owned a Model A, 3 36 Fords and 1 38 Ford with 3 brush generators.I know that loose conections or poor grounds can burn out light bulbs and generators.I know that a 3 brush generator can run over 20 volts when Dufus pulls the battery cable off to see if the generator is charging.I was taught to read the ammeter.

Ford rates 11 amp car generators at 119 watts.I expect because they have cooling fans and run at a higher speed.Ohms law gets tripped up at times.

How about posting some voltage readings with the generator charging.Voltage at generator armature, voltage at diode out put, voltage at battery.
