After crank starting all summer, I finally got myself a battery
. My cub is a 1950, positive ground, 6v system. I installed the battery and gave the starter a try. Success! The starter motor works fine and the cub fired right up. I then decided to see if the lights worked, so I flipped the switch to "D" and "B" and nothing
. I then started wiggling the wires that go into the switch and suddenly the lights came on. Im going to have to pull the hood to check for a loose or coroded connection, but at least i have lights.
So finally, I decided to check if the cub was charging. Here is what I found: With the lights on, the ammeter reads about half way on the negative side. With the lights off and the battery disconnected the ammeter reads about negative 2. With the cub running and the switch on "H" the ammeter reads exactly zero. When i put my multimeter on the battery with the cub off it reads exactly 6.2 volts. If I put my multimeter on the battery with cub cub running and the switch in the "H" position, it reads 6.4 volts.
It seems that the generator is charging, but at a very low rate (.2 volts). I dont think that voltage would ever be enough to re-plenish the battery? Any suggestions what I should do next? I have not polarized the generator as of yet, but im not sure if that would help anyway since the current seems to be flowing correctly.
