Before I buy a new battery......

Postby JIMINBUFFALO » Fri May 29, 2015 11:04 am

Been having issues with my 1950 6V Cub. Started up great in the beginning of the spring but seemed like the battery got low. I filled up with distilled water and charge it but still no results.

I took the starter off and bench tested it and it spun well. I then moved to the solenoid which seemed sloppy. Put the new one on yesterday but the same results. The starter spins but it seems like the battery is still low even though I checked it with my multimeter and it is showing over 6.13 V. How high does it have to show in order to turn the starter?

I checked the other connections. Main battery terminals are good. I checked with the multimeter at the solenoid and it is showing the same voltage as the battery terminal test results.

I pulled out my receipt from Tractor Supply for the current battery and it shows that it is four years old. A new one will cost $80. Also, the previous owner eliminated the connection on the crank so I cannot turn it over using the crank.

Do I need a new battery or what is next to check?

Thanks for your help. -Jim

Take the battery to the auto parts store and have it checked.

The battery's 6.13 volts does not mean that it's capable of producing enough amperage to crank over the starter and engine.
I have an excuse. CRS.

I suggest taking the battery to a auto parts store and let them check it, they can load test it which simulates the load that the tractor starter would put on it. As Eugene stated a static tes with a metered does not show the true capacity of a battery to start an engine.

I started out with nothing and now I only have half of that left !

Do you have a battery maintainer? IF not you may want to get one. Also check you connections making sure that they are tight and clean. Clean is the key word here.

Solenoid? 6 volt? Does your tractor use a pull rod to actuate the starter? Just above the clutch pedal with a loop for finger pull?

What does the voltage read when you engage the starter?check it right at the battery posts, and if it is good there start moving down the line toward the starter. If you still have the original wiring, ground to side of battery box, that may be the problem, If the bottom of the battery box rusts it gets a weak connection and does not crank well
If you are not part of the solution,
you are part of the problem!!!
