In Reply to: 4010 fuel gauge - update posted by 4010rlw on March 26, 2007 at 12:55:53:
Sorry, your terminology is incorrect. There never was a 24 volt positive grounded 4010. The 24 volt system consisted of TWO 12 volt systems with a common ground, one positive ground, the other negative ground. That way the 24 volt generator charged two 12 volt batteries and one 24 volt starter loaded those two batteries, while 12 volt loads were split between the positive and negative 12 volt systems. The fuel gauge was supplied from the 12 volt system with positive ground, just like the gas tractor that was 12 volt positive ground. Its most likely that there were several vendors of gauges and senders (which always have to match) and some gauges (though none of the senders) appear to have been polarity sensitive. I know that the indication changed when I swapped my gas 4020 from positive to negative ground, but it only disappeared because the wiper of the sender was worn away. When I corrected that and adjusted the float arm, it again gives reliable fuel level indications with no other changes. Between vibration and age, its no surprise that the sender has worn out.

If it would just start when I turn the key, then I would use it more often. In addition to a bad case of old age, most of the tractor's original electrical system was simply too unreliable to keep. The main focus of this page is to show how I upgr
