Is it possible to rewind/rewire or reconfigure a Cart charger to be used in a 24v or 12v application ?
I am thinking that some rectifier coil something or other can be modified to change the output....just not by me.
any electrical guru out there with a plan ?
Thanks.
Go to "http://www.buggiesgonewild.com/". Its a huge golf cart forum and they will be able to answer you question.
If it's one of the really old ferroresonant style chargers...and you're kinda crazy like me... you can find the secondary winding and either cut, tap into, or otherwise dig into it and find the perfect spot on the winding that is of a lower voltage, make sure it's the correct voltage for your wishful needs (measure the unmodified output AC voltage at the transformer's windings at no load and do the math), and reconnect the bridge rectifier to that point instead of the normal end of the secondary.
I made a nifty 18 volt charger out of an old 36 volt 20 amp one this way and it worked fine. Years later I changed it again, this time to a 6 volt charger which I still have working today.
But this only works if it's an old one without electronics, and you can actually get to the windings... you may have to unwind some or peel them up to get to the correct spot. It kinda wrecks the ability to go back...
Not really a good technique for folks that don't understand what they're doing, but if you do, it works. The current rating of the modified charger will be the same; the wattage it draws will go down accordingly
