Folks, thanks so far for the info, but I'm still out of business. Regarding your questions, I, along with a more adept neighbor than me, have examined at depth the charger unit and find nothing which resembles a reset button or a fuse. It definitely does not hum as normal, and the batteries in the cart still have about 1/2 charge left per the cart meter and it runs fine.
I've checked all charger and cart connections and find nothing loose or with a bad appearance???
Any further suggestions will be appreciated. Eventually, I guess I need to take the charger to a shop.
Thanks again,
Cliff
