EZGO Textron Golf Cart Charger Fuses

Darn, my tinfoil hat is shrinking again.

You're going to bend over your batteries with that hat on one day and shrink something else!

I put the two new fuses in the charger, plugged it in, said a little prayer and turned it on... and IT WORKS!!! Thanks for all the help and information!

BTW... I'm pretty sure it doesn't matter, but I put the KTK-40 fuse closest to the outer edge and the FNM-40 fuse closest to the internals of the charger.

I know they're expensive, but I would put 30A fuses in it. You may have just have had a bad fuse. I've had those get damp and the aluminum strip inside dissolves until the fuse blows. You can also try at your hardware store for those fuses. They were also used in AC units! May be a lot cheaper that the cart shop!

By the way, I'm glad it works!

Definitely check your local stores. 30A Slo-Blo Midget Cartridge fuses only cost about 3-8 dollars.

So Johnnie, this charger shown I understand will not turn on automatic but will it cut off automatic or will it charge until the timer runs out? I just got one of these same chargers with an older Melex cart but haven't tried it yet.

Thanks for the additional pictures showing what's on the other side of the transformer.
Now I know exactly how it works.

ON/OFF is controlled by the timer alone. Battery voltage plays no role in turning it on or off, so if you connected it to a watermelon, it would try to charge it.
Not saying that you would, but if somebody somehow connected it to a car battery, they would get an acid bath when the 12V battery exploded.

That's probably one of the main reasons later versions of 36V chargers sensed battery voltage to turn on. (Wonder how many lawsuits that change took)

The Transformer and Capacitor arrangement used, does "automatically" regulate the output current to the battery, so the term "Automatic Charger" on the faceplate isn't actually incorrect, but the term took on a new meaning when later chargers sensed battery voltage to turn on and off, so now it is a misnomer.

Thank RIB,
Sorry, missed what Johnnie said thanks for red letters. must have not had my glasses on. Still learning on these carts, it sure isn't a 56 pickup which I'm used to restoring.
