If it is humming ONLY when you connect it for charging and does not hum when you have no load on it...it has too much initial load and the humming is caused by an output current overload.
I don't know what you are trying to charge....if you are VERY careful and you can monitor the output current load....you may be able to get a charge....BUT BE VERY CAREFUL!

How do you charge the unite . I have charge for more then 24 he's.

How old is the battery? Batteries do ware out. Have you had it tested? You can get it tested at most Sears Auto stores for free. If you can take it out of the vehicle and take it to Sears, then you could save yourself some time and money. I am assuming that your battery charger is working correctly. Do you have it hooked up to the right terminals? When the unit is plugged in, does it make a low level humming noise (indicating that it is working)? Does a value register on the gauge?

24v sds.no lights on charger but making humming sound.all 3 batteries not charging.any ideas?

If it is out of warranty open it up and check the fuse inside. This has happened to me several times with several brands, and it has always been the fuse. They are usually replaceable at Radio Shack or the Auto Parts Store.

Hope this helps!

Battery Will Not Charge

Hi amber_penn, battery charging problems usually come from two sources, the battery or the battery charger.

Check the contacts on both the battery and the charger for oxidation, dirt, etc. Try cleaning the contacts with a little alcohol on a swab. The charger seemed to still work judging from the humming sound. Next step would be to buy a new battery.
