Broken EMC-1000 charger

Postby samush » Fri May 19, 2017 10:47 pm

The charger that I'm using broke after charging my 20ah pack 17 times, and most of those were partial charges! :cry:
When I plug it in the lights don't come on. Does anyone know how you can fix these chargers?

If no lights, noise or sign of life, you need to open it and see if there is a blown fuse or other obvious sign of smoke release.

If it's new, it may still be under warranty.

I took it apart and it looks okay, I cant find any fuses or anything burnt. I bought it 2 years ago and only started using it this year.

Can you post a picture of the board? I'm not familiar with that model, but from a picture I might be able to pick out parts to check.

The item circled in red is likely to be the "fuse". These are power resistors with an integrated thermal fuse that will blow if it gets too hot.
Look at the markings on the part and try measuring the resistance of it.

OK, glad you found the fuse. If the new fuse blow immediately, you have a bigger problem.
