Black and Decker Trimmer GL430: Motor slows down and stops

Fri, 07 Oct 2022 01:56:47 -0700

The motor gets hot and stops in a few seconds. The commutator has burn marks and beads of metal(?) alongside it. I have measured the resistances between each adjacent segment on the commutator, they are all between 3.5 and 4 ohm each. The brushes seem to be OK. Does the insulation break down? I tried cleaning it up but it goes bad the same way when turned on for a few seconds.

Black Decker Weed Whacker: GH900, type 2, need to remove drive gear

Mon, 01 Sep 2025 10:15:19 -0700

The roller bearing behind the small drive gear seized up and broke. I need to remove the gear in order to install a new bearing. Afraid too much heat will ruin the large plastic gear. Anyone have any suggestions or experience with this?

Black and Decker NST1024 24v Weedeater: black and decker 24v battery charger 90553447 not charging battery

Sat, 06 Jul 2019 08:08:54 -0700

I left my charger on the battery (not plugged in) in storage for a couple of months and tried to charge the battery which is dead. There is a green light that comes on when it is charging and switches off when it is finished. The light turns on for a fraction of a second when the contacts touch but will not charge.

I checked with my multimeter. I’m getting ~4VDC coming from the charger when it is connected to the battery. I also checked the board and am getting 4VDC on the input (no AC and guessing the transformer plug in the wall is converting to DC before it reaches card) and output. All the resistors seem to be fine. I did accidentally arch one of the inputs and resistor and saw the light come on. It seems to be something that isn’t telling the charger to start charging when it gets a signal back that the battery needs charging. Any ideas on what to check for that, and is it fixable?

Thanks!

Will
