Before you start removing covers and panels unplug the mower. Turn the mower over and carefully try to spin the blade by hand. Your checking to where the issue is most likely to be. Does the motor sound different when you pull the Start trigger? If it sounds a lot faster than normal, it could be an issue between the motor and gearbox. Does the blade spin really easily and feel like it's not bolted down? Does the blade not turn at all like it's 'locked' or 'jammed'? - A loose or floppy blade is commonly the centre mount bolt for the blade is loose or the blade isn't seated correctly. - A 'locked' blade could be a gearbox or a motor issue.

It has failed or failing cells. The pack is full of 18650 batteries. Sometimes you can regenerate them by removing them and charging one at a time. Or the electric motor and bearings need lubrication. See if the blade spins easily by hand.

Make sure the battery is fully charged

Question edited for full 'make model (what it is)'. Nothing makes me think it has an internal fuse. https://www.jackssmallengines.com/jacks-parts-lookup/manufacturer/black-decker/grass-trimmer/gh900-type-2/grass-trimmer and also https://www.google.com/search?q=gh900+trimmer+replace+fuse ..

The fifth picture from the top at https://www.homedepot.com/p/BLACK-DECKER-12-Volt-NiCd-Battery-Pack-1-5Ah-HPB12/202504240 indicates the positive terminal is the left hand one, as you face the side of the battery that slides into the tool. Thus it's on the right as you hold the spring latch on the other side of the battery. I hope this helps. Cindy Wells

if batteries are tested good check and test switch

This unit has 3 separate 12v SLA batteries, yes(?).

Remove or disconnect the batteries and try charging each battery separately with a 12v automobile battery charger.

I suspect one or more of the batteries has not taken a sufficient charge and is "fooling" the charger that came with the mower.

Once you have separately charged all three batteries, reinstall and try.

Pressure switch is stuck closed.

Good for you

When checking for a spark you must make sure the spark plug is well earthed against the cylinder, and give the starter a good pull, if there is no spark try a new clean plug ( make sure the ignition switch is on ) if all this fails then unfortunately you may well need to fit a new ignition coil, this will be situated under the covers against the flywheel.

Switch may be shot. If it was stored in a damp spot that could do it.

The first thing to try is the Black & Decker website. Second use Bing, duckduckgo, Google, Etc
