Black and Decker st4000 CORDED electric trimmer/edger
I plugged in the trimmer and was using it for approximately 5 minutes when it stopped working. I tried plugging it into another outlet on the chance that I blew a fuse at my home. No luck. Is there an internal fuse on the trimmer I should be looking for to replace? If not, what other things might cause it to stop working?
Yes, I have the same problem. It's like the switch has a short in it. It is a 14" B and D string edger, about $60. The store replaced it for me and same problem with same model! Unsure of model (I am at work).

Have you tried flashing your generator? Sometimes the magnets in the generator loose their polarity. Google and YouTube "flashing a generator" HFLASHING the GEN
Sometimes the magnets lose their polarity. This worked on my brothers $1200 gen. Its worth a try. Good luck! Check all wires/connections first, Then try this- (Remove spark plug wire first!) To flash the field on a small home use generator, get an ext. cord & cut off the female end of it & strip the wires & connect the wires to a 12 volt car or lawn tractor battery, & plug the male end of the cord, into the 120 A.C. side of the generator.
Make SURE that the black wire which is POS/HOT on an A.C. cord, gets connected to the RED/POS. side of the auto battery, & the white wire on A.C. cord gets connected to the BLK./NEG. side of the battery. If the ext. cord wires are not black & white, then the smaller prong of the plug is the POS./HOT
Plug the other end of the ext. cord into the generators 120 volt side (**remove spark plug wire**) & pull the starter cord 4-5 times, then remove the ext. cord, reconnect the spark plug wire, start the unit & plug something of 120 A.C. volts in to see if it works. Then let it run for about a half hour with 2 - 150 watt lights to help re-generate the unit.

If it stops after 5 minutes whether under load or not, and assuming the air filter, plugs, and fuel filter are new and or clean. The fuel pump is suspect. If it is in a motorhome try conencting it to an external fuel source that is at the same height as the generator. Then higher than the generator. If the problem persisits replace the fuel pump. Or just check fuel pump pressure with a gauge. BE CAREFUL do not use an automotive fuel pump Onan have special low pressure pumps, so use OEM part
You have to get a cord that has a plug on on it. On the other end of the cord strip the insulation off the ends of the wire about an inch. It would be easier if you put small clamps on the stripped ends of the wire. Connect the black wire to plus on a car battery and white to negative. Start the generator and plug the cord in to a outlet on the generator just for a second and take the plug out. The generator should now be producing electrical current. If not there is something burned out internally.
I have a 5 year old EU300is that would not start with or without the battery. I went through all the usual such as gas, plug, oil, etc. The battery showed 12 volts, however, when tested further it would not hold a load. I bought a new American made battery and now the unit runs fine.
Sounds like you need to remagnitize your alternator, you can do this yourself but do it like this.
FIRST AND FORMOST STOP THE ENGINE AND WAIT TILL IT MAKES A COMPLETE STOP! AND LOCK OUT THE ENGINE SO IT WILL NOT ACCIDENTALLY START.
pull the spakplug wire off the engine this WILL HELP ENSURE IT WILL NOT START. next take an old 120v power cord and cut the plug off with atleast 8 inches of wire on it. if it is a 2 prong wire or 3 it doesnt matter. grab your self 2 nine volt alkaline batteries, try just one battery first by plugging in the cord into a 120 volt receptical on your generator and make sure the circuit breaker is in the on position. MAKE DAM SURE THE GENERATOR IS NOT RUNNING BEFORE YOU DO THIS OTHERWISE YOU COULD BE ELECTROCUTED. it is quite safe as long as the generator is NOT RUNNING. put one lead on one terminal of the nine volt and the other lead on the other terminal and you will see a small spark if done right.MAKE SURE YOUR NOT DOWNWIND OF GASOLINE FUMES! if you have a 3 wire cord do not use the green ground lead use only the black and white or blue and brown. if its a two wire cord you cannot get it wrong. tap the wires on the battery terminals a few times. this shoud have remagnitised your rotor and stator. remove the cord from generator completely and put it away from kids and the incredibly stupid for safety. restart generator and plug in an appliance to see if it is making electricity. I recommend using a true rms digital voltmeter to check the voltage it should be between 110 and 130 vac rms for non regulated generator sets. if the 9 vold didnt do it you can use 2 nine volt batteries in series to flash the field. SAFETY FIRST ! ELECTRICITY CAN KILL, YOU DO THIS AT YOUR OWN RISK, I AM NOT LIABLE FOR ANYONES STUPIDIY. IF YOU ARE UNSURE HOW TO DO THIS THEN DO NOT DO IT! TAKE IT TO A QUALIFIED REPAIRMAN. LIFE IS IRREPLACIBLE SPEND A FEW BUCKS TO FIX.
Hi Steve, Sorry to take so long to respond, I didn't get the email telling me to look here. Because you're in a dire situation I'll give the quick and dirty but very dangerous way to flash any generator. You're gonna want a friend to at least watch and shut the generator off if you get into trouble.
Make a pigtail from an unused 110v electrical cord, pretty much any cord will do but you want one that is easy to hang on to. You want about 1/2 inch or maybe less of bare wire at the ends of the white and black leads of the cord. Plug this into any of the power outlets on the generator.
Start the generator and let it come up to speed.
Using a 9v dry cell or a 6v lantern battery, tap the bare wires of the pigtail onto the battery terminals. Polarity won't matter. You want ot be very careful doing this because if it works you'll suddenly be hanging on to a 110vac live wire. You only need a very short burst of electricity into the power windings to get the rotors magnetic field going.
Once you've done the slap above remove the pigtail and plug in a light or some other small load for 5 minutes or so. We just want to make the rotor coil work for a bit to "recharge" the residual magnetism in the rotor.
Please be very, very careful - in the shop we only do this if there is no other way to get it done, and we work as a team with the spotter having his/her hand on the engine kill switch.
