Overloaded inverter will not power up


Have you checked the voltage going to the inverter? Sounds like you may have exceeded the load that he inverter can handle but not enough information to confirm that from this end. You mention "plugged into my van battery", possibly you have this plugged into your Cigar Lighter? Mega fuses are usually really high amperage fuses, much more than the inverter could blow and save the inverter. The fuse should be matched to the load and about 50% higher. If the device is rated at 10 amps, a 15 amp fuse will provide protection where a mega with 500 amps will act like no fuse at all to the inverter.

I don't have a manual for my small Black & Decker Smart Charger. I'm trying to charge the battery on my '07 Honda Rebel 250cc. It has settings for 2/6/12 volt batteries. How do I hook it...


Hi,

You just need to set black & decker charger to 12V . Don't make mistake while connecting + / - leads. + lead usually come with Red color cable. You can use the AVO tester to justify the lead cable. The charging time is normally about 10 -12 hours (or just just check the status on your charger display). If your charger does not has trickle charge facility, you have to disconnect your charger after 12 hours continuous use.

Also, you can find the guidance about your charger here :

I have a powerware 9120 (6kva) and about 1 week i replaced all 20 batteries after the UPS failed. but its displaying battery disconnected when i try to power it. i cant seem to figure the problem. i tried...


Did your UPS display "Battery disconnected" or did it display "Battery Failure"? If it was "Battery Failure", for some reason the Powerware 9120 will take almost 18 hours after plugging in to power after battery replacement to correct the Battery Failure indication. Charger has to charge up the batteries, followed by an automatic battery test by the UPS. If the indication was "Battery Disconnected", you will need to check the internal fuses to see if they are blown. If the UPS keeps blowing fuses, it will require a board repair.

I have not used my go.go elite traveller plus for several months now,and when i went to switch it on the battery light would not come on.I have tried charging the battery and the power light illuminates...


Ann You probably have a problem with the charger and your batteries. If it has sat for several months and wasn't charged during that time the batteries are too low to be charged and the charger cannot pickup the charge on the batteries. Now check the charger to see if it has a fuse if it does check the fuse to make sure it is good If the fuse is ok then if Charlie has a voltmeter he cqn check the output of the charger at the 3 prong plug set the meter to 200 volts dc and touch the 2 outter pins of the plug careful not to touch the barrel of the plug. the voltage should be 27+ volts output. If you aren't getting any reading then the charger needs to be replaced. Hope this helps

No signs of electrical power. The vertical orange light is off.


try plugging into a seperate wall socket if no joy the charger may need peplacing i would suggest ebay. but try the socket first.
if it isn't powered by a charger and plugs directly into the mains try the fuse in the plug.

Check the FUSE usually located in the plug if so equipped try owners manual. Also check car fuse for short or overload fuse opens, also bad battery replace it, try Mouser electronics lotta techs are ordering on line no min order.

Ezip 150 electric scooter. won't start.


Hi, did you charge the batteries for at least 8 hours? Make sure that your charger has a RED Light When you plug it in, You should see Green light in 4-8 hours depending on the Batteries.
Secondly Your scooter batteries were dead when you got the Scooter, Judging from the fact you didn't get a Charger with it. I would recommend getting a voltmeter and checking the battery voltages. If the voltage is 11-12 volts, then you need new batteries. If this doesn't work check that fuse on the scooter it could be blown.
