20 Most Recent Vector Power Inverter - 3000 Watt Questions & Answers

Yes it would possibly cause these symptoms. I would imagine these were cut, to isolate the fault? However IF NOT, then I cannot understand How or Why, these Rectifiers would be cut?

Above are your manuals.
You will have to use these manuals to troubleshoot and hopefully repair your unit.
Inverters are very difficult to repair due to the enormous input currents involved, and one must be 100% sure it is OK, before powering up, as explosion,or fire, are a very real possibility, if anything is wrong. Practically, one should get this unit repaired by a "Qualified" expert. Personally, I would contact a Vector, local or head office, and ask for a referral to an authorised Service Center, when in contact with them ask for a "Quote" before proceeding with any repairs.

Check that ground is correctly connected. If nuetral is provided, ensure it too is connected. Your total load is 780 watts. Check power in and ground out of the supply side. There may be a fuse in the inverter on the output side also, replace if necessary. If fault light does not go out after these checks, you will need to contact Black and Decker who manufactures the vector series now.

Fuse is there, but more damage is suspected. Transistors damage easily and capacitors will short when subjected to reverse polarity.

If the unit doesn't have an external fuse and it doesn't reset itself after an overload, it possibly has an internal (onboard) fuse that needs replaced. Possibly de-soldered and re-soldered...

The cost to ship lead-acid batteries is really cost-prohibitive. I suggest going to your local Batteries-Plus store for the replacement.

Without a schematic diagram, and troubleshooting procedures, it is very very hard to service such a piece of equipment such as this. I get a few of these over a year and invariably, it is the Output Devices, that fail, and along with this usually the CPU,or "Brain" gets "Fried" as well.
You have to treat this in two parts, the Input and the Output, the only way to repair is to isolate these two sections, then troubleshoot and repair the Input section, FIRST, once this is all going correctly, then, the Output section, is attended to if applicable, often it is an "Overload" on the Output side that causes a failure on the Input side, so many many times we have two "Faults" that need to be attended to, if only one is repaired the unit will soon fail again.
One simply MUST obtain a service manual, to be able to have any chance at a repair. The best way to do this is to contact the manufacturer, and ask for one. Then you will have a schematic diagram, to work from.

yes if this is close to mine there is a cover over 2 feuses on the back

Had a seller on E-Bay respond with a Vector service # where I found a local dealer through and ordered the part.

It appears to be something to do with this https://www.google.com/search?q=keb+12f5+that+shows+E.EF+external+fault 7.13.1.6 External fault With Pn.04 "Ext. fault input selection", one or more digital inputs can be programmed which can trigger the error "31: ERROR!

I have a quiet cool roof top air conditioner and am looking for parts for it.
