Kubota AV6500B portable generator

[BlownL67]

Last week I won an auction for an AV6500B generator on Ebay. It was listed from a pretty repuatable seller in running condition but was not putting out any power.

The unit was shipped to my friend since I am deployed to the Middle East and he got it up and running and wants to solve the power output issue. I have searched high and low for manuals and cannot seem to come across any either!

Can anyone give me a good place to start when troubleshooting the no power output issue ?

Thanks! - Mark

AVR, which is the auto voltage regulator. Many seem to fail there for one reason or another. Dunno how to troubleshoot without manuals tho.

See if you can find out if it failed to charge after standing for a long time,if so,


If its anything like my lowboy gl6500 it may require flashing to re magnetise the exciter system.
There is nowhere in my WSM that mentions this so it may not be recommended. I have been doing it on various gennys for years but try at your own risk:
Connect loom size covered wires with 1/2 stripped back on a jumper battery +ve and -ve,start genny,switch voltage selector to 110,quickly shove the free ends of the two wires from the battery into each of the 110 v recepticles two smaller holes(not the larger earth one)...if luck is with you, it should start to charge again after hearing some electrical arcing from the ends of the wires.
