I think i just saw OU at last !

First : 300 W squere wave inverter is ok, all i had to do was to remove
ampermeter between inverter and battery, but now i can not
see amperage values on the input side and THAT IS why i
said : OU at last with ? , not with ! at the end of the sentence...

Second : After i succeeded to use inverter i run the motor and i ve
monitored the voltage of the battery, it was climbing up,
not descending...So it could be OU at last...

Third : Since i need one more person to shot the film because i need
both hands to hold the motor i am going to shot another video
later today...

Later !
