Hi

And replace by a new engine and the fault persists
I already tried without heads and follows the failure

Someone who can help me find fault

You means When color change , it makes grind sound and no change ?

If yes , You need replace the power board.

I had a same problem on single head.

check on e-bay . search "circuit board repair"

It could be the power board but it is probably the joint board. I have a B series 4 head doing this right now. It has a bad transistor on the board. Good luck finding a joint board for a A Series. The revised board SWF now has doesn't have the right connectors and correct number of plug ins.
