Hi All,

Not sure if this is in the right section,

I've got a 3040 Chinese machine that blew a fuse the other day.

Stopped the machine straight away.

I didn't have any more fuses so had to go buy some.

Put the new one in but now whenever I turn on the unit power it turns on the spindle and I have no control over the RPM.

Same issue as this Video but couldn't find any links for it.

Any help would be great

Thanks
