No current flow in load

I used IRF840 MOSFET and i have three different grounds (300 V, 15 V, 5 V) in my circuit. Everything working fine, the MOSFET received gate signal correctly but when i connect a load coil there is no current flow in that. Tell me why this is happening

You need to show a circuit diagram.

Three grounds at different, non-zero voltage is a misuse if the term. Ground is 0V by definition.

I suspect you have three power sources with different grounds, all of which are normally connected together. That is, if you want things to work.
