[Handbrake affecting electrics and power loss]

Hello here is my fault on my defender 2005 model, when I release the handbrake the engine light comes on and a few more lights on the dashboard, the fuel and heater needles flicker up and down and I loose power so a hill start this can be a challenge

I have disconnected the light switch cable on the handbrake but this has no bearing as it still has the fault - it's not there all the time but most of it.

Are there any other electrical things onthe handbrake that I could look at?

Any help would be greatly appreciated.

Best regards phince
