Daytona woes...dash flicking on and off when clutch pressed

Right, a tad lost on this one.
Basically the dash acts up like it does when you first turn key to on position whilst driving. Usually when clutch held in coming to a stop. It goes back to normal and then the speedo stops. Been happening for a few days now. And I had a dead battery yesterday. Changed it thinking it's years old and that would fix it but no. Any thoughts? I'm guessing barrel or dash wiring or bad earth.
Cheers all and happy new year!

 

Potentially yes.....had a fiddle with the clutch quickly to see. Nothing obvious but it hasn't done it in four days.
Will leave for now and if it happens again I'll take it apart and look further.
Cheers

 

Soo..... Not a loose wire methinks. Started acting up this morning on the way to work. Same on way home. Stopped at garage for supplies and battery dead. Bumped her and got her home.
I'm thinking stator?
If so, is it an easy job, I.e remove left hand cover after disconnecting battery and stator plug from harness. Then remove stator from cover, replace and re-fit?
Won't be the rotor to replace too? Not got the tools for that.
All help gratefully received.
Feels like I'm cheating on doris riding Kylie to work.

 

Think I know what's happened here......

 

Yeah. The plug is a little melted. Other end much better. Haven't ordered rectifier yet. Will do tho amd change soon as. Tbh it's ran many times whilst failing and it took till new battery was flat to investigate properly. My bad, but just done 90 days straight, no day off. More pissed off you gotta drop coolant to just to get to one feckin bolt!
Fingers crossed........

Cheers.
