the starter turns . its as if the batt is dead, but it still reads 12.6 volts when off, it trys to start then just clicks as if its dead, strange, put jump leads on it and it takes a bit to start to get power to it, also noticed once trying to start the boot lock clicks? and when its running, if you rev it the lights go brighter,

That last bit sounds like maybe a voltage regulator?? Make sure all earths are good, new battery or known working well one, and known working alternator

the batt is a good known one that was in a diesel , the alt must be working properly as i didnt get 14.4 volts before we changed it, now i am, and earths were fine, i noticed , i put the volt meter on the batt and asked him to crank, it went from 12.6 down to 2-3volts within seconds,

Sounds like an earth problem.
Check all the wires, it's hard to say with it being a conversion, could be some duff wiring there somewhere.
