Moedip, sory your right my idle voltage is 13.4v and at revs it gets to 13.8v.
Steve i`ll try your suggestion of the rely under the black cover of the abs unit for memory i cleaned up two under there i think ome was black the other was silver which one do you suggest.

One other thing guys, when i gave the abs some curry by locking up the wheels in the wet yesterday 4 or 5 times after doing that i did notice like a sewing machine sound comming from somewhere, it almost sounds the same as the vaccum pump under the back seat. is this normal after the abs has been thrashed a little, i could also feel it through the foot brake peddle as some very slight up and down movement, is this just the abs sorting itself back out after being hammered.
