seem to have solved it
charge the battery over night, took a part of my 180 positive batter terminal the red plug, and seem to have fix it, but the one off the 32 looks visualy ok, so will have to clean the connection and retry it, as for the brake issue, it had alot of air in the lines, so i bled the brakes and all seems ok, no dramatic rev drop, and perfect starting up.
just a matter of stupid little stuff,
thanks to all for the input
