Hi All, I'm currently having issues with the ECU-B fuse on my 105 series cruiser. I replace the fuse and turn ignition to ACC and all seems ok but when you start the engine the fuse blows, digital clock goes out, central locking plays up etc. I have been trying to chase out the fault but with limited knowledge I'm not getting very far 
, also sometimes when the fuse is replace you start the car drive for a while switch off and start again the fuse blows.
Would anyone have an idea where to start. all help muchly appreciated
