Bosch ATCO 2000 garden shredder. New switch fitted, this keeps blowing the ?
 
                Had a switch fail to stay on unless pressed manually, for a BOSCH ATCO 2000 garden shredder. Ordered a replacement switch and followed the wiring 7 replaced to that of the original switch. Now the plug fuse keeps blowing, the switch operates the machine for a few seconds. 
Any help here please, if possible.
Thanks.
