i am having another go at the five link upgrade to my Mk1 escort.went to the shed to start again after the christmas break but couldnt get the (newish) mig to run.its outputing a feeble spark like if you dragged a light earth cable across the positive on a battery.
i checked the following with no sucess,anyother areas before i drop it back to halfrauds.no wanting to do this as they will only send away and ill be without for weeks at least.

earth clamp attached fine
metal bared,ground it back
plus/neg connections at mach tight
shroud/tip removed and refitted
wire running through fine
different power settings checked
cover removed and nothing obvious
continuity checked on gun/cable feed wire


any ideas

cheers
