I have been reading the manual and forum for 3 days with no success. When I run the THC test can hear the control relays click with no fire. Short p&p cable plugged into the DIV input. Long cable plugged into the torch on off in the control. the DIV out on the VIM is connected to the THC black and red wires. Software runs THC shows up in the firecontrol program. I am sure it’s something simple but my chemo brain is stumped . I have 3 extra cables that are used for non p&p divided signal output.
