2nd trigger zero crossing help
 

Hi guys,
just finished modding my 2nd trigger to zero crossing mode by grounding pin 14. When I put the multimeter on both 5v and ground with the lm chip removed I get 0.8K ohm resistance is that right? Or do I have a leak somewhere?

Just want to check before I blow something up.

Thanks
Jono

Are you measuring in circuit? As in, is the 2nd trigger circuit installed on the Megasquirt board? If so, you are measuring across the entire Megasquirt circuit...

Yeah i'm measuring the whole circuit. I just measured from the 5V and Gnd points on proto area. Whoops I can see my silly mistake.
Cheers and hope the circuit works!
