switch box or trigger on 115 Merc

[fishingdeal007]

Hey guys Im working on a 115 Merc 78 model and no spark. I got to checking and I got 12 volts going to the pack on the red terminal, I got 12 volts on the bottom terminal when the switch is in the on position but nothing on top on the wire going back to the coil with the key on or in the cranking position. Trigger maybe. Thanks

You need to get a manual and do a full resistance check on the stator and trigger before throwing parts at it.
