Testing ignition trigger on 1969 merc 1250 " FrankenMerc " trigger part # 393-2918A6
Does anyone know how to test these old ignition triggers. I took it to my Mercury dealer and he said he hadn't tested one in decades and he didn't remember how to test it. I thought he might be able to test it on his old Mercotronic analyzer. I followed EMckelvy's procedure for testing my switchbox and coil and both appear to be working fine. I then pulled the distributor and disassembled it and want to test the trigger. It has 3 leads one white, one brown, and one black. It appears that I have a Merc 1350 (1971) powerhead serial # 3116535 on a Merc 1000 labeled leg with a Merc 1250 Cowl wrap. The ignition appears to be from an earlier Merc (950, 1000, 1100.1250) as it is the merc distributor # 393-2799A9 . It has the merc trigger # 393-2918A6 The rotor appears to be from a merc 950 or 1100 part # 393-2921 Any help as to how to test this old trigger would be greatly appreciated!!! Thanks in advance.
