from the mariner 70 manual:
Test procedures and specifications are provided for
checking primary ignition voltage while the engine
is running and/or being “cranked.”
coil input (primary) voltage meter test range is 400volts DC, for a reading of 150-250Volts at cranking, 180-280 volts at 1000-4000RPM.
multimeters that handle 400VDC are cheap and plentiful in the UK - £35 will get you a Vichy VC99 clone).
You can check the stator coils with just an ohmmeter (resistance).
