    1996 Johnson 40hp No Spark

    dva adapters are just AC rectifiers using diodes and then they store the voltage peaks in a capacitor for meauring in DC mode you can make your own dirt cheap for such infrequent use. https://wrcoutboards.org/wp-content/uploads/2020/03/DVA_CHEAPO_SMALL.jpg

    Evinrude 25202r no spark

    your plug wire (being metal) is likely still good unless it is cracked and/or ... broken in a bend somewhere . Usually the poor connection is at either tip connnection point and snipping 1/4 to 3/8 will restore some good non-oxydized surfaces for the coil's HV pin and you can remove...

    Evinrude 25202r no spark

    both short primaries wires will give you 1 or less ohms either one measured with the HV pin should give you near identical readings ( 3-8 kohms approx.) see TEST NEW COILS section.....in this link to servicing similar magneto on a 3hp...

    Evinrude 25202r no spark

    see pics where you "screw in" the HV plug wire and info from the JOhnson service manual on oldies from late 40s to late 60'S .... same old magnetos like your's

    Evinrude 25202r no spark

    the hv connection is the point of connection of the plug wire into the coil. today's coils have a screw pin where the 7mm plug wire is actually screwed on the pin. old coils had simple needle like pins. it is very important no to use automotive CARBON fiber wires..... use only solid...

    Evinrude 25202r no spark

    IMHO... this is a standard magneto and both coils should show a reading from plug boot to coil secondary to ground.... somewhere from 3-8 kohms depending on manufacturer. could bad coil, bad HV connection (corroded) bad pin prick in the boot open plug wire due to flexing etc...

    it measures the coil resitance, plug wire and plug booth pin contact for proper continity.

    when Telco's ran central offices on gazillion relays.... lapping (burnishing) relay contacts was the usual remedy.

    Evinrude 25202r no spark

    post the resistance values as measured from plug boots to engine frame . look for a steady ohms value 3-8 kohms approx while moving the throttle from idle to high speed .

    9.5 issues

    links and carb adjusted ? is this a new problem or ... .a new motor to you ?? did it ever run good does it run ok at higher speeds above the ildle tried adjusting the side knob to up the idle rpms ??? have you adjusted the timing ??? what ohms value do you see between boots and...

    the orifice plug is just a hole" if you cleaned them they should be OK ... be focus on other stuff for now .

    ELECTRICAL CONNECTOR TOOLS

    Most of those amp connector pins have small locking tabs. the idea is to insert a tool to overlap the locking pins ...sometimes one pin sometimes 2 pins! I have managed to extract some by flattening different size finishing nail by hammering them out on an anvil and grinding the...

    1995 Johnson 130 No Power Under Load

    The carbs have been checked and cleaned.... ....it gets up around 2k rpm and fell flat on its face unless someone was priming the ball on the fuel line don't mean to be picky but exactly was done on the carbs. were all orifices cleaned and air blasted. the HS orifice plugs...

    Battery sparking

    no offfense but.... I had a 9.5 hp as my side kicker for trolling... trolling which does not have to be at the other end of the lake all the time . I ran a 3 gal tank on the 9.5 ahd found that even trolling during several days was adding up at today'S 7-8$ Cdn per gallon (gas here today...
