9.9 mariner no spark

[BLM762]

I picked up a 89 mariner 9.9 cheapish knowing it had no spark I unhooked the kill switch still no spark either cylinder
I think the trigger is good I get an ohm reading on it but the stater I get a reading from the black/yellow to ground but no reading from black/white to ground or the two together just trying to figure out what is bad so I don't buy things that are fine l like the starter box I did notice it has two black with yellow come out of the starter box one to the stater other to kill switch could those be wrong ? If anyone can walk me through troubleshooting that would be awesome pm me I can call whoever
Thanks a bunch

Forget using resistance as your test system. To properly test ignition components you need to use a DVA meter. This meter measures the peak voltage output of the various components, and is the only way to test things properly.

For a DVA you can either buy a DVA capable meter, which Harbour Freight have a special on today! or use a normal meter and build a DVA adaptor....

Read this thread about the special -> http://forums.iboats.com/forum/engi...board-discussions/9829945-i-need-a-multimeter
or this one to make your own adaptor -> http://forums.iboats.com/showthread.php?t=374544

Guess I'm not multimeter friendly what does dva stand for ? Maybe a local marine shop can walk me through it

Direct Voltage Adapter. Basically it reads peak voltage... Normal meters read average voltage.

Here's a diagram that may help you.

Well turns out it was the stater only got reading from one side checked my father in laws 86 Merc he had that he is rebuilding it read good swaped out the stater fired right up thank you for the electronic info achris
