Questionthanks eric, since I posted my last question I pulled the flywheel and no points. I have a ring of coils underneath with two wires new question now. Is there a fuse link in this one? what do you think on those Ohm readings?

Question -
I have a B&S m#190407 I think the coil is grounded. With the ground wire removed I have 0 ohms to ground from the ground terminal to engine block
With the coil removed from the engine I have 0 ohms from the ground wire terminal to the iron core. I have 4.5k Ohms from the plug wire to the ground terminal. Am I on target? By the way will this engine have points and can I check the points opening thru the ground wire with an ohm meter?
Answer -
What is the code number? This will tell me if the engine has points. Another way you can tell if you have points is if there is a wire that runs underneath the flywheel.
Let me know the code number or if you see that wire.

AnswerThe wires under the flywheel are for the alternator. There should be a fuse somewhere in the chargine circuit, but that will not impact ignition spark. You may also see a bulge in the alternator wire harness...this is a diode.
Back to the orginal question...I'm assuming you have no spark.
Re-assemble the engine flywheel and ignition coil. With the small wire dis-connected from the coil, install an ignition tester, crank the engine and check for spark.
If you have spark the coil is good. If not most likely the coil is bad.
You can find spark testers at most any auto parts stores.
Let me know if this helps.
