Angry briggs 16hp no spark

help, i have a 16hp briggs twin about a 1975. was running good and then it quit. now their is no spark, we check all the wires looked good. this motor has no points, just a coil on the right side looking at the flywheel. i check it with a meter and from the input wire to groung it is a dead short.
do i need a new coil? oh the coil is the type that has 2 spark plug wires coming out of 1 coil.

thanks larry

Hello: Larry. Welcome to the Small Engine forum.

It is possible the ignition coil died. But before replacing it or looking for problems in all the wrong places, try testing across the kill switch. Also acrss any safety device switches.

Chances are one of those devices may be constantly grounded or contantly opened depending on how it is used in the electrical system.

Use an ohm meter for continuity testing. Take notes if needed. Post back the results. You may find something as simple as a bad connection, defective switch, etc.

It's the simple things to check first before we assume the coil is defective or any other costly part is defective. Good idea to check simple things first, since the engine died suddenly.

Check back on your question several times over the next few days for additional replies.

Small engine repair parts, generic repair manuals and additional help are all available at all local small engine repair shops and or lawn mower repair shops in your area. Shops and dealers are listed in the phone book directory.

Hello Larry!

Here's a quick test to tell if you need a new coil or not. Get a new spark plug and connect it to the lead. Lay the plug in such a manner so that it touches metal on the engine. Unplug the small black wire that is plugged under the coil. Try cranking the engine while watching for spark. If you have no spark, you need a coil. If you do have spark, then you have another problem, like a safety switch, shorted kill wire to the coil, etc...

Glad you got it fixed. I had a feeling it was the coil.
