This procedure is assuming you have pulled break release / kill handle back to the run position. £22.99. I plan to remove the resistor from the spark plug cap (and the steel cover) and use a resistor spark plug. One has been run occasionally to keep it ready for power outages. I have been servicing mowers for many years, including the old breaker points ignition systems, and the easiest way I have found to test these things is by the idea of “seat of your pants technique.” Primary coil resistance hook up 1 lead of the multimeter to the electrical tab and the other lead to the iron core making sure your meter is set to Ohms. You can remove or disconnect the kill switch to test if it is the problem. Briggs and Stratton Ignition Coil Testing. Poor starting. The best option is the replace the coil and restore the spark. The coil of your 10hp Briggs and stratton likely has a different reading then the smaller coil filmed in the above video. But, I get 0 ohms between the stop-switch connection and the coil body – which surprised me as I thought that that was the connection made by the stop-switch (ie it grounded the coil to stop the engine) – can you clarify that one again? It’s an inductance shunt. I don’t know what else to do. If the kill tab is hard shorted to the coil body, and the coil body is not isolated from the engine when mounted, then it seems to me the coil cannot possibly work, the coil is grounded to the block at all times, it’s like leaving the kill switch permanently in “kill” position. Ignition Coil Primary & Secondary Resistance Testing - YouTube Thanks for posting this anyway – makes life easier. The coil can still be faulty when within range but it much less likely. I’ve replaced the fuel valve, spark plug and ignition coil so far. What you are saying might sound stupid but the fact is that this is about the best way to find out if anything is happening from the coil or not, especially when the spark is weak, or can’t be seen due to lighting problems, or when the wires can’t be properly secured/grounded to do the test.

May need to be in a relatively dark place to see spark. I have a Briggs and Stratton 4.5 hp mower. the old coil is 4 k and it does work. I have two of them that were gifts. If the magnets are strong and the coil and spark plug is new then the most likely issue is incorrect too large air gap or incorrect wiring causing the coil not to work properly. An ignition coil that has the wrong internal resistance often exacerbates this condition and leads to a poor-running engine for which you can find nothing wrong. Other coils often have different readings. I have replaced the spark plug. Would a simple rubber cap be OK or will the engine/ignition be damaged? Armatures are often packaged with a shim to assist in setting the gap. Do you mean set the meter on the 25 kohm range, and the coil should be between 2.5 and 5.0 kohm (1 kohm=1,000 ohms)? Between the kill switch and the HV it also reads 6.5kohms. If it does not start compression may be low. Thank you! It started right up after that and ran much better, but then just shut off and won’t start. Flywheel magnets good and have been cleaned. One it will eliminate the possibility of engine accidentally starting and eliminating any compression in combustion chamber. 592846 Supersedes 799651, 691060 ARMATURE-MAGNETO Used on vertical V-Twin engines 400000 series, i.e. With another priming, and a good solid pull, the engine turned over and started immediately.

Noticed that the magneto surfaces that “face” the flywheel magnets were quite “cruddy” with crap like dried grass(? There is no spark. I checked the on-off switch and pulled the kill harness off with no success. Get it Thursday, Dec 17. Shouldn’t matter where you measure. The resistor would change the reading, However if you get no reading after the resistor it would suggest the resistor is damaged. The remaining 4kOhm is the resistance of the plug cap. My coil reads 10 kohms but more significantly the kill wire is 0 ohms to frame, which I suspect means it is FAB. If you do get shock. Set the multi-meter to the 20 k ohms setting. It is unlikely that the new coil is also bad it may just be an incorrect reading, Or the coil readings are different for outboard engines. Does anyone know the resistance values for the coil alone between A and B A and C B and C Thanks. I recently purchase a new coil and got around the same reading. I can get a new coil Monday $48.00, but hate to just throw parts at it. Australia Post Is Experiencing Delays Resulting In Longer Delivery Times. Hi, i have a Briggs & Stratton 13,5 OVH and I need to replace the sparkplug-connector (don’t know the name..) I have two of them. Used it twice this 2017 season, no issues at all, then come to use it for the third time (and just two weeks after the last time) and it simply will not start. I checked the magnets on the flywheel and they were still strong enough to hold a screwdriver, but I noticed a smaller amount of black crud on the flywheel along this edge where the flywheel would pass the magneto, so I cleaned that off too with the same emery paper. This will not determine if the coil is failing when hot, You could put your coil in the oven at around 60 Degrees for a short time then test it at that temperature to determine if anything has changed. I first remove the boot over the spark plug then remove spark plug. I would investigate the Off/On Switch contacts and make sure they are not incorrectly configured or damaged as this could be causing the no spark situation. £14.99 £ 14. I have an older 2hp Briggs engine, model 60102, on a lawn edger, which I am trying to get going. If there is continuity between the connector and the ignition coil frame there will be no spark as the coil will be grounded. OK, all the resistances check out properly but I still get no spark. Also, the 2.5-5 Kohm resistance is for one winding. For the coil I read a value of 2.79. If you have not replaced the spark plug that would be the first thing. I am not familiar with the oil level switches so cannot offer any help there. If you can stand a little shock, then here it goes. when bulb depressed Craftsman 19HP BRIGGS & STRATTON WITH 42" MOWER 107.27768 Operator's Manual (99 pages) .

Hi, the kill wire should be around haalf ohm when the killswitch is not grounded. I was kind of surfing this site and read all kinds of ways to test Magneto’s or electronic ignitions. With that done, I reinstalled the magneto, paying attention to the “cylinder side” / “this side out” lettering on it, and used a piece of thick-ish card as a gauge to set a gap between the flywheel and magneto (as seen on another video online), as I tightened up the bolts. I have set coil gap at .012″. I have a old Briggs and stratton 8hp (193707-0370-01)and have no spark. (Prices may vary for AK and HI.) If the kill wire connector coming off the coil going to the primary coil is suppose to kill the engine – only when the kill wire is grounded to the engine – how can it have continuity at all times?”?? I am assuming you need to replace the spark plug boot. Thanks, Yes the multi-meter test gives a good indication of whether the coil is working or not but it is not 100% accurate. Plug gap is .025″ & condenser gap is .020″ & condenser points have been cleaned. Still no spark means it is highly unlikely that the cap linked to different parts in specific manner me.
