Your video saved me $65 on not having to purchase a new coil. Thanks again Rob for kindly sharing your expertise with us.

Guys like you are the DIY's go to in diagnosing problems such as this, thanks for not being a turd and taking the time to help people out.

Thank you for your support and tuning in it is definitely appreciated

Thank you sooo much!! You would not believe how many videos I have been looking at to figure out my issue. Mower cranks, starter turns, but ride on will not start. Dodgy PTO switch seemingly getting in the way of it all working. Machine non-responsive for couple months, fixed by pulling PTO up and knocking it closed with a hard whack. Starts immediately. 👍🙏

This totally helped me out today. Thanks brother!

I'm not a mechanic but had my uncle help & I had a loose nut to the stator or something that fixed my mower. So must've vibrated loose

Great diagnosis, simple but effective!

Nice video to learn from I know I had a Riding lawn mower few weeks back would not do nothing when you hit the key . checked every safety switch on it. Come to find out that switch that plugs in the hood lights the black wire was broken. Hood was shut on it I guess. Thanks for the video.

VERY VERY GOOD INFO.

Very informative thank you

*First thing I do on a new/old machine is bypass the seat switch. Who wants the engine to die every time you jump off to open a field gate?*

Good info, thanks man!

I have a mower that the coil keeps going out on. The coils I’ve gotten are new and match the owners manual part number. What can cause this issue? I never thought to meter the new coil for continuity, can they just be junk from the start? I didn’t hook up the kill wire on the last new coil and it still never sparked. My gap is set correct on both coil and plug. Am I missing something?

[@jewermank8536]

I'm fighting this same issue, thanks man

[@jewermank8536]

I ended up ordering a new off brand ignition switch. We'll see...

[@youtubestar]

Just make sure you check all your safety switches. I literally had the same problem this morning. Except mine wasn't doing anything when I turned the key I was pretty convinced I had a locked up starter but I played with the switches and still nothing and then I went over the switches one more time and lo and behold it was one of the safety switches on the control arm on the mower

[@jewermank8536]

@@youtubestar thanks for the advise. I did check the seat safely switch, no change there. It's a 2005 JD that was given to me. Ever since I got it 2 years ago, when I turn the key to off, it takes 2 full seconds before it starts shutting off. Always thought that was odd, so I'm hoping it's the ignition switch finally giving out

[@jewermank8536]

Got the new switch installed. It wasn't the switch. I also ordered a new electronic control unit module. It runs again. I was shocked, that part is $89.

I have an issue with a chainsaw and I am fresh out of options. Spark was intermittent so I cleaned the coil contacts. I now have good spark and I cleaned the carburetor, but the part that bewilders me is I usually spray starter fluid in the carb to determine a carb problem but it won't kick even when I spray with starting fluid. There is some scoring on the piston head and wondering if it could be that, but wouldn't it at least kick and stall?

Sherlock Holmes of engines etc!

[@bretttoups5744]

What if your seat switch for a gravely has 3 wires? How to test or jump that out?

[@andystevenson7756]

Hi what do I do if I still don't have spark with a brand coil and that ground unplugged and a brand new spark plug??

[@youtubestar]

Check your fuses. Ignition switch. All the wiring. You said it's a brand new coil?

[@andystevenson7756]

Yea I put it on there gapped it still didn't have spark??​@@youtubestar

Buy a multimeter! A simple circuit test can make all the difference.
