Well sir, I'm not charging you $125 for a simple ground wire...I'm charging you $125 for the 20+ years of troubleshooting knowledge. ;) Nice catch here.

My old instructor from the 70's said over and over. Check you battery check your ground. No matter what technology it is ---that is still true today. Good video SIR

For 2 years I've been racking my brain trying to figure out this very problem. I've been to my local Toro dealer countless times describing this problem, only to be told "You'll have to bring it in." You summed up the problem, and fixed it in less than 5 minutes. I too had resorted to a battery tender. Thanks for the solution!

My Kawasaki FS600V would not charge above 12.6V at WOT. Stator output was 33 VAC, so I ASSUMED it was the voltage regulator and purchased a new one for $80. Once installed, no change to low charging voltage. Watched this video, and although my grounding jumper was present, I tried the screwdriver test - voltage instantly jumped to 14V. Thanks for your video; I was out of solutions.

What blows my mind is all the people that work on their own lawn mowers without any knowledge of how they work. Bought two Scag mowers that were filled with simple to fix problems. Can see the getting frustrated and just sale a good mower to replace with new.

Good catch, I pickup a 2015 toro time master from this guy, no start, no spark condition, for 50 bucks, he thought he had blown the engine, turns out, and this had me stumped, so I thought I'd share it with you, incase you ever run into this problem, no start condition, was caused by no spark, I changed the coil after I did the coil unplug test, still no spark, so I went old school and grounded the sparkplug to the block, and got a bright blue spark, long story short, the head gasket blew, and was run that way for a week or two, and that caused oil to seep onto both sides of the gasket, and the head bolts, cause a no ground condition for the sparkplug, I clean everything up, new gasket, and she started right up, boy was the guy angry I got a 1500 dollar almost new time master for 50 bucks, the only reason I told him was I had to go back for the bag which his son found, and he asked if I ever got it running..... LMAO

I got the same engine , but it discharges at higher revs . WTF ?

My battery was loosing its charge and going dead. Finally found a blown fuse hidden . Scag liberty z.

50 cents worth of wire and a couple of terminals to correct the issue. Sounds like the other tech needs electrical 101 !!!!

Not grounded

This video is precisely why KZread is so valuable. Thank you for sharing!

Great video, exact problem with the Kawasaki engine on my toro zero turn mower, just fixed. Thanks.

Man this is gold, thanks for posting this video, first thing I'm going to check on the mower after I already replace wiring harness flywheel and some other parts that the mower repair guy already replaced, my deck is electric burn power like crazy full charge battery last around 4 hours on the mower, but this video makes a lot of sense now on my mower.

I love when a problem is so easily corrected. Sometimes you just can’t see the forest through the trees. Thank you

Wow the onboard charger is a new one on me and i been mechanicing for 20 year's 😂🤣 thats unbelievable someone actually did that and excepted failure on simply charging the battery 😅👍👏🤯

Mind=Blown... Thank you Sir!! This just completely solved the charging issue I've had, never would've thought to check for this before. I owe ya one

Bro I got to hand it to you! My dumb behind has been chasing and electrical issue for about 4 hours now and lo and behold no ground wire on this Kawasaki voltage regulator. Made one up, put it on, everything's charging! Thanks again for keeping everything so damn simple for us overcomplicated fools lol

I just want to say thank you I had a Scag walk-behind that I put on electric start on I've got tired of pulling it lol and I could not figure out why my battery was draining it wasn't charging thanks to your video everything is working like it should and it's charging. Thank you again

My 2016 Exmark vantage w the FX691V had this exact same prob; the strap was missing I added one and now it works as it should. Thx so much for this video! This saved me a lot of headache.

You, sir are a BOSS mechanic!
