Chris W: Yard Machine MTD, rider, 12.5 HP.
Quit in middle of mowing, electrical problem, turning key to start =
nothing. Pushed it into garage and charged the battery, cleaned teminals,
after an hour, started right up and mowed for about 20 minutes and same
thing - stops dead, key won't start. Charged for 5 minutes - started up
What do you think? Charging system?
Garrett Jdbe: i love vangaurd engines
donyboy73: @pivotboy63 never heard of v-twin flatheads ever
liam collins: lmfao ! this is awsome... so you can save fuel ! one cylender... or you
need power you can put on the 2nd... i think they made a car like that;)
knighthawk86855: yYou have great habits....with putting the bolts in a container....I do the
exact same thing...I learned by loosing bolts from time to time....as i'm
sure you did too...but its awesome to see yu are teaching others to do it
right the first time!!!!!
donyboy73: check the flywheel magnets
Ahmad Abbassi: Good video. I have a question about a Craftsman rider. Battery is amonth
old but does not start engine without jumping with a battery jump pack.
With the engine running I get 26VDC out of the diode. 13 VAC AC wire from
alternator. I check the battery and I get 12,2VDC and 13.5VDC at the
battery when it is running. Is 12.2V not enough to crank the engine? Lights
work. Fuse is good.
647762816: Thanks again.
mbyr31: I'm having a similar problem. My tractor starts and won't shut off with the
key. That ground tab on that diode, I didn't have a wire going to that.
Where does the ground wire to that diode go?
steve spees: Can only start my murry mower by jumping it with a outside battery using
jumper cables. I hook the red terminal from the bat. to the red cable
connection that comes from the mower battery. And then turn on key and
touch the nag. cable from the outside bat. to the outside body of the
starter,and it starts? Thats the only way it will start. THANKS
donyboy73: @Mrtocoolforyou12 yes OHV
Bob Haddock: I had a strange problem with my 2001 sears GT. charging guage was going
negative and did a lot of testing and ...Finally.... pulled the flywheel
off and the Magnets had come off the inside of the flywheel.......$90.00
later it works it works just fine....
donyboy73: @wheely132 only on twin engines
xxtruckin93xx: i got a vangauard nice motor i love em mines 20 years old and runs like a
1899lpv: One question out of curiosity. Why a two cylinders on a riding mower ?
Isn't 12 hp single cylinder plenty for its purpose ? I only see more fuel
consumption here for the same amount of work.
Dnuccio95ZJ: @thumasta666 singles dont have this because theres only 1 coil
ncrdisabled Submarine vet: What year is that engine ? That was some very hard problem to find if you
had a wiring diagram it may have helped.. Great videos!!
donyboy73: thank you sir
laphant: nice vid on diode prob..tnx...good teacher he is..
acscolo: Must see is right. This vid is worth it's weight in gold. I would have
suspected the ign switch all the way to my grave.
th19940305: @FatVsSkinnyShow me two, im 16 and its descent money
donyboy73: @mbyr31 i believe that wire goes to the ignition switch
Farmalls Farms: yes that would be good but if u do that they spray gas out of the carb and
have less than half the power so if u had a 12 hp twin running on one
cylinder it would only have about 4 hp. the car they made like that is the
dodge charger.they run on 4 pistons at low speeds
Jerry McNeely: I have a troy bilt riding lawn mower. I replaced the solenoid on it and
replaced the battery. Now when I hook the battery cables up, as soon as I
touch it with the second cable it trys to start itself. Does anyone know
what causes that? I have been working on this for 2 months and I'm so close
to getting it going.. Please help me out..Thanks
beth fulcher: thank you for the video. i have a cub cadet rider mower. i ran over some
landscaping anti-weed material that tangle around the blades. i removed the
material, but now my mower does not even turn over. any ideas? I am a
novice when it comes to engines, but am learning by watching you videos.
thank you again.
Animal Funnies: Thanks bro fixed the problem. I appreciate your knowledge!
knighthawk86855: you also have great editing skills aswell!!!!
1972FordF150: That's not your every day problem lol
cjn316: Thanks. Turned out it was the safety switch on the blade engagement lever.
knighthawk86855: The best piece of advice I ever got was to "Take Your Time"!!!!!
Sean Moran: Excellent video (as well as other ones you have done). My mower, when I
turn the key, I get one "click" sound and that's it. It was working last
year and then I used your other video to adjust the valves...just replaced
the battery and now it will just "click" once...starter doesn't even move.
Mrtocoolforyou12: is that ohv engine?
jeffy0807: @MrSideboom, that is not correct. 1/2 inch is 12.7mm and a 3/8 is 9.52mm.
so theoretically, u can use metric on imperial but not imperial on metric
in some cases in the smaller sizes. as your get bigger like 11/16, 17mm is
Animal Funnies: Hi i have a bad diode on my riding mower and want to replace but the 2
companies in town don't have any on hand so i want to go to the electronics
store and pick up a diode but they need amp and voltage ratings on it. it's
a Tecumseh OV490EA Can you tell me what the specs are on the diode i need.
Here is the part number Diode for Tecumseh 611161 / 33-420 Thanks!
TheSwete2: hey I have a lawn traktor it is a mtd master cut 115/95 rs with a 12.5hp
tecumseh engine. i have one problem i is back firing hwen im starting så
that is damaging the startet weel how can i fix that problem ???
niper99: no its pervents any back feeding...
donyboy73: @FatVsSkinnyShow thanks for the comment
JOE Z: Thank you for replying. The magnets pull a screwdriver really strong. Other
than that is there any other way to check them?
donyboy73: if there is one yes it could
donyboy73: no just that 12hp in today's Q&A
wheely132: Hey would there be one of these things on my 1990 12 Horse Briggs?
ringbolt9: is the diode for the charging system>
Stevie Bboy: I noticed those iginiton modules on that engine, looks like two single
cylinder coils is that right? so you could probably use one of them on a
single cyl engine.. humm...
donyboy73: could be a faulty ignition module, try it without the positive wire hooked
on, just the coil alone
Carlyle Nelson: my 22hp B&S turns over good but no spark at either plug. Would the diode
JEREMY FOUNTAIN: awesome awesome awesome!
Dnuccio95ZJ: did briggs ever make flathead V twins? i know they had the opposed twins
and those were flatheads
jeffy0807: @jrmcneely, the starting solenoid has welded its bridging together. replace
the solenoid and you should be all good
