Briggs & Stratton Ignition Diode Repair On Lawn Tractor




What do you think about this video?

James Sparacco: hey don, I am trying to work on a scotts by john deere lawn tractor, this guy said that if I got it running I can have his snapper lawn mower. the lawn tractor will not crank over with the key so I tried to hot shot it, still nothing, so I poured gas in the intake and jumped it right to the starter, it cranked over but didn't start which leads me to belive that it is a wiring problem. so today I go down there w/ some fuses and I switched out the 30 fuse with a new 30 fuse and with no hot shot I turned the key and I heard a pop, I looked down at the fuse and it was blown so then I took a thin wire stripped the ends of it and stuck it in the fuse socket so then I cranked the engine and it started up and ran for 2 seconds and shut off, I went to unplug the homemade fuse bypass and it was very very hot, any suggestions?

Jerome Cooper: thank you for the video

Liberty Patriot: One cylinder not firing;..does not save any fuel, it just gets sucked into the cylinder, does not burn and cleans the walls, rings/piston so they rub themselves to pieces!

Liberty Patriot: Which way are the diodes positioned? anode/ cathode?
You could get 2 properly sized diodes @ Radio Shack and bypass the defective diode module and save big buck$!

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 again.  HELP!
What do you think?  Charging system?

Bradford Frotten: Thank you for your help!

MIKE CHIESA: VANGUARD OHCV

cjn316: Thanks. Turned out it was the safety switch on the blade engagement lever.

donyboy73: if there is one yes it could

Carlyle Nelson: my 22hp B&S turns over good but no spark at either plug. Would the diode cause that?

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

666mrjimbo: STARTER COULD BE BAD TOO DOUBLE CHECK ALL WIRES MAKE SURE BATTERY IS @ FULL CHARGE TOO

666mrjimbo: TRY CHARGING THE BATTERY OR CHECK THE WIRES MAKE SURE THEY ARE NOT LOOSE

My Videos: 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!

donyboy73: you're welcome

My Videos: Thanks bro fixed the problem. I appreciate your knowledge!

1899lpv: Maybe you sheared the ''key'' on your crankshaft and the mower"s timing is out of sync

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. Any ideas?

donyboy73: thanks for watching!

wcjcnc: Great video as usual. I know it is VERY time consuming to shoot and edit videos like this. I really appreciate the time you take to do this. I run a small engine repair shop and your videos are a valuable tool.
