Agreed. I wouldn't bother starting my truck to jump my lawn tractor.

Although a car alternator is "capable" of charging at 100-amps... It doesn't put out anywhere near that at idle.

[@Leonardokite]

I would be willing to bet that almost everybody does it by the normal start your car method. What you say makes total sense and I would have not thought about that either. Thank you Steve for your service.

Yes, most bikes and garden tractors have shunt voltage regulators and they will get abused by a vehicle’s charging system, especially when the volts fly over 14.2.

[@canoetipper019]

Years ago I went to Crappy Tire and bought one of those solar trickle chargers (when they were on a crazy sale of course) and mounted on a pole at the end of my garage. Ran a cable into the area I park the lawn tractor and installed a power outlet protected by a fuse directly to the battery. It works even in the winter. (I have a Berco snowblower mounted on the tractor) Keeping the vehicle off is a smart idea...I've had to do that too. Cheers from NB

[@gordsmith7708]

Cheers 🍻 man ,you're exactly correct man been a mechanic for over 40 years and I have expressed the very same boosting practice . Even better yet charge your battery over night so the alternator on your lawn tractor doesn't have to do all the work and possibly over heat and do damage to it . Cheers 🍻

I burned up a starter on a 80's G6200 Kubota doing it wrong. Last year traded it in for a John Deere X570 which cuts better/higher but I miss the sound of that diesel engine and no-E gas is a 25 miles drive from my place. Hey glad you're back!

[@jje8182]

Did what wrong? Hooked it up backwards? You'll never burn up a 12 volt starter from any 12 volt system. You could have 500 batteries hooked up parallel which would still be 12 volts and the starter would still use the same amount of amps to run as it would with one battery.

[@WJCTechyman]

@@jje8182 Yeah, and overall, that Kubota tractor (and even the GR series today) is better than most of the plastic that John Deere sells now. Especially since Deere has gotten so cheap it's moving a portion of its manufacturing to Mexico.

You beat me to it, and it is very true.

[@Austin18025]

Yep, too many amps.

[@integr8er66]

​​​@@JoeBMancoThis is NOT very true. just because an alternator can produce 100 amps absolutely doesn't mean it will. Unless the internal resistance of that battery is exceedingly low, which is no different than if your car battery was 100% dead then it could produce 100 amps, but very quickly the voltage in that battery would raise and the current would drop off, so start the car, just don't leave the cables hooked up all afternoon once it's started, but even then the mower battery is shot already so over charging it isn't really a concern as far as damaging it goes, and you absolutely will not damage the mower charging system, esp since it is basically a coil and a bridge rectifier

[@integr8er66]

​@@Austin18025No, amps don't just flow, they are based on resistance. So nope

[@thrivelawncare]

Love this guy's no nonsense straight forward videos

[@Harleylovinchelley1]

Thanks for sharing this info. There is even more to jumping other machines. A lot of newer electronics are designed to only have 12 volts at start up from the vehicles battery. Cars, motorcycles, lawn equipment, etc. have electronics that can be damaged if there is more than 12 volts at start up so the donor vehicle should NOT be running in any case. Once any vehicle is started the charging system will replace the electricity used but the 14.5 volts only goes to the battery NOT the other electronics. If the donor vehicle is running you will be sending 14.5 volts to everything on that dead vehicle. I say that because I recently saw a memo from corporate Harley regarding the jumping of a dead battery on a Harley.

[@OldJoe212]

Good tip. I have and extra car battery that I have fully charged for this. It's easier to carry a spare battery than jockeying around my truck.

[@moabfool]

I just touch the positive cable to the starter. I used to fry alternators in my Geo Prizm every time I'd jump someone. When I left my engine off I didn't have problems. Thanks for letting me know why.

[@Montana_horseman]

This is great info Steve! I've been jumping my riding mower with one of those emergency jumper battery packs and cables. It works like a charm and is rather low powered, it might start my car but likely not my truck. It's more than strong enough to start my mower though. When the mower starts I disconnect it right away. It cost me maybe 10 bucks more than the mower battery but it has ports that I charge my phone, cameras etc on and I can throw it in my truck or car in case I or someone needs a jump. Budget met while getting my mowing done. 😉

[@paulhighbarger3356]

Exactly!

An angle that I had not considered. I do go by the rule of not starting the jumper vehicle unless I have to though. Thanks!

[@preblecs]

This is why I have one of those battery jumper packs kicking around the garage. I almost never jump start off of another vehicle now. So convenient on the first start of the season, if I need to jump start, to just take the battery jumper to the shed and jump start the mower with it. Takes less than 60 seconds. I keep one in with me on the motorcycle too. The small jumper packs have plenty of juice for a bike.

[@XspeedXracerX]

Great tip! Wish I knew this sooner because I tried jump starting my rider mower a couple days ago and noticed the jumper cables smoking due to rapid overheating! I had the truck engine running of course!!!

[@WJCTechyman]

If they were smoking, you ran too narrow a gauge of cable to start that tractor. Also, with the right gauge, when the tractor has a fault somewhere (probably a short in this case) the cables will melt. For most tractors, say starting around 8-10 hp you should be running minimum American 6 gauge cable to the starter motor and back to the battery. This also works for jumper cables. Using beefier jumper cables helps transmit more current to your boosted vehicle. Starter motors on tractors can possibly consume at least 100 Amps at start due to working against the static inertia of the engine.

[@nathanfisher1228]

That's great advice Steve! I had no idea! I thought your video was going to be not to set your truck on fire! That's exactly what my Grandfather did when he got confused. Every time he stood up, on the mower the safety seat would turn it off. So he decided to reach up and throw the leads off but they sparked up the dry grass under the truck and set the engine bay on fire! Bad day.

Hello Steve, I briefly thought that this was the first video that I had to contradict because I see absolutely no problem with two alternators running in parallel. Then it occurred to me that the voltage regulation works differently with small engines and if the charging voltage from the alternator (truck) is slightly higher than that from the charge controller (riding mower) it will "burn up". (sorry if my English isn't good, I just ran it through the translator.) Greetings from Bavaria and thanks for the great videos :)

How weird! Yesterday (when you released this) I went to fire up my less-than-a-year-old Husqvarna mower for my first mowing of the year and the battery was dead. I had used it about a month ago to cut up some residual leaf clusters, and everything was fine then, but testing it with my old-school load tester the battery apparently has shorted internally, so it's boat anchor bad. I'll be calling my dealer tomorrow for a warranty replacement (there's less than 10 hours on the mower), but I wanted to mow so I got out a bench charger I have that has a boost charge of 15 amps. It couldn't overcome the ground enough to give me more than solenoid clicking, so I swapped batteries with an old mower I have that I use to pull a tree-limb gathering wagon around the yard for pre-mowing cleanup. Got the job done, but once again it's weird how the algorithm seems to read your mind sometimes. Great tip, and this of course also applies to jumping off vehicles, if you have a large enough battery in the donor vehicle for cranking without the engine running. It's definitely gentler on the charging systems!

[@eddievilla1584]

Great video. This is also the way to jump start a motorcycle. In fact you should never jump start a car with another car running. If you do need to run a car, be ready to pull off the jumper cables as soon as the dead car starts up or else you may need to replace one or two burned out alternators.

[@StevesSmallEngineSaloon]

Can you explain how this would damage an alternator on either engine?

[@eddievilla1584]

12 volts + 12 volts = 24 volts, Todays car's charging system are not made to deal with such loads. Cars back in the early 1960 and older had generators and those charging systems could handle that kind of abuse.@@PonderingOne

I had to do this with a dual fuel gas generator several times. The factory battery the 3600 watt generator came with is apparently undersize for cold weather starting. I like to camp off grid on our private campsite we developed on our property over the years. I park my truck parallel to the trailer and just pop the hood on the truck, hook up and away it goes. I would need to customize the outside frame to fit a larger battery. If the generator didn’t have a 30amp outlet to fit the camper power cord I would have sold it by now.

[@johnmilner7603]

I use a jump box. I did notice that before buying a new battery for my John Deere X300 I was connecting the jump box to both + and - terminals of the dead battery and it eventually wore out the module under the dash. So from then on if I needed a boost I would use a good GND on the X300 before starting the X300. I also keep the X300 battery water level maintained with distilled water. I noticed one yr all the cells were low. Since then it’s been great.

Totally agree. Treat the donor vehicle as a battery jumper pack. Battery jumper packs do not have engines. For a different reason, that the 100amp Alternator in the donor vehicle cannot supply 500amp cranking current. I have seen an alternator fall to pieces while the donor vehicle is running due to Electro-Dynamic Braking in the alternator. Keep the donor engine OFF!

I’ve got a good story for you Steve. So a couple summers ago I was either putting my battery on a charger or jumping it off every time I went to cut my grass. No telling how many times I had done this so one day I unhooked my charger and jumped onto my mower, a Scott’s 16hp 42” cut and I hit the switch and KaBoom!!!! The battery exploded! It sounded like a 12 gauge shotgun had been fired right under my seat! I felt the hair on the back of my legs part because that’s where the deck height adjustment is. My ears were ringing from the blast! I was lucky that the battery was dry. I had charged it so many times that it had no water left in it. It split the battery diagonally and couldn’t trade it in on a new one it was so bad. I’m surprised that the cops didn’t show up because I was in my garage when I started it and I’m sure the blast echoed through my neighborhood! Enjoy and learn a ton of information from you!

Another good tip is to get a professional quality set of jumper cables. i have seen too many elcheepo cables that were fried and people couldn't figure out why. Car being jumped needs way more amperage than el cheapo cables can provide thus causing the jumper cables to overheat and more than likely the vehicle being jumped will not get started.

With my minimal understanding of electricity I'm glad I guessed correctly before you got into the vid.👍

[@FaithwalkerTodd]

I work with Solar Panels and charge controllers and I recognize two charge controllers can charge the same battery or one charge controller can charge several batteries. When charge controllers are charging the same battery bank and there’s more than one charge controller they’re just contributing to the total and monitoring The voltage of the battery the whole time. The batteries themselves are the buffers that separate the charging systems. But even if you had two charging systems working together but one is much stronger than the other it would mean the stronger one would be charging the battery system faster. It’s just a combination. So if one charger is pushing 100 A and the other charger is pushing 15 Athe total will be 115 A going to the battery bank. It’s not like the hundred amps coming out of the one charger is going to go across the batteries and affect the charging system of the tractor. In this case you have two battery banks, the tractor has a small battery and the truck has a much larger battery. The truck battery is at a higher voltage and because it’s so much more powerful it will instantly push the smaller battery up to its voltage, which will send too much power to the weaker battery Because they’re not evenly charged. So for that reason it would be damaging the battery on the tractor and nothing else.

[@borisjankovici662]

Unless there's a limit on the rate of charge of the battery, it doesn't matter. They're both lead acid batteries... He is missing that the cold cranking amps of a vehicle battery are 350 to 600 amps while alternators generally aren't bigger than 150Amp (and that's on the high side). The battery can supply far more current than an alternator so this point of turning off the vehicle is moot. The battery on the tractor IS being charged by vehicles battery simply by being connected.

[@FaithwalkerTodd]

@@borisjankovici662 all batteries have a limit or a maximum continuous charge rate. For a typical battery found in a pick up truck you would expect this rate to be somewhere around 20 A.

Never thought of this before . If both were putting out the same voltage then I cannot see a problem, but they seldom will , add to that they both cycle up and down in voltage many times per second , and it could be a concern. I don't get the concept that a higher amp alternator will drive current into a lower But just for the heck of it I likely will boose from a non running vehicle, he is right that there should be no need to run it
