Doing This Will Destroy Your Cars Electrical System ejonesss: what about voltage spikes of say 24 or even 36 volts can that fry the computer(s)some cheap cupholder sized jump starter units use 12 AA cells in series being 18 volts and if there is a condition for example where there is a faulty connection on the battery the 18 volts will go into the car rather than the battery causing damage to the electronics. many of the cupholder jump starters are designed with cigarette lighter plug so you dont have to get under the hood and mess with the batterywhile the AA cell is rated to handle a few milli amps to 1 amp of current in a disposable or 1 time use rescue jumper the rechargeable ones use lithium cells capable of delivering many amps in a short amount of time. if there is a bad connection on the battery for example corrosion on the terminal and the user does not know about cars enough to be able to fix it them self they may try to use a cupholder booster the resistance of the battery will be high enough that the battery will not load down the booster to bring the voltage down to a safe level and possibly fry the electronics. the disposable ones probably cant deliver the current needed to overcome what little load that a severely corroded battery could put on the booster so it may not be too much a problem but the rechargeable ones can easily deliver the current to overcome the load of a severely corroded battery and the voltage could go too high. another note. the rechargeable boosters i have seen a youtuber who goes by the name bigclive tear down was only a 3s lithium pack but i imagine there are boosters that use 4, 5 or even 6s packs. so i wonder how protected from over voltage computers are.

if you can destroy the computor system that easy then the computor is weak and faulty why wasnt it made to withstand something so simple like jumping a battery? well because theres money to be made on labor and replacing weak and faulty parts a fuse of some nature could have been installed to protect the weak computor so why wasnt that built in? why wasnt a simple cover installed over the negative post on battery to prevent putting a jumper clamp on that post? thus you can put that clamp on a bracket which also could have been installed butt wasnt an automobile designed for a non mechanical person to damage it by doing something simple should have been recalled from the start especially considering the outrages prices on them But then theres the warranty that will be nicked picked and wont cover the damage because the owner jumped the battery incorrect, so now have to pay out of pocket and he got no money so goes home mad and beats the hell out of the oldlady and then gets the gotdamn cat and throws it in front of a gotdamn moving truck really mad now and looks at the damn dog but the dog sees him and jumps the gotdamn fence and runs down the damn freeway into the horizon and still running to this day wheewhooo

I owned an RX8 for 14 years. They dont necessarily burn oil because of bad apex seals. Its because they have actual oil injectors that intentionally inject crankcase oil into the engine to lubricate those apex seals. Also had a problem with carbon build up making the apex seals stick over time. But beyond the engine, I also had problems with a weak starter, pathetic fuel pump, short spark plug life (expensive, weak ignition coils, airbag sensor, seat position sensor, an ECU I had to replace with a junker, and a few other things that had nothing to do with the actual engine. Really sensitive to brand of O2 sensors as well. Just not Toyota quality engineering. I have a 2018 Camry now because that RX8 drove me to it.

Fusible links are the same as a fuse, they are just in a different location, applied differently, but the two blow in the exact same way. A fusible link is just a different gauge of wire, its less accurate than a fuse and can provide far LESS protection. It has no way to tell what way the current is flowing, lmfao. As far as the whole reverse polarity. Every alternator has a slight bit of AC leakage, this isnt enough to fry a computer system as its typically in the milli-volt range, and most well designed computer systems will have a diode to help prevent reverse current from frying them. Whether the manufacture elects to have a diode on the negative side is another story.

Quite wrong about the Mazda rotary engine. They were designed to burn some oil as a protection for the chrome lining of the rotor chamber. Watch the oil level and you will never have a problem with excess oil consumption. Since the early 1960s I have built, owned or driven many different race and performance cars from Porsche 962s to Ferrari 512s and my 1982 RX7 is right at the top of my list. With slight mods I surprised many a TransAm and Vette from traffic light to traffic light. Never had repairs other than maintenance. Only sold it to make room for a restoration project.

Are the VM Diesels in the Jeep and many other vehicles OK The Diesels? As far as I understood Fiat always made good Industrial Diesels? Somebody the other day said Fiat now owns VM Diesels? This is the only problem I have with your videos. I realise time is a problem but simply saying Jeep is crap and Fiat is crap is a bit too general. Yes I know Fiat cars have always left a lot to be desired. All I know is 40/50 years ago Fiat Tractor Diesels were exceptional. Often did 15, 000+ hours when most would be lucky to make 8/10, 000 hours. Economic and lots of torque also.

Just bought the 2019 highland SE 39500 yes talk them down. sticker was 43680. 00. 4180 off the sticker. Give up a 2003 suburban for it. ya ya my Q is nuts. It was my fathers go through. 155. 000 on it. Clean but not clean enough to be reliable to do a lot of travel live in the Northeast. yes pick up 1/2 the cash and financed through our credit union. Question do you think Im making a mistake buying a brand new car I looked at once with 30, 000 miles on them and it was only three to 5000 difference why not buy new. ? Thanks Great videos Hope youre killing it on YouTube

I bought my daughter an emergency set of cables. I noticed the IMPORTANT INSTRUCTIONS ziptied to the cable. It showed A) jumping a POSITIVE GROUND car FIRST and then B) jumping a normal Neg Ground car. What the Hell? Are we jumping a Aircraft Carrier or a import from the 50s? Any non experienced person following instructions is likely to fry a car. I ripped off the instruction, and showed my daughter how to do it. Chinese out of context instruction. It was in English so the instruction was meant for the US/Can market.

hey scotty. im in the caribbean where its always hot, so we never have to use the heater in our cars we only need to be cool inside our cars and not hot. i have been considering an old 5 series bmw from 2004 because i loved them forever but it can be expensive to maintian down here. but if i dont go with the bmw should i go with nissan or toyota taking into considering the temperature of our climate here always being hot and also considering trying to save money and getting the most reliable vehicle? thanks, andre

My father built up a couple of ex War jeep kits, and when he was finished building them he started with 20 kits, and sold 19 complete working. The last one was the spares mule, so, when the supplier eventually sent the spares ordered as they were assembling the others, he ended up with 2 jeeps instead. Could not sell the one, as it was literally made up entirely from spare parts that came extra in the others, and thus was not in the import system as it had no VIN. It became a shop mule.
