      Again thank you Scotty!
      What I'm curious about is in my Mitsubishi Montero 95 with 249k miles. It has a DEFINITE oil leak and regular gauge issues (reads half gas tank or below on a full or oil pressure at min when its above, while driving). Thinking is reaching its "dead-line" but the thing still runs. Any ideas of what to get tested or what to do to get it in shape?

      That's the second amp clamp you have showed in less then a month. So which one is better?

      In the early days of computers in cars, in the '80's, initially, 12 volts was used, rather than 5 volts, but 12 volts would make the circuits run too hot, so the computer circuits wouldn't last long or worse, become intermittent, where they'd start mysteriously working, when you brought the car to the mechanic! That's the main reason, that computers in cars switched to 5 volts. Also, 5 volts is pretty standard in computer circuits nowadays, so there's a lot more to choose from for the designers and engineers. They initially went with 12 volts, so they wouldn't need the extra power supply circuitry to reduce the voltage, but because of the heat, it turned out better just to go ahead and reduce the voltage to 5 volts.

      Here's what happens, when you touch a spark plug wire. To put it in medical terms, it knocks your d!ck in the dirt!

                I really do appreciate your comments and views on vehicles. Also I showed my son last weekend the same thing about touching the positive and ground with my fingers on the battery. He said he was scared when he changed his sisters car battery out.

                            Electricity is like a river at a consestant angle. V is how wide the river is and A is how deep it is and the amount of water flowing is your power that can be converted into heat or mechanical movement. Picture a river 12 foot wide = 12v and 6 foot deep = 6 amps how much water flows? Now picture an impossible river 12 foot wide and 100 foot deep how much water flows? 12v is incapable of providing enough current to harm you but keep in mind the real danger is current. The relationship between V and A (current ) is sometimes misunderstand and alot of folks bealive Voltage is what harms you but actually its the current ( the amount of electrons flowing thru you ). If it was possible for 0.01v to supply enough current it too could be fatal.
                            I'm just say Voltage is only part of what makes electrity fatal current is the bigger part of the equation higher voltage allows more current.

                                "A short circuit is a problem in an electrical circuit where two or more wires that are not supposed to come in contact with each other touch. A short circuit can result in a very high current flowing through the circuit. ... A "short circuit" also happens when there is a bypass of electrical current."

                                                  Wait! Wait! Wait! A 12 volt Direct Current (DC) car battery won't harm you as Scotty said. BUT if you should have something in your house that reads 12 volt AC (Alternating Current)(plugs into a socket) DON'T play around with it unless you know what your doing!

I really enjoy watching this, being educated on how to deal with cars. I have a question I have a 96 Honda Accord four cylinder and my dashboard lights are starting to go out what should I do?. I truly appreciate the fact you put these videos out and hopefully you continue to do so. Thank you 🙏🙏✌️
