I=E/R (go read up on Ohm's law)
Also Automotive grade components are better than commercial grade components, because of the expected operating temperature range.

yes I do understand that with a perfect system that you are correct but every time you hook it up to a car battery you are taking the chance that the manufacturer that built those parts the cheapest didn't put one of the parts with a lower tolerance in your bike. giving out advice that it can not or will not damage the bike can be incorrect. that is all I am saying. it can damage a weak link in the system.

yes, because the few mechanics you "work with" overrides two fully qualified working electrical engineers that have both spent time in the field and not just at a desk. Hell we are first person sources with the technical and professional background to answer such questions. To your, oh my mechanic buddy says so. Find me one credible source because so far you have none. Fatburg and I can testify in court as subject matter experts in electrical distribution systems, I don't think the same can be said for you buddies.
If a part fails from a car battery, it wasn't designed to handle 12v or damaged before you put the car battery on. Electrical devices don't just up and start drawing tons of amps unless you have a short or damaged electrical system in either case the motorcycle battery would cause the same outcome. If anyone shouldn't be giving out advice on this matter, it's you who has no working knowledge of electrical systems except from a craft point of view. Now if you want to say how to change a wire or install a relay, that's different. Talking about how you understand the concepts of electron flow is not in your range of knowledge.
