Exactly where did you go to train as a mechanic or are you a backyard mechanic?

A battery is a battery is a battery. Here's a little experiment you can try at home with something cheap.

Find something that is powered with one small battery that requires little to no amperage, measure your voltage and current. Now go out and get like 30 or 40 of those batteries and hook them all up in parallel and see what you voltage you have. Now hook that parallel bank of batteries up to your device and measure voltage and current again.

Ahem...

The FBI would call that a clue...

if you reread what I said, you are taking the chance that there is no weak part in your system. I have seen it happen with my own eyes. I have worked with mechanics that have 20+ years in the field that can back me up.

ask any EE if you can jump a bike with a car battery, in theory it works, in practice I have seen electronics fried.

just because you have never seen it doesn't mean it can't or hasn't happened.

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.

What you don't seem to get is that 12v's is 12v's. The current draw from 12v's is based on the load resistance.
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.

Alright now kids, Ohm's law has just been quoted, this thread has officially been hijacked...let's close it down before fatkid gets pissed and starts Trunking EVERYONE!!!!

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.

huh huh, Trip said "flow"

Did it more often on my old bike, but I've done it, I'll admit.

WTF happened? I just skimmed over page 1, all was well and good, then I get back here to the last page and WHOAH... shit all over the place!
