Why you should remove the negative battery terminal before doing ANYTHING!!!!

Typical dome light bulb is a dual contact base, he may have caused a momentary short circuit to ground removing the broken bulb. Sounds far-fetched, but possible that that could have damaged something.

no way - the ecu's not even connected to the dome light. and they're electrically protected against all kinds of "user error", including battery reversal, over-voltage, dead shorts and static. short of direct lightning strike, water damage, or fire, none of which have a single damned thing to do with dome lights, the ecu's not going anywhere and it's /certainly/ not going to be fubared by a bulb change.

Hi, No way? If short caused a surge in the electrical system, anything is possible. In cases like this mostly nothing serious happens but result unpredictable. Protection is not absolute 100%.

Bullshit!!

Hmmm, Live little longer and gain some more experience!

short won't cause voltage surge. measure the voltage across a battery as you increase current load - voltage goes down, not up. only other potential source of surge is back emf from relays, motors, etc, and they're all diode/condenser protected, as is the ecu. bottom line: it's not the dome light.

yeah, it could have been hit by meteorite.

hmmm, Whatever you think. A car battery has lots of energy in it. Think current in this case.

do what i said - measure voltage as a function of load. then report your results.

Hmmm, No, current as a function of load! Do you remember the days of generators under the automobile hoods?

electrical current /is/ load...

take any battery, then measure the voltage as you increase current load on it. then let us know what happens. and how you think high current [short] can cause a "surge".

why? have any basic laws of physics changed since then?

No. Some times in real world things happen where basic law has difficulty to explain how and why. First thing I learned about generator when I was a kid was polarizing.

bull - that is a function of insufficient learning by the observer.

polarizing is not surge!

A short won't cause a voltage surge.

You might want to try starting with just plain thinking.

I do, and there weren't ECUs then. Basing your argument on something that is now non-existant is very telling.

What does that have to do with a car that doesn't contain a generator? What does that have to do with something supposedly related to a battery? Why aren't you answering his questions or providing results of the tests that would prove your "surge" claim invalid?

ok.

You're kidding right?

In article , Gary L. Burnore wrote very little but quoted way, way, way too much.
