Now to light bulbs.

All incandescent light bulbs use tungsten (Wolfram) as the resistance material in the filament. And tungsten increases it's resistance as the temperature goes up.

As for how much amps that goes through a light bulb, that depends on the resistance in the filament and the voltage at the ends of the filament.

Yep x100. At least as I understand it, ohms law does apply. It just doesn't appear that way at first due to the filament changing resistance. It gets a voltage, reaches temp and resistance stabilizes. Current will vary through that warmup process according to ohms law. Current will start high because resistance starts low. If there are voltage losses in the circuit, they are a different matter. As Bill said, it is all about what the filament sees. So first we need to be sure the system is producing enough voltage. Then improve connections to minimize losses. But if the connections are perfect and the wire is too small the filament sees the voltage and asks for more current than the wire can give we just heat up everything but the bulb and still don't get the light output. Your trying to push a golf ball through a garden hose, and everyone knows that requires suction. :D
Relays and 12gauge wire. Done.
Good Morning

Coffee break. Brakes done. I see it needs service, im out of oil,so another trip to town. Better check filter stock too.
 
Coffee break here. Haven't done anything yet. LOL. OK, I did clean up dog poo so I can take the Duster around back by the hose and wash it. Planning to do a show tomorrow. Also, took the wife up to get her car. It passed inspection. Didn't want to say anything and jinx it, but so far it looks like the TIPM is OK. Had it back together since Monday without the horn blowing. Apparently putting the cables together reset the processor. :thumbsup:

Maybe garden hoses in Texas are big enough... :rofl:

Good grief, is the professor involved in the horns on new cars these days ?

Bill

processor, sorry.

Assuming you meant processor... absolutely. Every switch on a new car is just an input.
I don't think anything is controlled directly. ​
Output of the processor controls the relay. Which in this case is soldered on a board. Along with relays for wipers, locks, fuel pump... This is on an 09 Dodge Journey.
