I didnt think these needed two seperate threads, so they're both in here.
Does anyone know if the electric windows are positive, or negative lift. I'm suspecting positive..
Ok, now ammeters. I know exactly what one does, and how to use one however i'm confused as to where and why people fit them in a car.
An ammeter must be wired in series with the circuit its monitoring, so for an ammeter to be any use on a car, you'd need wire it between the body and the negative battery terminal, yeah?
Well, when a car starts it draws massive current - but after that it levels out a lot lower doesnt it. So any ammeter would have to deal with a high current, but then also swap to displaying low amounts of currents. Large currents with decent accuracy sounds expensive, something car ammeters are not.
Also, the cabling to the bloomin thing would have to be huge - unless it has some sort of sending unit.
So yeah, ammeters - is there any possible reason for using on on a normal car?
