90 Amp Altenator
SO I upgraded to a TII altenator today. (90AMP) Was a pretty easy install..took all of 30 minutes and it was running.
However, I started the car and drove about 40 miles and the voltage gauge didnt go up any. Its stayed where it was with the factory alt. Why?
And what are the advanteges of having a 90 amp?
Disadvanteges?

Well... your voltage shouldn't change... it should charge somewhere around 13.8volts.
With a higher amperage alternator, you will now be able to draw more electricity from your alt for those high wattage lights, the stereo system... etc.
In the simplest terms, imagine a garden hose... the pressure at the end of the hose is your voltage. You don't require a lot of water to come out to get high pressure, you can flow 1 gallon every 5 minutes with high pressure from a small hose, and you can also flow 1 gallon in 30 seconds with low pressure from a big hose right? That is voltage.
The volume of water that can come out of the hose is your amperage. The volume is independent of pressure.
The amount of water that can flow through the nozzle at the end of the hose is your wattage. If you take the amount of water the flows out, multiplied by the pressure, you now know how much flowed. The current (amperage) x voltage = wattage. So if you have a 100 watt driving light on a 12v system... you are pulling 8.33 amps.

Just don't stick your tongue on the alternator.......
See a laptop needs about 1 amp (give or take) at 12 volts
a microwave running off 12 volts would need about 30 amps (give or take)
i'm just guessing
See the voltage stays the same, but products that require more power get it from the Amps

Wit' one o' dems higher amperage alternators, yall now gonna be able to draw more electricity from yall's alt for thems high wattage lights, the stereo system an' all that other ****..
If I gots ta tell it like I'd tell my granpappy, imagine the garden hose thats over yonder by the Camaro, no not the runnin one, the one with no wheels... the pressure at the end of the hose is yall's voltage. Yall ain't needin a lot of water to come out to get high pressure, Yall can fill a 10 gallon hat every 5 minutes with high pressure from a small hose, and Yall can also fill a 10 gallon Stetson in 30 seconds with low pressure from a big hose right? That is voltage.
The whole lot o' water that can come out of the hose is your amperage. The volume aint got nothin to do with the pressure.
The water that can flow past your thumb at the end of the hose is Yall's wattage. If yall take the amount of water that come out, times it by the pressure, you now know how much flowed. The current (amperage) times voltage = wattage. So if yall's got a 100 watt driving light on a 12v system... yall's is pulling 8.33 amps.

Small correction
Amps=pressure. What your accessories draw is amperage. You can have a alternator putting out 13.5 volts but very low amperage. Which means it will not
handle any extra drain on the system. IE; lights, stereo, A/C, power windows,etc.
In the simplest terms a higher Amp alternator will enable the charging system to
power all the accessories in the vehicle without putting a excessive load on the Alternator. Which in turn means that the alternator will not overwork its self and the battery will stay fully charged at all times.

um... i'm not sure that's right doc, volts = potential, which is kinda like the pressure, amp is the amount of electrons being pushed out, the original (and the nashville version) is correct. That had me rolling on the floor btw, funny as hell!
