alternater ?
first off im running new wiring throughout my engine bay and was curious if there is any effects positive or negative with running a larger power wire from the alternater. its only a 60 amp chrsysler.
also would delta winding the alt instead of standard produce more amperage.
ive done a delta wound before but had no way of finding out if it produced any positive results. i was told it generally bumps its amperage up 30

Doc here, :pimp:

The larger the wire the more current it can handle, with heat loss, heat does no useful work and consumes It is always a useful thing to go as large as practical when replacing the wire..

On the alternator winding..Why go there, you can probably upgrade to a higher output alternator as cheaply..


There are basically two ways to wire a 3 phase alternator, star ( or Wye) and Delta. With Delta you get lower voltage but more amps. In star you get higher voltage but less amps. You can calculate these by using the square root of 3 ( or 1.732 ). Each coil set is a "phase" of the alternator so when you measure voltage,ohms or current to test one phase of the alternator you would measure the "phase". Once you know what the output will be from one phase you can calculate the "line" output of either delta or star.
For more on Alternators:Alternator Basics Read this and decide..

Remember, how ever more you bump up the output, your internal components must also be upgraded if they are to last..

seems to me i should just go get a higher output alt or just run capacitors. i dont have much to my set up but i figure amp draw on a compresser and a 1500 watt rms system can draw much more than my alt can output id probably need 2 caps and a 150 amp alt maybe even a capacitor to my compressor.
