What is the voltage signal pin on DA230ps00-0

Can anyone help me what is Dell's XPS 1730 AC power adapter signal pin voltage for the battery is. There should be 2 voltages - 19v + ? - on the end of the connector that goes to the laptop. Since the original DA230ps00-0 no longer work I cannot measure the voltage. Since I'm overseas and not in the US, I cannot find DA230ps00-0. So what I did is buy Alienware power adapter GA240PE1-1 with a rating 240 watts 19.5v 12.3amp and 8volt signal pin for the battery and replace GA cable for the DA cable. But I think the signal voltage for the DA adapter is greater than the GA adapter and now I have no voltage in the signal pin of DA240PE1-1 after briefly charging the battery.
