XML Electrical System

[TooLowGear]

Hey everyone I am still working on my APU but right now I am making the electrical system for the aircraft here is what I have so far:

BATTERIES:

(L:BATT1 ON, bool) 0 !=
(L:BATT1 TOTAL TIME, seconds) 1 <
	if{
		44(>L:BATT1 AMPS, amps)
		24(>L:BATT1 VOLTS, volts)
	}
(L:BATT2 ON, bool) 0 !=
(L:BATT2 TOTAL TIME, seconds) 1 <
	if{
		44(>L:BATT2 AMPS, amps)
		24(>L:BATT2 VOLTS, volts)
	}

I will not be doing any voltage drop calculations because the batteries will be NiCd and they do not experience a voltage drop as they discharge.
LOAD:

(L:BATT1 ON, bool) 0 !=
	if{ 
		(P:Absolute time, seconds) (L:BATT1 TIME, seconds) - 
                (>L:BATT1 TOTAL TIME, seconds) 
	} 
	els{ 
	        (P:Absolute time, seconds) (L:BATT1 TOTAL TIME,seconds) - 
                (>L:BATT1 TIME,seconds) 
	}

I borrowed that from the stopwatch xml in the sdk but I do not know if that is correct for what I need. That is supposed to be a timer which will store how much time the battery has been on and thus calculate the amps remaining in the battery

eventually i would like it to implement the timer with the drain code

<!--This gives the drain in amp-seconds--!>
(L:ELEC LOAD, amps) 3600 / (>L:BATT1 AMPSECS, amps)
<!--This is the actual battery drain--!>
(L:BATT1 AMPS , amps) (L:BATT1 TIME) (L:BATT1 AMPSECS , amps) * - 
(>L:BATT1 AMPS, amps)

any help with the timer would be awesome. For some reason it is the most difficult for me to grasp.

Thanks in advance for the help.

Counter

I did a search for some timers and I am still having a hard time understanding how to make a counter in FSX.

I tried

(A:GENERAL ENG THROTTLE LEVER POSITION:1, percent) 5 >
if{
(E:ABSOLUTE TIME, seconds) (>L:OLD TIME, seconds)
(E:ABSOLUTE TIME, seconds) (L:OLD TIME, seconds) - (>L:TIME DIFF, seconds)
}

But I get a 0 value. The display I am using is the default fuel pressure readout changed to (L:TIME DIFF, seconds). I either get a 0.00 or 0..(-0$%@ kind of readout. All I need to a timer that counts up from 0 using the real sim time, not the update section.

Thanks for any help!

Absolute Time

Well I made my own absolute time variable

(E:ZULU YEAR, number) 1 - 31556926 * (E:ZULU DAY OF YEAR, number) 1 - 86400 * + 
(E:ZULU TIME, seconds) +

and I still get the same result as if I had used (E:ABSOLUTE TIME, seconds) using this readout

I am getting .,(-*,(

I have no idea what that means but it can't be good. I calculated the absolute time for 10/4/2009 0000z to be 63390240208 seconds.
