Hi Sergeant. It has been a while.
This depends on what you are trying to do. If you are trying to check the system, then you are going to need a voltmeter and these couple guides to test the different portions:

I am attaching the wiring diagrams below which will give the other details needed.
However, if you are looking to replace some components of it, let me know what you are looking for and I will get you that detail.
Thanks

About 3 weeks ago our van would not start i jumped it off it was good all day. The next morning, I had to jump it off, took it to NAPA they said it was the battery I had to replace the battery. It was starting just fine for 3 or 4 days I had to start jumping it off again! The right sliding door the spring is broken the door is closed all the way. I don't know what to do.

Got it. Sounds like the alternator is not keeping the battery charged or you have a drain on the battery, so you are correct that we need to diagnose this system.
This could just be a simple alternator replacement but let's start by getting this tested.
You should be able to have the alternator tested at a parts store as well.

However, if the vehicle starts and runs fine all day then there is likely a draw on the battery when the vehicle is off.
To test this, we need to check the amperage when the key is off.
You need to hook a meter in series with the negative battery cable so that we can monitor the amperage that is being used when the key is off. Basically, amperage is the measurement of current flow and when the key is off, there should be very little current flow. Just enough to keep things like the clock and module memory alive so this would be less than 35 milliamps (.035 amps).
I am attaching a diagram below that will help set this up.
Here is a guide that will help with common things that cause this draw but once all the doors are closed, the hood latch is flipped so that it thinks the hood is closed the vehicle should go to sleep.
Once this does the amperage should drop but I suspect you have something that is keeping it high, and it drains the battery.

Thank you Sir.

You are more than welcome. Let us know if you need help after you get the measurement, and we can help walk through that. However, you simply remove fuses until it drops below 35 milliamps and then that is the circuit that we need to find the issue on.
Once we know what circuit we can unplug the components on the circuit until the draw drops again and then you know what component is causing the issue. If all are unplugged and it is still there, then we have a wiring issue.
