After realizing that wall-e was being neglected I decided to pull him out. I realized that I had an alternative battery so I unscrewed the battery pack from the adapter and screwed in the new pack. I plugged it in and...
It didn't turn on...
I played with the wiring.
Nothing...
I switched back to the original pack.
Still nothing.
I thought it might be an adapter problem. So I took my dads multi meter and discovered...
I don't know how to use a multi meter.
I turned the multimeter off and then inserted the probes into the jack on the adapter and found arcing. It was making sparks as current travelled through the multimeter.
This tells me that the adapter is getting current. So now I'm wondering that maybe my ez-b is pooched? Its not getting hot and nothing is abnormal on the board, so im left wondering.
1. How to perform a test to see the problem?
2. How to use a multimeter.
EDIT: I did the first part of the ez-b diagnostic check and it checked out. Now i'm at the part where it should plug in and flash the lights and it doesn't.
Part 2 shows that theres .01-.03v going through the ez-b. It sits at 0 when not touching.
AKA red from battery was red but went to black on the connecting wire.
There was no puff of smoke. How do I test the regulators?
Use your multimeter, on DC and measure between the pins of the regulator. I believe the centre pin is ground so between that and each pin either side on both regulators. Or use the main ground where the battery connects.
I'm not being funny and hope you don't take offence to this but if you are asking these questions I highly suggest you learn how to carry out basic functions with a multimeter before probing your EZ-B. There are literally hundreds of videos on youtube which explain it all in detail. There are text tutorials, I even linked you to a very comprehensive Spark Fun tutorial.
To minimise the risk of further damage to your EZ-B you really need to know the basics of using a multimeter. I would also recommend finding the datasheet on the regulators used on the EZ-B, there are at least two different topics which cover the regulators in the last month or so, one by Mel here and another by Pravnav.
Left regulator(next to the barrel jack)- 0.40
Right regulator- 0.46
Edit: this the right one?

Set the meter to a current setting (amps)
Attach the one probe to one side of the fuse holder.
Attach the other probe to the other side of the fuse holder.
Apply the power to the EZ-B.
If it turns on and lights up then the fuse is the only thing gone.
Keep a constant eye on the meter and if the current rises to anything above 1A immediately disconnect the power or remove the meter.
Basically, doing this will bypass the fuse. It will result in no over current protection to the EZ-B or it's components and you will be relying on the meter to tell you the current draw of the EZ-B.
Disconnecting the battery or removing any of the multimeter probes will open the circuit and shut off the EZ-B in the even of a high current draw however chances are your reactions are a lot slower than the speed of which current flows and pops components.
Again, this is bad practice and should not be done if you are not comfortable doing so. I cannot accept responsibility if this causes further damage and chances are any warranty would be void after doing this. Do it at your own risk.
THANKS FOR ALL THE HELP!
