Ez-B V3 Pooched?

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.

With regulators to the back:

Left regulator(next to the barrel jack)- 0.40

Right regulator- 0.46

odds are ill be sending the ez-b in to get it checked cause i'm not comfortable with screwing with it and messing it up more than it already is.

You can get the fuse at any auto parts store, any department or grocery store with an automotive aisle, or any electronics store Radio Shack).

@Technopro Autozone, The Source (used to be Radio Shack) or Canadian Tire sell those fuses....

In the mean time, to check if it is the fuse or not there is a risky way... This is bad practice and shouldn't be done without knowing what you are doing as it could cause further damage.

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.

Hmmm, well I think if rather get a new fuse. I'll let you guys know.
