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.
How to perform a test to see the problem?
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.
The best and easiest way to check a fuse is by continuity. Just about any multi meter can do it. All you have to do is set the multimeter to the proper setting and touch each lead 2 both sides of the fuse. Most multimeters will beep or buzz if there is continuity. That means the fuse is good and there is a connection all the way through it. When a fuse blows there is a little strip of metal that melts between its two legs. When that happens you will not get continuity and the multi meter will not buzzed or will show zero. 0 in the world of multimeters is also called null. You can use this method on circuits of any kind or header pins to see if you have any breaks, bad joints, open or broken wires.
Also, you can look at the fuse and see if it is burned out. The little wire in the center will not be connected to both ends.
That's not always true. Sometimes it's very hard to see. I've had fuses that were connected and looked to be ok only two tests bad. It just happened to me 2 days ago. However I have to admit that it was a glass slow blo fuse and not the automotive type that is used on the EZB. Then again I did have a blown fuse on one of my ezb's and I had a very hard time seeing that it was blown. I ended up testing it like I describe above just to confirm it was bad. Also when testing fuses for continuity it is best to remove them from the circuit or you could get a false reading.
So, was it the fuse? Did you get it working yet?
Haven't got a new fuse yet. Going out Friday so my get the fuse then. The fuse when you look closely is broken right on one of the bends.
@Technopro Looks like you found your problem... Occams Razor (when things go wrong, usually it is because of something simple)... In your case it looks like a blown fuse and not a duff board...
Got the fuses. put one in, and it works. Guess I need to look closer next time. Ill give it to the first person who mentioned the fuse. rryerson mentioned it first but in all fairness it was a guess because you said you hadn't even seen an ez-b before. Mel was second so ill give it to him.
THANKS FOR ALL THE HELP!
I just realized all the wires I have to plug back in. stress
