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 blue LED should come on even if the bluetooth module's LED is shot. It would be very unlucky for both bluetooth module LED and EZ-B LED to go at the same time.
Personally, I would double check the fuse is OK by carrying out a continuity test on the fuse. If that checks out OK then follow the EZ-B diagnostics and report your findings. My guess would be on the fuse to be perfectly honest. This is all provided the battery is giving the correct voltage at the jack and is fully charged as you stated.
During diagnostics I tested it and theres no voltage going to the spots that dj tells you to check on the board in the diagnostic. Keep in mind that this worked last time I used it.
Unplugged the Bluetooth and plugged it in and still nothing.
Is there voltage on the underside of the board where the power connector is? If not, check your battery. If so, check your fuse.
Me and my Dad just tested the battery pack and IT IS FULLY CHARGED.
I HAVE DONE THE DIAGNOSTICS.
THE TEST PROVED THAT THERES NO VOLTAGE GOING TO THE BOARD.
Sorry to get capitalized but I'm a little off after the ez-b stopped working randomly without using it.
There is voltage on the connector/plug. fuse should be checked how? I put the probes on either side and turned the multimeter to 20v DC and it read what the plug read.
By no voltage going to the board, where on the board have you checked? Have you checked where the barrel jack connector is soldered to the board? Is there voltage? If not then your barrel jack is at fault. If there is, check the fuse, check the voltage at each side of the fuse on the soldered connections.
The V3 is hand soldered, every component on the board can be checked on the underside and replaced if needed. But in order to repair it we must be absolutely clear where the power stops.
Test the fuse by removing it from it's carrier, st the multimeter to ohms and put one lead to one side and the other lead to the other side, it should read >999 (or whatever an open circuit on your meter is displayed as) or a value, the value should be pretty low (may be even as low as 0).
Part 2 of diagnostic video, 2 spots on the bottom side of the board DJ checks. barrel jack has voltage.
LED has no voltage, and neither does the pins on the D ports or A ports.
