CT3 without LoadModule does not work

Piet

Hello to all.

I bought a CT3 with LoadModule (SM-LD-00). (CT3: HW Ver: V1.00.05),
The CT3 arrived with already assembled Load.
After connecting the CT3 to USB-Power Device, it works fine. (Shows the Voltage, the current, ...)
But after disassembling the LoadModule the display keeps black.

I installed the last Firmwareversion (Firmware Version V1.00.61)
Nothing changed, the display keeps black.

After reassembling the LoadModule the CT3 works fine.
But without the LoadModult it doesn't work.

What am I doing wrong?

Can anybody help me?

Hello Everybody,

I could solve the Problem!

The first Step was to find the Installation Guide. The Link is placed in bottom of the Page of "AVHzY USB Load sm-ld-00 mode for CT3" (https://store.avhzy.com/index.ph ... oduct&product_id=54):
"AVHzY CT3 SM-LD-00 Installation guide: https://youtu.be/Qxx2zxMGTFo"

Watching the YouTube-Video:
At 0:54 a Riser is installed for the LoadModule
(After this the 4 Risers in for the 4 Corners are installed.)

From the other Direction (disassemble LoadModule) it means that the Riser for the LoadModule has to be disassembled.
I did not disassemble this Riser. The CT3 worked fine without Back plate.

After assembling the Back Plate the CT3 did not Work.
The Reason: The Plate causes a Short circuit by touching the Riser for the LoadModule and the Risers at the Corners.
I decided not to remove the Riser for the LoadModule,
but i stucked a tiny piece of Tape on the Back Plate, directly above the Riser for the LoadModule (when the Back Plate is assembled). The tiny piece of Tape isolates the Riser from the Back Plate.
The short circuit now is suppressed.
Now the CT3 works fine with assembled Back Plate!

Now Assembling or disassembling the LoadModule goes faster, because the Riser for the LoadModule can keep at its place.
