1. Power connectivity test
PREFLIGHT CONNECTION TEST OF ELECTRICAL SYSTEMS ONBOARD DRONES.

2. Step 1:
1: Battery
Check connection between positive pole from battery and all positive connections on PDB: There are in total 6 ”+” connections on the PDB. Make a note of measured resistance on your excelsheet diagrams first row marked ”Page 2, Step 1, point no 1”. 1 4 5 2 4 3

3. Step 2:
2: Battery
Check connection between negative pole from battery and all negative connections on PDB: There are in total 8 ”-” connections on the PDB. Make a note of measured resistance on your excelsheet diagram on the second row marked: ”Page 3, Step 2, point no 1”. 1 8 7 2 6 3 5 4

4. Step 3:
2: Battery -
1: Battery +
Check crossconnection between positive pole from battery and the negative pole from the battery. Use the semiconductortest function on your DMM. Make a note of measured END voltage on your excelsheet diagram on the third row marked: ”Page 4, Step 3, point no. 1”.
Repeat the steps above, BUT change polarity on your instrument: Positive on isntrument to ”LIPO -” on the PDB and the negative from your instrument to ”LIPO +” on the PDB. Make a note of measured END voltage on your excelsheet diagram on the third row marked: ”Page 4, Step 3, point no. 2”.

5. Step 4:
Check connection between the ”12V” and ”GND”, make a note of the measured resistance in your diagram.
Check connection between the ”5V” and ”GND”, make a note of the measured resistance in your diagram on the fourth row marked: ”Page 5, Step 4, point no 1 & 2”.
2: 5V Outlet
1: 12V outlet

6. Step 4:
Check connection between the ”12V” and ”5V”, make a note of the measured resistance in your diagram.
Check connection between the ”12V” and ”5V” using the semiconductor test – make an note of the measured voltage in your diagram.
Change polarity and check again as mentioned above.
2: 5V Outlet
1: 12V outlet

7. Step 5: Does all make sense?
Double check everything and compare with another drone –
