Technical note
As an on-site technician, after performing a conductivity test on particular HV (High Voltage) fuses and not finding any of them blown continue the following analysis.
Analysis of Error Test voltage N reachd - Plug3 with car or tester
1. Check all screws are properly tightened.
Figure 1.
2. Measure the voltage from power modules 9-12 from the start of the charging session.
If the measurement is lower than ~ 480V then the problem is coming from a power module.
Figure 2.
3. Measure the voltage after 1000V D7 diode from the start of the charging session.
If the measurement is lower than ~ 480V then the problem is being caused by diode D7.
Figure 3.
4. Measure the voltage from K14 from the start of the charging session.
If the measurement is lower than ~ 480V then the problem is being caused by K14.
Figure 4.
5. Measure the voltage from D2 from the start of the charging session.
If the measurement is lower than ~ 480V then the problem is being caused by D2.
