Alternator and Battery testing
When the generator is closed, we find battery status using the table.
| Voltage (V) | Charge (%) |
| 12,6 | 100% |
| 12,4 | 75% |
| 12,2 | 50% |
| 12,0 | 25% |
| 11,8 | 0% |
When operational the battery either overcharges or undercharges. From the respective condition we add or subtract +- 1V.
