What does a voltage reading of 24V indicate after starting the left engine?

A voltage reading of 24V after starting the left engine typically indicates that the electrical system is operating within expected parameters, as the nominal voltage for many vehicle electrical systems, including tanks like the T-54A, is around that value.

Specifically, this reading suggests that the system is functioning properly and the ignition of the engine has been successful because the generator is supplying the necessary voltage for the system to run. If there were an issue with the generator or if the battery was being overloaded, the voltage reading would likely be abnormal—either too low or too high.

Thus, the indication of a regular voltage reading supports the understanding that the engine has ignited successfully, leading to the production of adequate voltage by the generator rather than pointing towards any failures or malfunctions. In this context, attributing the reading to a current limiter failure would not align with the expected behavior of the system during normal operations after engine start.
