The turbine engines on the
Cold War Air Museum,
Mi-2 use an electric starter and the original batteries in the original aircraft have been replaced with sealed batteries of higher capacity.

In the preliminary wiring of the battery modules, we used some light duty automotive terminals that were readily available. After a series of starts, we found that these particular connectors were "self fusing" at a load close to the start demand of the engines. After enough starts, the terminals cried "enough!" and disconnected themselves.

The series links inside the battery boxes have now been replaced with heavier gauge wiring and terminals.
Thank's Brad!
