Battery cable upgrade.
Posted: Thu May 28, 2020 11:27 pm
I upgraded the battery cable to the solenoid.
The load with the original cable was around 77Amps when the startermotor ran.
The loss in the original cable was around 200Watt, according to my mechanic.
I went to a local shop and made a new cable that is around 10mm in diameter.
The difference was huge , the Mille started much faster.
12.9V x 77A ~ 993W just after the solenoid contracted the contactors, just before the starter motor starts to rotate.
12.6V x 63A ~ 794W just after the solenoid pulled the contactors together, just before the starter motor starts to rotate, and then with decreasing pole voltage due to. original battery charge.
It is possible to lower the power output further with a well-serviced contactor and solenoid in the starter motor.
