Good morning, I would like to know which fuses and cables dimensions I need for THE START ASSIST function on cyrix relais 12v 120 amper. If I got a exhausted start engine battery, a lot of current will pass through it.
Now I got four 50 amper fuses on the positives of the three batteries (1 engine and 2 services) and on cyrix..... I'm worried thei will broke, if I start engine with Start assist function.
Thank you for your answer.
