Hello, good/you afternoon/days/nights
someone for those coincidences will have the manual workshop of the Mercedes Benz 1520 truck of 1970.
I tell you: I have problems with the start I feel that the starting engine rotates without force, it is a 24V truck of two batteries (new) both of 12v and 90amp, this truck brings 4 cables to the battery one goes to the starting engine, another goes to the body and the other 2 To a box I imagine that it is the从24V到12V的转换器，但是当我测试此盒子时，如果有人知道如何修复此问题，我不会给我连续的2条电缆，
这真的很感激
