B.Function of main circuit
a. Battery circuit
1. Keep in mind that the battery voltage is applied through the above circuit all the time.
2. A 60A fuse is added close to the alternator, because otherwise part of the harness may get short-circuited
due to the alternator's current generated while the engine is running. In this way, the devices and har-
ness can be protected against burn-out.
