The excitation current connection is mandatory because the combined current requirement of the two melts of about 12 A effectively discharges the battery. (believe me; there is experience)
EARTHING MUST BE PROPERLY! — changings working fine now
Relay connectors
– 30 = main current (directly from the battery, remember the fuse!)
– 85 = ground (provide proper grounding)
– 86 = control current (eg behind the ignition switch)
– 87 = outgoing plus cable
