On this job I did the bits the customer couldn’t do and combined 2* 90amp Prestolite alternators with an Adverc twin system. 2* 160 amp split charge diodes. 50mm charge leads. 60mm pulley for alternator driven off the small crank pulley and 65mm pulley for alternator driven off large crank pulley and Gates XPA Quadpower Belts. 700AH Rolls AGM Batteries, Victron monitor.
Adverc Voltage adjusted for the batteries. System works well achieving 180amps just off tickover and customer happy.
