Vehicle Compatibility
Alternator voltage regulator for select Iveco alternator applications where the alternator uses a matching 2 pin connector in the L CPU layout (plug type IDL-CPU) and the same charging characteristics. Listed for alternator reference ALT1105A and also cross-referenced to VAG applications using OE 038903803F (Audi, VW, SEAT, Skoda) where the alternator/regulator specification matches. Also cross-referenced to Alfa Romeo / Fiat / Lancia OE numbers where the alternator build matches. Specified with active lamp function, very fast 0.5 sec LRC response and short circuit protection. Confirm by alternator label and plug style before ordering.
