Product Description

Triumph TR5-250 Alternator Conversion - 17ACR and 18 ACR Replacements - 6 Cylinder
From 15 AC to 17 ACR or 18 ACR Alternator:
The Triumph TR5 and TR250 was fitted with a Lucas alternator and charging equipment as standard. The original specified alternator was a 15AC type with an external regulator. This was replaced on the TR6 by alternator types with internal regulators. The low power output (28 amp) 15AC alternator can be replaced by the later higher output internally regulated type if some minor electrical wiring modifications are carried out (see Alternator Terminal Conversions).
