TR2-4A Alternator in a dynamo casing. This unit has been designed to look the same as a dynamo but is in fact an alternator inside with an internal regulator. The output is set to 28-amp so that the wiring and ammeter as fitted to TR's TR2-4A with cope with the current. With the greater output provided by an alternator, it is feasible to add extra electrical services to your car, however be aware that the original wiring has insufficient capacity to accept additional loads. Revington TR recommends incorporating our Auxiliary Fuse Box kit RTR8270K with the alternator installation.
NOTE: If a thin belt conversion is fitted and you wish to dispense with the original fan arrangement and bolt the crank pulley direct to the crankshaft, order short bolt kit RTR1027K. See below
