Generator And Control Box - Triumph Spitfire MK3 Handbook

from this operation, or for any other reason, clean the affected
area with an ammonia moistened cloth.
If, for any reason, the battery is completely discharged, or
reduced to a low state of charge, it should be recharged as soon
as possible; it will rapidly deteriorate if left in a discharged
condition.
When renewing or refitting the battery, ensure that it is firmly
clamped to its platform.
Generator and Control Box (Figs. 49 and 50)
The generator operates in conjunction with a three bobbin
type voltage and current regulator unit which automatically
controls the charging rate to suit the needs of the battery. A cut-
out device within the regulator unit prevents the battery from
being discharged through the generator, when the generator is not
charging. In this event, the ignition warning light glows.
The generator, mounted on the front left-hand side of the
engine is driven by a Vee-belt which is adjusted for tension by
slackening the attachments (1 and 2, Fig. 49), and pivoting the
generator to the desired position before retightening the bolts.
The belt should be sufficiently tight to drive the generator
and water pump without unduly loading the bearings
