Charging system upgrades usually involve the replacement
of the original generator based system with an alternator based system.
Automobile generators rarely output more than 25-30 amps, which is usually
adequate for a stock vehicle, but can fall short when high energy ignitions,
large electrical cooling fans, and stereo systems are installed. Generators
are also prone to failure when driven for extended periods on hot days.
Since modern alternators usually produce a minimum of 60 amps (and as
much as 150 amps), they can easily handle just about any demand the
vehicle owner can put on it. For the Sunbeam Tiger, I like to use either
the Ford/Motorcraft or GM/Delco units. GM/Delco units are internally
regulated and require no external voltage regulator, thus reducing wiring
and component costs. For Tigers, we sell an aluminum alternator bracket
modeled after the Tiger MkII original (see parts
section). We can provide specially fabricated brackets for other
vehicles as well.
