RECTIFIER ALTERNATOR

The PATENT PENDING Quick Start™
EXTREME DUTY DUAL RECTIFIER™    
Alternators produce AC current, just like the current
from your house wall outlet. Then it uses a bridge
rectifier, typically with 6 diodes, to convert the AC
current to DC to send to the battery. With Dual
Rectifiers, you get 12 Diodes, which spreads the current
load over a much larger area making the alternator twice
as durable and twice as efficient at converting the AC
current it makes to DC.  The many benefits include: less
heat build up, less current loss, higher amperage output
when hot, more power at idle. Plus, the service duty and
life increases substantially. When the rectifier heats up
the diodes won't pass as much amperage through them,
therefore, the amperage output drops. With our double
rectifier alternator you have twice the amperage carrying
capacity and double the cooling surface area to keep the
diodes cool. This all adds up to......

MORE POWER, LESS HEAT PROBLEMS and
GREATER RELIABILITY.
