The Power Distribution Module (PDM) integrates
these electronic features found on Polaris ATVs;
Rectifier/regulator, Solid--state circuit breaker
output, Starter Lockout output and Engine
temperature controller. There are no service parts
in the PDM. If the PDM fails, it must be replaced.
Following are overviews of the various PDM circuits
and how they function:
Regulator
The rectifier converts the the output of the 3--phase
alternator (COIL 1,2,3) and applies it to the battery
and the PDM loads. The regulator monitors the
battery voltage and shuts off the rectifier when
full--charge exists on the battery. SCR’s are used to
connect and disconnect the alternator from the
battery to achieve regulation of the battery voltage.
The regulator shuts off current on the BAT+ pin if the
battery exceeds the over--voltage threshold. A high
voltage transient willcausetheregulatortoturnofffor
a short period of time. If there truly is an open battery
