REGULATOR RECTIFIER

The rectifier converts the AC current to DC current by passing 
the AC signal from the stator through diodes in a bridge 
configuration. The regulator is used to limit the DC voltage to 
a stable 14.5 Volts. This is necessary because the AC Voltage 
can range from 0 - 80+ volts that is directly proportional to 
engine RPM.

CAPACITOR

The function of the capacitor is to act like a battery in a non-
battery system. The capacitor makes the chassis side power 
signal stable. WIth out the capacitor in the system the unit will 
not run correctly at idle.

TESTING THE CAPACITOR

1.

Use a 12 volt battery and hook up the positive (+) to the
Red/White wire and the negative (-) to the brown wire. Let
the capacitor take a charge for 10 seconds.

2.

Using a multi meter check the power that is in the
capacitor. The power may slowly go down.

CHASSIS RELAY

Controls the power distribution to the chassis separate from 
the rest of the system. The relay will close at a set RPM, when 
the system can support the chassis load, and open when 
engine RPM drops past a calibrated histories or 700 RPM. 
Voltage Boost kicks in at 700 RPM, the relay opens, the stator 
power is boosted and allocated to the fuel system and ignition 
components.

CHASSIS GROUND

Located behind the left hand foot well the chassis ground 
provides current path to ground. If ground is disconnected, all 
the current will run through ECU and damage the internal 
components of the ECU.

OIL LEVEL SENDER

The float (A) moves up and down the sender shaft (B) and 
ECU sends a signal to the MFD when the level get to the point 
where you need to add more oil. The oil level signal is 
measured in resistance, FULL is open and <10

Ω at lower 

level.
