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.
