4.4.3 Fuel Injector Polarity
The Multec 3.5 Fuel Injector utilizes a 2 terminal electrical connector.
The terminals correspond to power and ground and are not polarity
dependent for injector performance, yet a polarity has been established to
reduce the severity of a coil short to the injector body from a full-on
condition to a blown fuse. See Figure 4-5.
Best practice is to maintain consistent polarity during all injector testing
and evaluation to minimize potential performance variation.
