2.0 Inputs
• 0.00 Alternator “R” Stator
- This Input monitors the Engine Speed via the Alternator R Stator Pulse. The R
Stator Pulse typically is a –1.4-volt minimum to +15 volt maximum square wave of which the frequency varies
relative to engine speed. The engine RPM is determined by counting the pulses of the Square wave and scaling
ratio to engine speed. The alternator signal voltage should read 6.5 – 7 volts at the 0.00 input terminal with a
digital volt ohmmeter.
