Adapts 10SI thru 27SI two pin (flat blade terminal) Alternator Voltage
Regulator Plug to CS130-CS144 4 Pin alternator plug.
For Vehicles that DO HAVE a "no charge" warning light on the dash,
There is No Resistor in this Harness
The CS130 and the CS144 must have a resisted ignition wire
to activate the alternator. If you use a
12volt ignition lead to the "L" Plug terminal to activate the CS
series alternators is will make the voltage regulator fail over time.
It must be a resisited ignition wire to activate te alternator.
The SI series alternator does nto require a resistor at the activation lead.
