"Craig... The amplifier (pulsepack) simply provides voltage to the coil, and since the engine idles, I'd consider it to be okay.
However, to be on the safe side, check the amplifier out as follows.
& #40;Voltage Drop To Battery Capacitance Discharge)
& #40; Pulsepack When Electric Starter Is Engaged)
& #40;J. Reeves)
On the older Battery Capacitance Discharge ignition systems (1968-1972), the electric starter reaches a point, even with a top notch battery, whereas the starter will draw excess voltage/current/whatever which results in a voltage drop to the pulsepack. The cure is to purchase a diode which is capable of handling 12 volts and installing it between the starter terminal of the starter solenoid (NOT the battery cable terminal) and the wiring terminal that supplies voltage to the pulsepack.
The diode must be installed so that the current flows from the starter terminal of the solenoid to the pulsepack... NOT vice versa. When that diode is installed in this manner, when the key is turned to the start position, the voltage that is applied to the starter is also applied directly to the pulsepack via the diode effectively eliminating the voltage drop and energerizing the pulsepack with the required voltage needed for its proper operation.

& #40;J. Reeves) my question is do you install wire on larger cable on starter side of solenoid or small terminal on solenoid for cranking. before you connect diode to12 volt power supply.
