Outputs and Drivers

The Spitronics TCU’s were designed to drive most standard solenoids found in transmissions directly. Some are On/Off solenoids that is switched with 12V DC and other are control solenoids that is pulsed with a Duty cycle or PWM Pulse Width Modulation pulse. The control solenoids normally have a lower resistance and is never controlled at 100% duty cycle. This may damage them. Other drivers are used for dashboard LED’s and Speedometers.
