WebMar 21, 2024 · When you lift your foot off the accelerator or touch the brake pedal, the new bigger alternator pumps about 200A into the starter battery, and the instant voltage can rise to in excess of 15V. That’s 3000W, or 4hp. The alternator is only about 75% efficient at these higher levels, meaning the amount of power taken out of the drivetrain is ... WebAug 1, 2024 · The signal comes from the alternator regulator and the PCM modulates the signal to ground at a frequency of 126-128 HZ. The higher the duty cycle, the higher the alternator voltage set point. To diagnose the system: Key off. Disconnect the 3-pin GEN COM connector. Measure the voltage at the center pin at the alternator.

WebSmart alternator varies voltage by temperature, so does the FJ. Smart alternator has voltage controlled by the ECU, so does the FJ. Smart alternators reduce charge rate near full battery capacity, so does the FJ. Seems most comments seem to think charge voltage is everything, current is also a consideration. WebOn these vehicle it set a code either stored in the ecu or actually set a check engine light. These vehicles had the computer replaced to fix the car. Altering ground points or adding accessories to existing ground points can change the smart charge for the battery. Install hid kits at your own risk. WebFor many Ranger owners, the solution was a trip to a Ford dealer where the computer could be re-programmed to make the alternator perform in a traditional (non-smart) way and keep everything purring along.
