SCOTTY AI TROUBLE SHOOTING INSTRUCTIONS & DIAGNOSIC PROCEDURE
When Scotty AI is not charging or performing as expected, scroll to the bottom of the main page and read the reported fault. The figure shows a list of failures on the main page. • After reading, goto: Potential Solutions Guidance to understand what the fault means. • The following text shows an Enumeration list of Fault Problems and possible Solutions. ‘Feature In’ Activated: The designed feature allows the receipt of stop charge requests from the house battery when the CanBus connection from the battery management system (BMS) is not in use. • It is recommended to verify the condition of the house battery; • If this feature is not required, you can disable it from the system settings. ‘Inverted Feature In’ Activated: This functionality is similar to the 'Feature In' feature but with an inverted operation. • It activates when it detects a 0 V signal in the 'Feature In' wire. • It is recommended to verify the condition of the house battery; if this feature is not required, you can disable it from the system settings. If this is selected and nothing is connected to the feature-in, Scotty will naturally stop! HS (High Side) battery preventing charge: A high-side battery preventing charge means that the house battery BMS is not accepting a charge, which may suggest that the Battery is already fully charged. • However, it is also possible that there may be underlying issues with the Battery's health. • Therefore, we recommend thoroughly checking the house battery's condition to ensure optimal functionality. Alternator current limit is configured to 0: The alternator current limit pertains to the maximum current drawn from the alternator. • The limit is currently set to zero, indicating that no charging is taking place. • To modify this setting, please navigate to the 'Tuning page' where you can adjust the alternator current limit to the desired level. Alternator temperature protection is active: The current indication is that the alternator is overheated, so you cannot use it now. • If the alternator's temperature is not high, there is a possibility that the temperature probe may have become disconnected. Therefore, we recommend checking the wiring to ensure it is properly connected. • Most Engines run around 90ºC under the engine bay, but some vehicles go as high as 105ºC. • We recommend increasing it to 120ºC in this case. HS Charge Voltage is reached: Based on current readings, the high-side battery voltage has reached the maximum allowable charge voltage. • To modify this setting, please access the designated 'Tuning page.' • However, we strongly advise referring to the battery manufac- turer's specifications before making any changes.

An Error Occurred: We suggest checking for error messages, which may indicate that the HS or LS terminal is not adequately connected to the Battery. • To begin troubleshooting, we recommend inspecting the fuses and isolators and ensuring they function correctly. Voltage Sense Wire disconnected: The current indication suggests that the sense wire is not detecting sufficient voltage. • It may be due to a disconnected wire or a depleted starter battery. • If the cause of insufficient voltage is a depleted starter battery, it may not be possible to charge it via the current system. In this case, we recommend connecting an external charger to increase the starter battery voltage to an acceptable level.
