Electrical Indicating System Specification
This SAE Standard describes those factors which affect the accuracy and reliability of voltage indicating units and electrical indicating and sending units for fuel level, pressure, and temperature suitable for off-road, self-propelled work machines as described in SAE J1116 and agricultural tractors as defined in ASAE S390. Indicating units are divided into two groups, fully sealed and partially sealed. Serviceable lighting is not covered by this document unless otherwise specified. No ISO document has been found to be compatible.
This standard is being revised to provide a specific reference to ASAE S390 for agricultural tractors. This change is necessary as the intent is to retain agricultural tractors in the scope of this document. This is required as a future revision will be proposed for the removal of agricultural tractors from the scope of SAE J1116.
