Good To Know
Q: How do I know this regulator fits my Thermo King unit?A: Verify your unit model and alternator part number against the 41-1740 reference. Serial number variations can affect fitment, so confirm before installing.
Q: What happens if I use a regulator with the wrong voltage rating?A: A mismatched voltage regulator can overcharge or undercharge the battery, leading to electrical damage or poor performance. Always use a 12V regulator for 12V systems.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
