This is an aftermarket part for Yanmar heat dissipation measures regulator RX5118 RS5159 RS5121 excavator.
Compatible vehicles: Yanmar RX5118 RS5159 RS5121 excavator dynamo, etc. Size (approx.): Height 65mm x Width 84mm Hole spacing 67mm Connector: 6PIN
The role of a regulator is to rectify electricity and control voltage to a constant level.
Since it is a part that is weak to heat, it is cooled by fins for heat dissipation.
If installed in a place where there is no airflow, it may not be able to dissipate heat, causing heat to build up, leading to deterioration and breakage.
It is very important to install it in a well-ventilated area.
If it breaks, voltage control will become impossible, leading to problems such as undercharging or overvoltage.
If you experience symptoms such as inability to charge properly, headlight bulbs burning out easily, batteries deteriorating in a short period and frequently dying, starter motors failing or emitting strange odors with open batteries, or normal battery lifespan ending, there is a suspicion of regulator failure.
If the failure is left unattended, it can lead to frequent bulb burnouts in lights and other components, and even cause liquid leakage in normal batteries, shortening the lifespan of other parts and causing them to break.
It is important to repair it promptly, as overcurrent and overcharging are often caused by regulator failure.
Even genuine parts with durability will gradually deteriorate and break down with repeated heating.
Repair costs for genuine parts can be high, so we recommend replacing the entire unit with a reasonably priced, high-quality aftermarket part.
It may break suddenly without warning, so it is reassuring to have a spare part in stock for emergencies.
There may be individual differences depending on the vehicle, so processing may be required for installation.
