For Yanmar heat dissipation measures, regulator RX5118 RS5159 RS5121 mini excavator aftermarket part.
Compatible vehicles: Yanmar RX5118 RS5159 RS5121 mini 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 at a constant level.
Since it is a component that is weak to heat, it is cooled by fins for heat dissipation.
If installed in a place where there is no wind, it cannot dissipate heat, heat will accumulate, and it may deteriorate and break.
It is very important to install it in a well-ventilated place.
If it breaks, voltage control will become impossible, leading to problems such as undercharging or overvoltage.
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 in the case of open batteries, and normal battery lifespan ending suggest a regulator failure.
If you leave the failure unattended, it will frequently cause bulbs in lights to burn out, and even normal batteries may leak fluid, shortening the lifespan of other parts and causing them to break.
It is important to repair it promptly, as overcurrent and overcharging are often observed due to 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 it in stock as a spare part for emergencies.
There may be individual differences depending on the vehicle, so processing may be required for installation.
