When a red light on the dashboard stays on, it generally refers to the coolant temperature warning light. Here are the relevant explanations: 1. Overheating: When the coolant temperature warning light comes on, you should stop the vehicle immediately. This is caused by excessive coolant temperature, which may lead to the cylinder head gasket being blown, resulting in the mixing of coolant and oil. In such cases, the engine will require major repairs. 01 Engine malfunction indicator The engine malfunction indicator is used to display the working condition of the vehicle's engine. 2. Self-check: When the vehicle starts and performs a self-check, the engine malfunction indicator will light up. If the engine is functioning properly, the light will turn off automatically after startup. If the engine malfunction indicator remains lit after startup, it indicates that there may be a mechanical issue with the engine.
When I noticed the red light on the Harley dashboard staying on, as someone who frequently repairs motorcycles, my first thought was that this must be a warning signal. A red light usually indicates an urgent issue, such as low oil pressure or engine overheating, which could lead to severe mechanical damage. If it's an oil warning, insufficient oil levels will increase engine friction and cause temperatures to soar; if it's a battery warning, there might be a problem with the charging system, leading to starting difficulties or even stalling. For safety, pull over immediately—don't push through. Check the owner's manual to identify the warning light's meaning; if you don't have the manual, use your phone to search for common Harley fault codes. Then inspect the oil dipstick or battery terminals for looseness. If the issue is confirmed, it's best to have a professional mechanic diagnose it, especially since Harley's electronic systems are sensitive and DIY repairs can complicate things. Ignoring it may lead to costly repairs or accidents, so timely action is crucial.
