After conducting a thorough maintenance routine on a TCM FD30T7 forklift, including an engine wash and oil/filter change, I encountered some unexpected issues. Following the pressure wash, the forklift refused to start, emitting a clicking sound when the key was turned. Additionally, the backup alarm would activate in neutral or forward gear positions, ceasing only in reverse. Upon returning to the forklift after a weekend break, I discovered a total power loss. Despite replacing the battery to restore power initially, the forklift experienced another outage when attempting to start, with dashboard lights failing to illuminate. Even though the battery tested fine at 13 volts and all fuses appeared intact, the root cause of these electrical failures remains elusive. Can anyone offer insight into this perplexing issue?
Ensure that your primary switch is adequately filled with water to prevent stray voltage from causing issues.
Grandpa suggested that your main switch may be filled with water, causing stray voltage that could be contributing to your issues. It may be worth checking if one of the clamps was attached loosely this morning, causing it to "let go" when trying to start the engine. Make sure to inspect the battery cables for any looseness and consider using a multimeter to measure the voltage.
It seems like the issue may be related to wiring or switches. It’s important to note that there are various backup alarms available, each with their own durability levels. While some plastic ones may not withstand power washing, metal ones tend to have better sealing. It is recommended to search for backup alarms and lights with an IP67 rating for optimal performance.
Answer: Answer: Pressure washing and maintenance procedures, such as engine wash and oil/filter change, may have caused water ingress into sensitive electrical components, leading to malfunctions.
Answer: Answer: The clicking sound and power loss could be indicative of water damage to critical electrical connections or components, resulting in an interruption of power supply.
Answer: Answer: Incorrect activation of the backup alarm in neutral or forward gear positions may be linked to water infiltration affecting the electrical system's sensors or wiring.
Answer: Answer: To troubleshoot electrical issues post-pressure washing, you may need to inspect all electrical connections, components, and wiring for signs of water damage and ensure proper drying and insulation to prevent further problems.
