What to check first
Note whether shore power is connected, which lights are affected and the battery monitor reading. Inspect only accessible, unenergized connections visually.
When to get help
Have the battery and charging system tested before buying parts.
Your RV’s make, model and component instructions control. Stop use and seek qualified help for propane odor, smoke, active electrical danger, unsafe braking or other immediate hazards. This guide does not diagnose your RV or establish part compatibility.
Next step
Check the exact component manual and model number before following a model-specific procedure.
