Question: My friend's father is the owner of an electric wheelchair, but in the last few days when he uses it or even when charging, the horn sounds on and off. Could you please let me know what could the problem be? ~Billy

Answer: It sounds like some sort of wiring problem, but please contact the manufacturer of the wheelchair directly as they are experts on their products. Does you friend's father still have a warranty covering the wheelchair? This is even more of a reason to contact the company he bought it from directly, as a warranty could fully or partially cover any repairs to his chair.
