I recently purchased a wheelchair elevator lift from a company in China. My partner installed the lift and did the electrical wiring, the lift works however the electronics need tweaking. The lift works well if someone is in the lift, it goes up and down as it should. However, if I am downstairs and the lift is upstairs it takes well over an hour for it to come down and the reverse is true. I do believe that this is an electronics problem so I’m seeking a solution.

Hi, there I'm Peter, I am very experienced in circuit design problems, I always tackle these everyday cause I design circuits all the time, you can check my portfolio (That is the work I have done) and also check out my reviews, I didn't ask for them, they were genuinely given to me. I assure you, you will love my work, like others have. I truly believe it should be an electronics problem, probably something interfering with power transfer. I use simulation on many softwares like LTspice and Pspice on candence to back up my designs too! I really would love to work with you and I can't wait to hear from you, please leave a message. Thank you! Peter

Wow !! My friend, this is a more difficult problem than it sounds. First, the problem must be located, for this you have to do a couple of basic tests, once the problem is located, the difficult part comes, modifying the circuit to eliminate it, this is difficult because the manufacturer never reveals its electrical diagrams and the user (you in this case) must have basic knowledge of measurements and welding. I have seen similar incompatibility issues on other equipment such as treadmills. I don't dare to assure you that this project can be carried out remotely, but we can do something: you send me a detailed description of the problem and the documentation that you have, I'll tell you the tests you have to carry out and you do them, the process would be trial and error. Do not assign me the project or pay me milestone, only if we can solve the problem you do it, I will trust in your word. In the worst case, we must redesign the electronic circuit but this is complicated because I must know each component that I must handle, power consumption, which parts I could reuse, etc. I am a Telecommunications and Electronics Engineer. Best regards
