<h1>This is my product.  Installed on same circuit where previous battery meter was, in 36V golf cart.  Meter reads 36 volts, 100% charged.  Batteries are drained at least 50%.  How do I get the device to correctly display the remaining battery capacity?  If you cannot respond with very clear and specific steps, I am going to send it back and, obviously, post a negative review on Amazon.</h1>
