Thank you for responding. Motor just stopped. Immediate response , battery exhausted ,charged both batteries ,but still no response, checked alignment of PAS sensor ,neon light remained dead, replaced sensor. As you surmised, there isn`t a display & power is regulated by speed & cuts out at c. 15.5mph. It is a simple system but suited me.

I don`t understand all the technicalities of ebike controllers. 2 contacts from the batteries disappear into the controller. Cable from controller to the motor contains 3 wires. 3wires from the PAS sensor also disappear into the controller. Inside the controller all components appear embeded in sealing wax. I repeat it is a simple system that suited my requirements.

I now suspect there is a fault in the Controller. The motor is 24v , battery 200WH, controller14amps programmed to deliver 250 w. Simple system--motor fires when you start peddling & stops when you stop peddlng. Can anyone recommend a controller i could use?

I've had a Revos motor for 3.5 years. had some problems but have been pleased with its assistance. Recently when cycling the motor stopped, assume battery flat. Checked with second fully charged battery but still no result. PAS no signal whether peddling forward or backward. Checked plug connection between controller and motor secure. Revos has ceased trading. I have tried emailing requesting details of components and wiring diagrams. No response though in the past were helpful. I have gained access to the controller in the base of the battery holder. No signs of a broken wire though it appears any components are sealed in what appears to be sealing wax. There is a capacitor and 4 spikes of wire protruding from the sealing wax. Dare I dissolve sealing wax to expose components? Thanks for any reply! Ron
