Hi, I have a 95 ep82. I took the speedo cluster out to replace one of the bulbs. Since then my speedo has stopped working. I've disconnected the cable from the gearbox end and pushed it in, I've had someone holding it in while I plug it into the cluster, I don't know what else to do. When I pushed it in from the gearbox end the first couple of times, it works upto 5km/h and then drops back down to 0. Is there a trick I'm supposed to do?
