speedo not working :)

ok, it would have to be a lack of power to the box - the red wire, or perhaps the white having a problem somewhere along its length - cant think of any other reason why speedo wouldnt work

 

also appeared to be that the engine management warning light came on - is it possible my speed sensor is a bit dead?

Dood mine did this after I jump started it. Spoke to pete and he said they do that sometimes. He said to send it back up to them to get it re-programmed. It started working again on its own accord after I had left the battery out of it for over a week. Coincidence??? I don't know. All you have to do is follow the wires that are coming off the thor box and check them to see if they are connected. If they all are check that the box is getting 12 volts with a multimeter. Then if you have access to gps or A nother person capable of 120 take the car out and see if it will go through the limiter. If it does it may be programming problems and the box may have to go back to thor.
