Thanks for the advise lads, It is actualy the needle that is moving left to right but this is intermitent. Ihave changed the gauge and checked the wiring but i still get the same problem! It is as if the voltage stabliser is faulty but this is contained within the gauge so it has to be ether another faulty gauge or the sender. The thing is if a sender goes down it just normaly reads incorrect but my gauge needle moves erraticaly, very strange? Mark |
