Citroen Xantia

1. For check of the battery include head headlights. If some seconds later brightness of a luminescence of headlights goes down, therefore, the battery is discharged and demands additional charge or replacement (see. Check of a condition and battery charging). If brightness of a luminescence of headlights does not change, turn the ignition key. If now brightness of a luminescence falls, means, the current reaches the electromotor and the starter is faulty actually. If brightness of headlights on former remains invariable and thus is not audible click of operation of the traction relay malfunction actually the relay or its electric contour (see below), therefore, takes place. If the starter rotates too slowly, and level of a charge of the battery is in norm, or malfunction actually a starter takes place, or resistance on any site of a chain is excessively increased.
2. In the presence of suspicions on malfunction in an electric chain, disconnect from the battery all wires (including the grounding tire on a body). Also disconnect electroconducting from a starter / the traction relay and the tire of grounding of the power unit. Carefully smooth out contact plugs, then restore initial connection of wires and by means of the voltmeter or a lamp sampler make sure available full tension on the plug of connection of a positive wire of the battery to the traction relay. Make sure of serviceability of grounding. In order to avoid development of corrosion grease terminal connections of poles of the battery by acid-free vaseline. Remember that corrosion is the most frequent cause of infringement of quality of electric connections.
3. If the condition of the battery and all electric connections is found serviceable, check a contour condition. Disconnect a wire from the knife plug of the traction relay of a starter. Connect the voltmeter between the end of a wire and well earthed point (for example, the negative plug of the battery) and make sure available a food of a chain at the ignition key turned in the situation START. If a food moves regularly, therefore, a chain as it should be. In the absence of tension check a chain condition (address to Head Onboard electric equipment).
4. Check of contact connections of the traction relay can be made by a way of connection of the voltmeter or a lamp sampler between the food plug from the party of the relay turned to a starter and weight. At the ignition key turned in the situation START tension should take place. Otherwise the traction relay is subject to replacement.
5. If the condition of an electric chain and the traction relay is found serviceable, the cause of failure can be covered in failure of the electromotor of a starter and further check lies outside the limits of qualification of the average amateur mechanic. Before addressing for the help to experts carry out small marketing, having compared the prices for accessories to cost of the new or restored block.
