Introduction: Water lukewarm table is common breakdown is: Put through ignition switch, finger of water lukewarm table always shows in 100 ℃ above is not moved, the finger when water lukewarm change does not move subsequently; Put through finger of lukewarm table of ignition switch, water moves to be in to 40 ℃ , engine temperature is elevatory, watch needle is not mobile however. The breakdown reason of lukewarm table of project machine water reachs processing: Water lukewarm table is common breakdown is: Put through ignition switch, finger of water lukewarm table always shows in 100 ℃ above is not moved, the finger when water lukewarm change does not move subsequently; Put through finger of lukewarm table of ignition switch, water moves to be in to 40 ℃ , engine temperature is elevatory, watch needle is not mobile however. Breakdown reason is: Power supply cord opens circuit; Coil of the electric heat that express a head breaks a string; Coil of electric heat of water lukewarm sensor breaks bolt of line, wiring to become loose, the lead that express a head breaks Wen Chuangan of line, in-house short circuit, water implement invalidation; Invalidation of water lukewarm table, water lukewarm table takes iron to sensor lead somewhere. Eliminating a method is, examine ammeter (contact breaker contact must close) , if ammeter directive is 0. Make clear column of wiring of power source of switch of accumulator solstice fire a paragraph of public circuit opens circuit; If ammeter shows discharge is 5A about, express public circuit electrify, and come in column of wiring of ignition switch Ⅱ water lukewarm table and sensor this paragraph of circuitry opens circuit. Can enter igneous wiring column to build iron to try fire with water lukewarm table. With screwdriver mid rely on water lukewarm table closely to take igneous wiring post, make screwdriver needle delimits meet machine metal part, if do not have scintilla to appear, represent ignition switch to water lukewarm table one Duanlian line is broken. When building iron to try fire if scintilla appears, reoccupy screwdriver makes column of wiring of water lukewarm sensor takes iron, if water is warm,quickly roll reachs watch hand 40 ℃ position, prove water lukewarm sensor damages. Finger of water lukewarm table always points to in 40 ℃ breakdown eliminating a method is, close ignition switch, finger of water lukewarm table is turned quickly by the position of 100 ℃ above be in to 40 ℃ . After engine temperature is elevatory, finger of water lukewarm table still points to in 40 ℃ , express water lukewarm table to water a paragraph of circuit have lukewarm sensor breakdown. Can demolish wiring of water lukewarm sensor undertake opening circuit experimenting. If finger of water lukewarm table turns,answer position of 100 ℃ above, prove interior of water lukewarm sensor takes iron. CNC Milling
