I car wiring harness chu a upa tawh em tih chu a hnuaia thil awmte en hian i hre thei ang.
A hmasa berin wire-te insulation chu uluk takin enfiah rawh. Insulation-a crack awm hian wiring harness a upa tawh mai thei tih a tilang chiang hle. Insulation pangngai hian a flexibility engemaw chen a nei a, mahse aged insulation chu a khauh a, a peel tan pawh a ni thei. I hnaih hunah rimtui lo i hriat chuan tar chhinchhiahna a nih theih avangin fimkhur rawh.
A dawtah chuan wiring harness connector chu enfiah leh rawh. Kum upa tawh connector te hi an lo loose a, an elasticity an hloh mai thei. Hei hian ignition nghet lo emaw, lirthei start harsa emaw pawh a thlen thei. Connector contact tha lo hian engine performance nasa takin a nghawng thei a ni.
Tin, engine bula wiring harness pawh ngaihtuah bawk ang che. Engine hian lumna nasa tak a siam a, a bula wiring harness te pawh hi hun rei tak chhung boruak sang tak a awm chuan a upa zawk. He hmun bula awm wiring harness te hi kum sawm vel hman a nih hnuah tar lam harsatna an tawk tlangpui. Engine lumna bul hnaia insulation-a crack emaw, inthlak danglam emaw i hmuh chuan tar theihna a sang hle.
Engine compartment chhunga wiring harness connector awmte mit hmuha enfiah a pawimawh hle. Rangkachak rawng inthlak danglamna ngaihven rawh; rawng pangngai lo chu tar chhinchhiahna a ni thei. Tin, crack, chhiatna, surface wear, corrosion, leh oxidation te pawh enfiah bawk ang che.
A lan dan bakah hian performance test pawh tih theih a ni. Entirnan, contact resistance leh value dik lo tehna hian connector a chhe thei tih a tilang a ni. Circuit conduction dik tak finfiah nan continuity test neih a ngai bawk. Parameter hrang hrang test hmanga connector dinhmun tehna atan pawh electrical parameter testing hi a pawimawh hle.
A tlangpuiin automotive wiring hi kum 10 vel a daih thin. Degradation hi kum nga vel hnuah a intan tlangpui a, degradation na zawk chu kum 10 vel a ni. Lirthei a upa poh leh engine compartment chu enfiah turin hawn fo tur a ni. Wire khuh tu insulating rubber crack emaw peeling emaw, bundled wire vel rubber tubing chhiat emaw te hi ngaihtuah tur a ni a, hengte hian wire a ti chhe chak thei a ni. Wire langsar apiang chu lirthei khalh himna atan thlak vat tur a ni.
