If the operating telltale of retarder is gone out (should make sure the bulb is eligible and cable connection is correct), . the retarder is not available, check according to above mentioned. If the checking items are up to par, enter the next procedure. 如靜態(tài)和動(dòng)態(tài)下的檢測(cè)都正常，則可結(jié)束電氣部分的檢測(cè)。 If not, replace the control power switch. If the test lamp is illuminating but the corresponding retarder operating telltale or braking telltale of vehicle is gone out, check correlative circuits or replace the teltale. pressure switch注意：在進(jìn)行本檢測(cè)之前，必須確認(rèn)車輛的剎車氣路工作正常。 如果檢查結(jié)果與上述規(guī)律不符，則應(yīng)檢查手動(dòng)開關(guān)與緩速器控制電源開關(guān)之間的線束是否有斷路、搭鐵與線束之間因絕緣損壞相互連通的故障；若檢查結(jié)果正常，則進(jìn)一步檢查緩速器控制電源開關(guān)內(nèi)部的故障，具體請(qǐng)閱讀后面的介紹。如檢測(cè)1檔的輸出端時(shí)試燈不亮，則檢測(cè)手動(dòng)開關(guān)的電流輸入端是否有電以及5A保險(xiǎn)絲是否燒斷。If the cables cross over two ponents which have relative displacement, some margin must be left in case that the relative displacement produced by vehicle riding leads to pull apart the cable.㈥．安裝緩速器電源總線Power wiring harness of retarder (code “d” in Diagram2)1. 安裝位置 Installation site連接于原車+24V蓄電池和緩速器電源總開關(guān)、和控制電源開關(guān)之間。The main switch of battery should be shut down before installation. ㈡ 安裝緩速器控制電源開關(guān)Control power switch(VDHDK202) of retarder1. 安裝位置 Installation site、防塵且靠緩速器主機(jī)附近的位置；The installation site needs to be waterproof, dustproof, and keep it near battery and retarder.
