titikaka Posted June 19, 2009 Share Posted June 19, 2009 Hi all, I bought a Suburu EA-71 engine in order to replace a Rotax in a ultra light airplane ( ballerit HM 1000) The ignition coil was missing, I bought one from another subaru vendor. The problem is that there is no spark at the ignition coil output. I maybe made a wrong connection but I don't find any wiring diagram. My hall sensor has to wires : yellow and Black/white. Ignition coil has to pi : + and - I have connected Sensor: sensor yellow <--> battery + sensor black&white <-> coil + coil - <---> ground = battery - I am wondering now if there is any control unit between coil and sensor.. Does anybody can help ?? Thanks a lot if any idea I will bought a repairing manual but not sure to find this diagram inside... Quote Link to comment Share on other sites More sharing options...
4x4_Welder Posted June 20, 2009 Share Posted June 20, 2009 The negative side of the coil is switched. Connect the positive side of the coil to the ignition switch, and the negative side to the distributor. Quote Link to comment Share on other sites More sharing options...
titikaka Posted June 20, 2009 Author Share Posted June 20, 2009 Thanks a lot! Hope the engine will start now..! I discovered pinout connections of the sensor/ignition module : but they are exactly inverted...an idea of the good one ? http://www.mobiletron.com.tw/detail_main.asp?ID=978 http://www.nbhuaao.com/en/proview.asp?P_ID=1022 It seems also that we can find the same module in Honda civic 1300 from 1980 to 1983 http://www.hondapartsnow.com/Page_Product/PartDetail.aspx?catalogID=22&productID=4&yearID=13&doorID=2&gradeID=56&areaID=3&transmissionID=3&originID=-1&colorLabelIDs=-1&colorLabelID=-1§ionID=1&idAndImageID=3844%20457257&refNo=12&isBigPicture=False&pageName=&appid=4190 And I guess in other car : Nissan but don't know which one ..

Cougar Posted June 20, 2009 Share Posted June 20, 2009 You should have power on the blk/wht wire, if not check your fuses. This comes from the ignition switch and ties to the plus side of the coil. The yellow wire goes to the angle sensor and ties to the minus side of the coil. Quote Link to comment Share on other sites More sharing options...
titikaka Posted June 20, 2009 Author Share Posted June 20, 2009 Cougar, you are perfectly right Cougar! I did exactly the reverse connection... Following your information : now it is working perfectly : almost 2 cm spark turning slowly delco by hand! Just have to put back in the engine and it should start!! So here is what I did to make it work : 1) This is the Sensor/Ignition Module with 2 pins : Coil (yellow), +12v (black/white) ------ / | | |_____ | Coil ) | O ) | + _____) \ | \ | ------- I connect Coil (yellow) to Minus (-) of ignition coil I connect + of sensor (black/white) to +12v I connect + of ignition coil to +12v Its seems so easy now, but I didn't even know if a intermediate module was missing or not since I got the engine without the car So http://www.mobiletron.com.tw/detail_main.asp?ID=978 is wrong for me but http://www.nbhuaao.com/en/proview.asp?P_ID=1022 is ok In order to help people with broken ignition module (but it seems to be very strong since I made reverse connection and bad wiring, and still alive now!) Following the last url : the list of cars with such a module : GM AstraLB 1.5 1984-1986 AstraLC 1.6 1986-1987 GMTRUCKS 1982-1985 Others1.9L Eng.
