slm Posted January 14, 2009 Share Posted January 14, 2009 please can you help.looks like there's alot of knowledgeable people about. i require correct wiring for coil. its a rangie 3.5 efi standard 1987/88 automatic i have a white wire coming out of the loom on the inner wing which reads the same as battery 12.8 volts i have 2 wires coming from the disi amp 1 wire is white and black the 2nd wire is white. i have a black wire which comes from i believe a condenser clamped on coil mounting bolt. i have a blue and black wire which comes from a relay bolted on the bracket just under the airflow meter.what is relay for? finally i have a small black resistor about an inch long which has 2 male connector ends . at present the engine turns over but i have no spark from coil and no feed to fuel pump.fuel pump works with a direct feed from battery.i have checked fuses. i have tried a borrowed coil but get the same. just trying to make sure everything is correct before fitting a new coil to elliminate that part of the system. thankyou for your time and help.

FridgeFreezer Posted January 15, 2009 Share Posted January 15, 2009 The relay is a Land Rover bodge, it switches the coil signal to the ECU off (controlled by the vacuum switch on the back of the plenum) on over-run, which stops it injecting fuel when coasting. You can bypass it with no adverse effect. Quote Link to comment Share on other sites More sharing options...
steve_d Posted January 15, 2009 Share Posted January 15, 2009 White comes from ignition switch and goes to coil positive and dizzy (White). White/black from dizzy goes to coil negative. Resistor fits to the coil negative. Other end is white/blue and goes to over-run relay pin 30/51. White/black from over-run Relay pin 87 goes to ECU Pin 1. Condenser goes to coil positive. The fuel pump should be fed from the fuel pump relay which lives under the drivers seat in front of the ECU. This will be switched either by the ECU or if the air flow meter is open i.e. there is air flowing. Both these feeds come via the diode pack which lives beside the fuel pump relay. So in answer to your question the fuel pump will run whilst cranking or you can test it by holding the flapper open. Steve Quote Link to comment Share on other sites More sharing options...

leigh enfield Posted February 16, 2009 Share Posted February 16, 2009 Hi, I have a 2a 2.25 1964negative earth but not sure where the old brown wire, LT wire and ignition wire should connect to i.e. positive/negative on coil - any help would be much appreciated.
