kpretro84 Wrote:please some one tell me where these wires go and what they'reSince you asked nicely ![]() in the picture, sitting on my dining room table. It has a 4-pin green plug attached, and wires like so (reading from left to right... Red wire: either IGt or IGf and goes to green plug (from there to ECU) White wire: either IGt or IGf and goes to green plug (from there to ECU) Brown wire: Power supply, goes to coil +ve and then to green plug Yellow wire: Tacho output, goes to green plug Black wire: goes to coil -ve The IGt wire takes the trigger signal from the ECU to the igniter. The IGf signal is sent from the igniter to the ECU to let the ECU know that the igniter has fired. You need both connected for the engine to run. There should only be one wire on the coil negative, but there may be several on the coil positive, as that wire is often tapped to get a key switched supply for other purposes. Smoke from the wires means you have a short, or have found some other wire of passing a heavy current thru a thin wire ![]() If the engine struggles when the coil HT lead is connected to the dissy, it suggests that your timing is over advanced. Try retarding the distributor by turning it clockwise as far as it will go. Cheers... jondee86 |
