scottly 475 Posted June 5, 2013 hey guys, in the engine bay of my ford xd ute the 2 ignition coil wires red light green (positive) and pink blue (neg) on the factory wiring loom I am having trouble with the voltage not sure if this is normal the guy from ice ignition recons I should have 12v plus at the coil. when I put the pos multimeter wire to the pos coil wire and neg multimeter wire the neg coil wire its reading 7.6v it should be over 12v yeah? but when I leave the multimeter pos to the coil pos wire and I move the multimeter neg wire on to various earthed parts of the car it reads 12.9v? my xd was originally a 6 cylinder now a Cleveland and the ignition is a ice 7amp 2 step kit any help or advice would be fantastic I am trying to sort out the the small problems threw winter on my xd project ute whilst I can not do paint and panel work thanks scott Share this post Link to post Share on other sites

Gaz 1,085 Posted June 5, 2013 XD 6cyl has a resistor wire to the coil. Fuck that off and run a new wire. 1 Thom reacted to this Share this post Link to post Share on other sites
scottly 475 Posted June 6, 2013 Yep that sounds right. What's the problems<br /><br /> the guy from ice said the coil should read over 12v the car runs but takes bit to get started. if it does not get a full 12v will my motor lack spark I dont know what is wright or wrong I also don't want to fry my coil. gaz the coil only has the the positive and negative going to it from the factory wiring loom and a positive and negative going to the coil for the ice ignition module. thanks for the replys any other ideas or information on this?

Tyler06 266 Posted June 6, 2013 Testing from positive to negative of the coil will not read correctly! Testing the positive to any other earth will. Share this post Link to post Share on other sites
Tyler06 266 Posted June 6, 2013 XD 6cyl has a resistor wire to the coil. Fuck that off and run a new wire. If its anything lime a corty gaz is definately right!! Run a new ignition feed to the positive of the coil and see how you go mate because it may be red/green on the coil but in the harness it may be a jelly type resisted wire which will only supply 9v and i found this out by stripping my harness and asked my mate who told me wat it was. It caused me all sorts of dramas... Share this post Link to post Share on other sites

xd4.1efisc 34 Posted June 6, 2013 The resistor wire is only on XDs that had points ignition (Cast iron 6cyl). Alloy Heads and V8s had electronic igition and no resistor wire. Share this post Link to post Share on other sites

scottly 475 Posted June 6, 2013 The resistor wire is only on XDs that had points ignition (Cast iron 6cyl). Alloy Heads and V8s had electronic igition and no resistor wire. Hmmm.. My ute was a factory alloy head crossflow. I'm away for the long weekend I will have to have another look when I get home thanks for that great info mate Share this post Link to post Share on other sites
xd4.1efisc 34 Posted June 7, 2013 Good info mate as per usual! Off topic is you car on the road yet? Chris, Its on the road but no boost, took the m90 off, and not far from putting the m112 in its place, might be done in the next few weeks, just came inside after doing a bit on it. I cut the engine bay off my XF van that was rear ended, and have set the m112 up in there so I can still drive the yellow one. Share this post Link to post Share on other sites

Thats awesome news dude so u gonna come next weekend for the OzFalcon cruise? Would love to pick your brains on how to correctly set up the map sensor function on the corty and catch up its been a while. Share this post Link to post Share on other sites
SJG351 6 Posted June 10, 2013 If you are able to fit a late model altenator as well that will give you around 14v when the engine is running, much better Share this post Link to post Share on other sites
scottly 475 Posted June 12, 2013 thanks guys for all the replys there was no voltage problem it turns out i was the goon who had no idea on end of the multimeter, tyler you are very right pos coil to neg coil gives a incorrect reading but pos coil to any earth on the car reads 13.9 witch is correct lol thanks again Share this post Link to post Share on other sites
