Ari Posted October 30, 2021 Report Share Posted October 30, 2021 Back again.... I've installed a 24/1 tooth dizzy in the car, I've even tried using the original 24/4 tooth dizzy with 3 teeth ground off on the top trigger wheel to see if that makes a difference. I'm currently getting no spark so I'm unable to set the base timing. I'm using a single chanel ignitor from NZEFI and a link map sensor as well. I'm sure that that just missed something obvious but for the life of me can't see what it is. I've noticed that I'm also clocking up a lot of trigger errors as well. Any advice/guidance/pointers would be much appreciated Thanks in advance TriggerScopeLog 31-10-22.llgx base map from link.pclx Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 31, 2021 Report Share Posted October 31, 2021 You've got a wiring issue by the looks, the same signal (looks like 24T) is coming through on both trig 1 and 2. From memory in the 4age distributor you have a yellow or white wire which is shared with both sensors, this should be connected to ground, then a red for trigger 1 and a green for trig 2, is this how you have it?

Ari Posted October 31, 2021 Author Report Share Posted October 31, 2021 Thanks Adam, a star as always. I had the signal and earth wires back to front. I've sorted that now (trigger scope attached) but I've still got no spark. I've tried the ignition test and my scope picks up that the coil -ve is clicking so my guess is that the wiring to the ignitor/coil is correct. I've also tried my spare coil and get the same result.

Adamw Posted October 31, 2021 Report Share Posted October 31, 2021 Yep scope looks happy now. I dont understand what you are saying about the ign test. So if you do an ignition 1 test on you dont get a spark coming out of the coil lead if you pull it out of the dizzy? Quote Link to comment Share on other sites More sharing options...

essb00 Posted October 31, 2021 Report Share Posted October 31, 2021 ...then you need need to check the wiring of your igniter/ignition coil. Quote Link to comment Share on other sites More sharing options...

Excuse the crap drawing but this is basically the wiring to the coil/ignitor Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 31, 2021 Report Share Posted October 31, 2021 Is it a J121 ignitor? The terminals should be marked IB, G & OC. IB connects to the ECU ign1. G is ground. OC is the coil negative. Is this how you have it? Quote Link to comment Share on other sites More sharing options...
essb00 Posted November 1, 2021 Report Share Posted November 1, 2021 If you have it connected with that diagram, then you're missing +12V on the igniter... The body of the igniter is to Gnd. Check the diagram below (you don't need to connect Igf). Quote Link to comment Share on other sites More sharing options...

The body of the igniter is to Gnd. Check the diagram below (you don't need to connect Igf). Im not using the stock ignitor. This ignitor has 3 wires, it gets its 12v from the -ve side of the coil and has a separate earth to the engine block. Check both my coils at work and both failed so seems like that was my issue. Checked wiring to ignitor as Adamw had said all good. Thanks for the help Quote Link to comment Share on other sites More sharing options...
essb00 Posted November 2, 2021 Report Share Posted November 2, 2021 Oh, sorry I didn't see you're using another type of igniter... Quote Link to comment Share on other sites More sharing options...
