Summary of change:
Subpage of MembersPage/Skassa Note that name of this page does not match conventions, should be MembersPage/Skassa/Trigger Anyway, keep trigger notes together, don't scatter to MembersPage/Skassa/Questions http://www.vems.hu/files/MembersPage/Skassa/trigger.JPG ---- http://www.vems.hu/files/MembersPage/Skassa/dizzy2.jpg This is a sample pic and not mine!. I have made the mistake to remove the tooth right before tdc and not 3 tooth before like on the pic, Can this be of any trouble? ---- '''Trigger problem''' noise when cranking * is like its missing some times, but only on cranking, in cranking datalog when runs at around 300rpm, but spikes to around 1800rpm, and that is what makes lots of trooble ** when its running, there is no problem Ignition on, rpm shows 0, then crank it, running around 300rpm, with the spikes to 1800rpm, then i stop cranking,but leave the ignition on the rpm will show 100rpm(must times); than the fuelpump stops, rpm reads 0 again * you can see that i use as much as i can on the TDC after trigger,that is becouse '''I removed the tooth''' just before TDC, so the angle is not ideal ** but if configured properly, this should NOT be a problem ** exact position ? The tooth _after_ the missing tooth is exactly at TDC than ? ** exact config ? '''Problem candidates''' * first of all, it's '''basically impossible to make a proper wheel by cutting down teeth'''. The signal waveform will be terrible at the missing tooth, causing all kinds of problems. Look at a factory Bosch 60-2 wheel to see that it's not just grinded off teeth. ** ElectronicDesign/SoundRecorder can confirm this ** in fact without this it's very hard to tell if * if you are lucky, it might just be reversed polarity VR (unlikely though). See InputTrigger/TriggerLog * I have put on a 20k pullup on the trigger wire, no change at all, * I have made lots of grounding to see if that could be the course, no change at all ** the problem is elsewhere, but you should do '''"proper grounding" instead of "lotsof grounding"''' ! See GenBoard/Manual/GroundConnections ** insufficient grounding (most likely VR- grounded at bad place, not near EC36pin26) results in trigger noise, that is most significant during cranking (and suppressed during normal operation) * the fuelpump switchon/off can trigger the VR inputtrigger when the engine is off (VR trigger sensitivity increases): this is normal. If grounding is properl, it won't effect normal operation since with running engine the input signal raises adaptive threshold that suppresses small 50..100mV noise. * Because when cranking,with the injector plugs of so it will not start. ** what ?
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
