Look for places ** It seems you replaced C33 yourself, check if shorted there. ** Also see D27 (maybe shorted or reversed ?) ** and SJ7 at the bottom, almost under the FETs can be opened to see if the sectrig LM1815 pulls the signal to ground for some reason ** if you purchased bare board, and assembled yourself, this part was not tested with the mintest. So it is even possible there is a short somewhere on the PCB traces ** if you have problems to find the short, while the board is powered, you can use a 0.5 .. +5V strong supply (100mA or higher) to inject current into the short, and measure with DVM mV mode to locate the short. Don't use +12V (or anything higher than 5V), that would kill components. Be careful. If you have max +0.7V supply, or limit with a resistor and diode, you can do the measurements with the board unpowered. http://www.vems.hu/files/MembersPage/PeterJensen/trigger_test.jpg Measurements with exchange crank home trigger http://www.vems.hu/files/MembersPage/PeterJensen/s2/trigger_135_ref.JPG Measurements with exchange crank home trigger http://www.vems.hu/files/MembersPage/PeterJensen/s2/trigger_135_ref_1.jpg ---- Added a 20K resistor (12..15k is better, sometimes 20k is too high) http://www.vems.hu/files/MembersPage/PeterJensen/audi_trigger/trigger_1.jpg Soldered JP7 http://www.vems.hu/files/MembersPage/PeterJensen/audi_trigger/trigger_2.jpg Mounting the stepper chip http://www.vems.hu/files/MembersPage/PeterJensen/audi_trigger/trigger_3.jpg C103 replace with 1nF (only needed on certain boards from a given old batch, 2005 or so) http://www.vems.hu/files/MembersPage/PeterJensen/audi_trigger/trigger_4.jpg added 1uF cap in parallel with C40 http://www.vems.hu/files/MembersPage/PeterJensen/audi_trigger/trigger_5.jpg R182 shorted http://www.vems.hu/files/MembersPage/PeterJensen/audi_trigger/trigger_6.jpg Made wire for the crankhome-VR trigger input (EC18 pin 12) http://www.vems.hu/files/MembersPage/PeterJensen/audi_trigger/trigger_7.jpg Connected JP 2 and JP 7 so the primary trigger goes where it needs to: http://www.vems.hu/files/MembersPage/PeterJensen/audi_trigger/trigger_8.jpg
