ya, an it has, strange though since the IC controlling it is the 16f6886, however the chip that blew was the 18f controlling it, which is totally isolated except the data wires, i wont waste much time there, but i presume its just cos the 18f is lower voltage
as for the coil it was hard to read, but im guessing about 0.5ohms-2ohms, its hard to tell since i had to subtract from the few ohm resistance from my test leads. however the inductance measures @ 0.05mH. also i wonder if i get a bigger coil, will it pull better (with more turns and less amps?), its already not very powerful,
now i know that gives a starting current of 300/0.5 150-600amps, but i also know thats inital, and that it decays fast, so even though that scr is 40 amp, i know it can take more if its a small enough pulse, but thats all i know and dont know how to get a "burst current rating"
also im sure that it is not a holding current stopping it since even after the scr has been disconnected and reconnected it does not unlatch, i even tried disconnecting it from caps and putting a -9v on the gate.
originally i thought of a scr as a high power transistor, but since using it and hearing that little click inside of it, i now think of it as more of a relay, weather this is right or not.
oh, an im not too sure, but i dont think im using or understand "charge resistor", i am using 16F with transistor to drive a boost converter, @ 12v1.5amps here is the thread:

and this is the closest schematic i can find for my converter:

, either way, the charger pumps the volts to the HV caps, isolated by diode so no back fire, and the HV caps are connected direct to the coil rite now
