Default Re: HFS-3 thres problem

Ok so pin 17 has no voltage what so ever. The board blew on two spots as clearly show on the picture. The 310 resistor was completely burnt I replaced it with a 470 though maybe that was the issue but after getting the correct resistor there was not change in the controllers behavior. Thought maybe it was the IC that it goes to so I replaced that as well (will not give the part number over the open forum will PM you the part number I used if you need) and still have absolutely no change in the controllers behavior. The other place it burn is where you change between a positive and negative pwm input I made sure that there where no tracks off(the positive pwm track is off didn't bother repairing it as nothing will be going to that track). Please excuse the red and black cables soldered to the board its just so I can test it on my workbench. The Aquamist system is connected to my nissan 200sx running a haltech ecu with a negative signal going to the controller. Appreciate the help thus far.
