do you not have some copper desoldering wire? run to radio shack and ghrab a roll $3-4.

lay it on the legs of the transitors, press your tip onto of it and heat that **** up, you'll mop all the solder right up like water with a sponge.



if you're never going to use low ohm injectors, you can skip building the pwm flyback circuit and jump R37 and R38.

hell, bridge the connections temporarily and see if that solves the communication issue.

You should have gotten a solder sucker. Its the single most important tool other then the iron when soldering.

it is Q14 and Q15. The problem is I have them out, but the little holes are still bridged even when there is no solder, I think I messed up the bord in that area. Im checking if they are bridged with an ohm meter, when they are bridged it reads 0 ohms.

Can I leave out Q14 and 15? I only plan to use high imp. injectors. What if the 3 little pads are still bridged?

I did and I tried, they still are bridged?

Ok, I bridged r37 and r38, when I plug he stim in the PMP light goes on for 2 sec then goes off. What does this mean?
