Hello to all. I would like some information on troubleshooting an SVD with some strange issues. I would like to let everyone know that this is my fourth SVD in 3 months. I have not mistreated them in any fashion except for one of them which I replaced at my own expense. My problem is this. All of them have developed firing button issues related to sensitivity loss or non-function. I have seen multiple threads similar to this but I also get one symptom that I have not seen in any other thread. On the one that still works, when I fire it, occasionally it flashes the fire button green a number of times (not sure how many, not looking right at it when it starts) and goes dark. The mod is still on and will respond to the + and - buttons and the fire button continues to operate. I have had it with the SVDs and their unreliability. They came recommended from multiple people who continue to use theirs. 3 of mine have been real SVDs and one was an FT clone. I currently have the clone and the latest real one. The clone and the other stopped working at about the same time (within a day). The 'real' one continues to work, albeit not reliably whereas the clone is just dead. This all relates to the fire button. I just want a stick that works and I can't seem to find one. I run one with the aqua dual coil (1.1 Ohms) and the other with a kayfun Lite (1.9 Ohms). Swapping RBAs and freshly charged batts do nothing for this problem. Help me Obi-wan Kenobi, you're my only hope.
