I picked up a LW3 with a few problem I have been working through. One that has me stumped is that the topper beacon spins continuously from the second it's powered on. I changed Q25, which I believe controls the beacon, because it tested bad. I thought that would fix it but it didn't. The pre-driver tests fine, so I am not sure where to go from here. I guess it could be a TTL chip or PIA? Anybody have this problem before or know how to fix it?
Also, it had a pop bumper stuck on and melted the coil. I replaced the coil and the Q9 and the pre-driver which is a 2N4401. I did not have a 2N4401 so I used a 2N2222A because I read somewhere they were compatible. Well the PB coil does not lock on now but it will not fire at all. Do you think the sub transistor I used would be the problem?
