I guess I'll join this club now too! I got my restored High Speed 2 a couple of months ago.I have an extra Kenwood Stereo System in my game room and hooked it up to that.....WOW!!....I did not notice that the 5 flashers in the back box were not working until a few days after I had it. And I can not figure out just what the problem is? I tried putting in LED flashers....but they would blow out! Strange....And I am using the kind! So for now...no workie...Also I tried to hook up the Blue flasher mod...but it freaks the game out when activated so its left unhooked for now. Must be a wire shorting....or a bad transistor somewhere??
