Need some help here. Friend bought a Taxi a few weeks ago. Everything worked great for about a week. Then all 3 pop bumpers stopped working(slingshots are good). Giving a switch error on boot up but I do not think that is the issue. Lifted the play field and no power to the 3 pop bumpers. All other coils work and have power. Checked F3 on Aux power supply board and it is good(did not pull the board to check for cold solder joints will do that next time I get a chance to get over there) Giving a switch error on all 3 pops on boot up but I am thinking this has to be a power issue since there is no power to the coils(grounding using a jumper does not fire the coil and my fluke says .5 V). I am weak on system 11's so any help on trouble shooting is good. Since no power to the three pop bumpers have to think this is the issue even though the boot up complains about switches on all three pop bumpers. These are special sols on this machine. But let me know your thoughts.

Seems simple now that you pointed it out. Pulled the board, reflowed the solder joint, its all good now. Thanks.
