Issue: On Monster Bash, all flashers are really bright and fail after a couple of flashes. Furthermore, after 10 minutes of running, smoke comes out of the backbox and C10 on the PDB explodes.
Solution: Checked for voltage on flasher sockets and found +50v instead of +25v. The cap in the 25v section is rated for 35v, therefore exploding when prolonged 50v were applied to it. Found that a previous owner attached the power wire for flashlamps to 50v instead of 25v.
Cleaned exploded Cap, replaced C10, and connected flashlamps to the proper 25v power wire. Issue resolved.
