Well ill be the first to start this on elb version 9.23487.

Just got an edge ultra with and LED traffic advisor.

Outboard strobes and t/a work fine.

All the other strobes dont. You can hear the power supply firing and the strobes are "snapping" however not lighting up.

Any ideas?

This is a serial controlled setup, right? How many strobes are in it?

Open the bar up...

Test #1

Take out and test the strobes that aren't firing [if you have a spare power supply] or connect them to the power supply that you know that works in the bar. And vice versa, take a working strobe and attach it to a nonworking power supply.

Test #2

[if serial controlled] at the main relay board, take the input harnesses to the power supplies [eight pin connector] and swap the working one with a nonworking one. See if a different power supply starts working. If it is serial controlled it could be a programming issue in the control head.

What is odd is that you hear power supplies/strobes firing but no light. Last time that happened to me, the strobe head was shot. How many strobes aren't working right? How many power supplies aren't working right?
