Anti collision lights dead!

Hi everyone, 

just finishing up my annual on my ELSA AMD built 601XLB

when I tested my lights I found my Aeroflash Strobes not operating 

spent a couple of hours troubleshooting to no avail. I found Juice at the switch, tried to follow the wiring to

the strobes. Cannot find any issue. Wires are really buried and mostly inaccessible.

i figured I must of pulled a connection loose during the annual. This unit uses two wing mounted power supplies so I would think if it’s a bulb or power supply one would still work.

i had to walk away and look at it again tomorrow .

Any body out there have a similar problem? Or any suggestions?

thanks Dave

    To possibly state the obvious - did you check the grounds at both lights? Many times these are grounded at the wing tip rather than running ground wires back to the firewall. Though of this were the case, you'd think one would work. 

    Did builder install an inline fuse downstream of the switch? Its not a good idea, but it happens.
