Is there a slow wake up procedure for whelen 9000 strobe bars that were not used for several years?

[busbart]

I have a few Whelen 9000 strobe bars around, and didn't use them for a long time (years)
A while back I tried one, and that had very odd things happening, in the way of flashing.
and I'm not sure anymore, But I thought someone mentioned that there is a sort of "wake up procedure" to get these bars going strong again?

Hi,
Here's a thread that might help:

Whelen Comander 5200 power supply

Hello, how can we tell if a power supply is toasted? When I put the power on it, there is a spark, but no life... Also, the power supply is almost 40 y.o. and sold as new. Is it true that it sat on a shelf for several years, it is basically dead? Thanks, Bernie, Montreal

Also be sure to use a proper battery or power supply, no jump packs

I've powered up a few 9000 bars that have been powered down for a LONG time and never had an issue.

well, in what way you did that? like discribed here before?

Sometimes the capacitors need conditioned. Letting the bar run, or charge up will often restore them. Also voltage, ground connections, and bulbs near failing can cause issues. U hook them straight ot known good power and run them for half an hour and see if the problems improve or worsen. Then i swap bulbs around to rule out bulbs.

I like to slowly turn the lights on in the room they're in, one by one, while singing you are my sunshine...


Oh wrong wake up procedure... Do what John M said

Ok, but I won't sing for them.... :-(
