As title says, and I'm stuck:
> only the canopy bulbs out - customer started and bed and they were all out (all at once); facials, bench and shoulder working; bed runs as normal (timer, all fans, etc)
> canopy contactor contacts singed, swapped with bench contactor (same p/n), no change (bench bulbs still functioned) - will be ordering a new one anyway
> logic board: the D12/RUN LED is flashing rapidly about 9-10 times(almost like a strobe) , goes out, and repeats
> getting proper power to all 3 capacitors
> canopy connection plugs triple-checked, plugged in and secured

Bed info: Mod. # L-52STARB Date: March 2003

Ideas?

Do the lamps come on if you manually close the contactor? Did you check voltage of the contactor? Does the contactor actuate when you turn the timer on off?

> No, tried that, they do not come on by manually closing contactor (either one I tried in circuit) - Bench and Face do, though - as long as the timer is set
> I have proper voltage on both sides of contactor(s) contacts
> Yes, all contactors work (close) as they should when I start/stop the bed via the customer touch pad

Should note that I'm the only one who's worked on this bed in the last ~3 years; have previously replaced the face contactor, but it's coil was burnt...

Edit: should also note that the wiring connectors (stake-ons), or specifically the yellow or blue plastic 'insulation' on them, for this contactor (only) are scorched. The metal is not blackened; they have obviously been hot. I have good continuity through all the wires (contactor to capacitors)...

Since last post: Have relamped canopy and installed all new starters, as well (it was due) - still out
