I went dumpster diving again last weekend just outside of one of KSC's ground support firms and fished out this spotlight, which sports two axial fiament lamps and a whopping 7" reflector
Collins Dynamics, Gen-56
Water logged, but generally intact. The head appeared dry. Whatever sort of solution it was dumped in, it sure smelled like the dumpster behind KFCs. A good rinse with some soap took the stench right off. With some research, it was one of these: http://www.havis.com/products/SPTLT_...19210-932.html
Rechargeable? You bet
There was a 3 stage switch on the handle, much of the outside was intact. The reflector alone was a beauty, completely dry and no blemishes, whatever that was flakey was on its window.
not sure if you can see it, but there is two lamps in the reflector, one on top of another. Both Axial filament
It used a 6.5AH SLA, no surprise, but the battery bay was partially flooded. With the battery on its side, the positive terminal was so corroded it broke off the battery when I tried to take it out.
A look under the handle and lid I see a voltage comparator circuit using an heatsinked LM317 along with a TO-220 FET
4 wires, green white white red, goes up to the lamp.
Looking into the battery bay, the positive terminal had two wires, a red and a blue. the negative contact was not affected.
The thing weighed about 15 pounds when I found it, now its washed, dried, and gutted its like 3 pounds. The charging pin out is unknown, but has 4 contacts.
Anyone think I should try and restore it? Or should I try the other dumpster thats filled with partially cut aluminum, aluminum strips, aluminum shavings, and funny looking blocks of aluminum to see if theres anything usable
They do sell a charger, but its $40
Its on the shelf, earliest I can get to it will be after I get back from New York, which is in the middle of June.
