[Milsurplus] Manual or schematic needed...

Fri, 6 Dec 2002 04:45:01 -0600

Ken,

I have a photocopy of TM 11-2646A which I could copy for cost.  A
couple of pages weren't done right and unfortunately among them are
the schematic and pictorial wiring diagram.  Some info is missing
from each.  The 'Theory' chapter has simplified schematics for
each circuit so perhaps there is enough there to get by.

Maybe someone else on the list has a better original?

Checking the ETM site (http://www.logsa.army.mil/etms/find_etm.cfm)
shows only TM 11-6625-317-24P which won't be much help.

Sometimes a 'not working' tag is a ruse to get rid of older gear.
I've seen stuff green tagged that simply had the fuse caps removed.
