There was a modification on the M151A2 where a inline fuse was installed on the 467 wire to protect the flasher and components from such damage. The fuse was 5 amps. Details are located in CFTO C30-105-000/CF-008. 
 
If you cannot find the solid state flashers, a normal thermal flasher can be wired in place quite easily.  You have to cut off the 3 wire conector, and run the two wires to the prongs of a two prong flasher.  24 volt thermal flashers are commercially available. 
 
I have a number of the solid state flashers in storage somewhere, but it will be a while before I can get to them. The same flashers are still in use today, on the MLVW and the last of the M113s.
