Dear Editor,
If your MLRS charging system isn
'
t doing
Not Charging? cH dIOde
the job and you±re running into dead launcher
batteries² the problem may be blown diodes.
Our normal troubleshooting tu³ed up
nothing wrong´ But then somebody thought
to check the four diodes in the CB1 boxµ They
were blown¶ Once they were replaced, we
±-²
were back in business´
Usually Just a look will tell you if any of the
diodes are blown´ Blown diodes have a
cha·red area in the center of the tube´
If you have doubts, test them with a multimeter¶ ¸f you find very high
or very low resistance and it±s the same resistance when you reverse
the probes¹ then the diode±s blownº
A
good diode will show the
opposite resistance-very low or very high»when the probes are
reversed´ Suppo¼t can replace the diode¶
