Explosive Ordnance Disposal…
Getting Wires
Uncrossed
During maintenance
on the explosive
ordnance disposal
body (BEOD), the
wires for the 12
vdc (it looks like
a cigarette
lighter) and the 24
vdc output some-
times get crossed.
“Then when you plug a component in the
‘lighter’ you get 24 vdc
instead
of 12
and the component can be damaged.”
“There are two places the wires
get crossed: at the circuit
breaker under the radio speaker
or at the batteries.”
“At the circuit breaker, the #1
7
wire should go to the 12 vdc
breaker and the #10 to the 24
vdc. See the wiring schematics
drawing in the commercial manual
that came with your beod.”
“At the batteries, the #1
7
wire should be
attached to the positive terminal of the 12
vdc battery (the one on the left) and the
#10 to the positive terminal of the 24 vdc
battery. if they're
not
, reconnect them.”
“So before
you use
the BEOD
again,
check the
wires to
the 12 and
24 vdc
outputs.”
roger
that
one!
if the rear electrical
outlet is putting out
24 vdc instead of 12,
there could be a
short in the inverter.
whoa!
1.
Disconnect batteries to prevent damage or injury.
2.
Disconnect the #17 and #10 wires.
3.
Connect the #17 wire to the 12 VDC breaker.
4.
Connect the #10 wire to the 24 VDC breaker.
uh-oh.
I think
somebody
crossed
my wires!
if the wires
are
crossed,
uncross them
like this…
The manufacturer's
address and phone
number are listed in
the beod commercial
manual.
Check the voltage
with a multimeter. if
the inverter is bad
and is still under war-
ranty, contact the
manufacturer about a
replacement.
