Symptom
Solution
Not combining
Check Voltages at the
Power Terminal Block.
If
the Voltage
#1 - MAIN POS (+)
and
#3 - COM
NEG (-)
or
#2 - AUX POS (+)
and
#3 - COM
NEG (-)
are above the connect Voltage and the
difference between them is less the 10 VDC the
ME-SBC
TM
may be defective. Please call Magnum
(425) 353-8833.
No indicators
Check Voltages at the
Power Terminal Block.
If
the Voltage
#1 - MAIN POS (+)
and
#3 - COM
NEG (-)
or
#2 - AUX POS (+)
and
#3 - COM
NEG (-)
.
The Voltage between 1 and 3 or 1 and 2
must be more than 5VDC.
Not Disconnecting
ME-SBC
TM
does not disconnect. Remove the fuse
at both batteries and check resistance at
#1
- MAIN POS (+)
and
#2 - AUX POS (+)
on the
ME-SBC
TM
. There should be about 600k Ohms (
Ω
).
If there isn’t the ME-SBC
TM
might be defective.
Please call Magnum (425) 353-8833
Auto Reconnecting
every 10 Sec
If the Voltage requirements are satis
fi
ed and
this cycling occurs, then the Current sensing
is corrupt or the Current exceeds continuous
capabilities. Wait for the charger to go into Float
Mode and check status again. If the ME-SBC
TM
is
still toggling it may be defective, otherwise it’s
probably operating normally and protecting itself.
Adjustments are
unresponsive
Turn the knobs fully counterclockwise until they
stop and then adjust up to the setting. If they
don’t stop or don’t move call Magnum.
