Troubleshooting - Model 36271
NOTE: YOU MUST ALWAYS START WITH
FULLY CHARGED BATTERIES BEFORE
DETERMINING IF THERE IS A PROBLEM.
We use the word “Indicator” to mean the vari-
ous LEDs (Light Emitting Diodes) showing the
various faults, modes, and conditions of the
battery and / or charger.
The words “unit”, “charger” or “recharger”
means your model 36271 BatteryMINDer
Problem:
Battery Connect indicator does not light
Solution
:
Check electrical outlet. If controlled by a wall switch
be sure switch is on and try to prevent accidental
shutting it off while charger is working.
Problem
:
ERROR indicator lights
RED
(several possibilities can be the cause)
Solution
:
1. Output leads - connections to battery may be
reversed. Switch (reverse) connections at battery
2. If still remains
RED
check battery system volt-
age. If 33-Volts or less, one or more batteries
may be damaged and should not be recharged. If
batteries were just recently removed from a load
(headlights, door lights, etc. or vehicle was not
used for extended time without a maintenance-
charger, allow batteries to “recover” by letting them
“rest” without a load. If battery system is healthy
and just deeply discharged it should recover volt-
age (rise above 33 volts) sufficient to allow charger
to begin an attempt to fully recharge them. If after
batteries have “rested” (see pg. 9) they may not
be able to be recovered – recharged. Replace
ALL
batteries.
Problem
:
ERROR Indicator lights
RED
and is
blinking
,
Solution
:
1. Batteries may be weak or very heavily sulfated.
Allow batteries to remain in Maintenance-Float
mode for 72 hours or more and then attempt to
recharge again. 2. Batteries may be so large it may
require a second full recharge. Repeat recharge
by pressing and holding START/RESET/STOP for
5 sec. until ALL LEDs light. Reset battery type, if
needed.
