A: The amber light denotes an internal temp to high for normal. The charge unit then
reduces its output power until temperature is maintained. Ambient air over 85
degrees may cause the unit to be warmer than usual and is not a failure. In some
cases it may be required to check the charge algorithm and adjust as necessary.
Note: Contact manufacturer of the charger for specific information on what
algorithm to use with the battery choice you’ve made.
IX. Reset Alogorithm for Chargers
If the battery pack at any time is replaced, contact the manufacturer of your
charger (Delta Q or El Con) to obtain the correct algorithm setting to reset the charger
for the new battery pack purchased.
Listed below are steps to adjust the charger from a normal 215 amp/hour, flooded
lead-acid battery, to the US250 HC/XC battery with 283 amp hours.
1. How to Reset Algorithm for Delta Q Charger
Remove positive cables from the batteries- passenger side. (Big black cable with red
shrink wrap.) Also remove small 12 gauge-ish RED wire.
NOTE: Make sure you are near a charging receptacle. Vehicle must be plugged in for
procedure.
a. Locate LEDs on charger itself. Specifically looking for ¾ full battery. The battery
will flash current algorithm in system. If you have trouble getting to your charge
unit, you can also use the LED mounted on the body.
b. Once located, plug AC cord into car and into outlet as if charging. Lights on LED
will flash in sequence, letting you know current algorithm.
c. As soon as the ¾ full battery starts to flash on the charger, or the LED on the
body, place small 12 gauge-ish RED wire directly to the positive post and hold for
exactly 3 seconds.
d. Remove wire.
e. Now the ¾ battery LED on the charger or body should flash the next algorithm.
f. Repeat steps c and d until the battery LED flashes 7 times.
g. Once 7
th
algorithm is reached, hold the RED charge cable (12 gauge-ish wire) to
the positive post for 10 seconds. This saves the current algorithm. You will hear a
faint click coming from the charger and the bar graph LED will flash and start to
light up.
h. Unplug AC cord from car.
i. Unhook red cable from positive post.
j. Wait 10 seconds.
k. Hook positive cables back up to the battery.
l. Ensure correct torque is applied (70-90 inch pounds or 8-9 foot pounds).
