“SHUNT” (selecting “CLASC” uses the Classic’s internal shunt instead). Press
Enter to save your choice.
Setting the Ending Amps value properly is important. Setting this value too
high will lead to under-charged batteries. Setting it too low may make it
impossible to reach. In which case, the Classic will transition to Float based
on Absorb time. Similarly, an Ending Amps setting of “<0.0” will disable this
feature, causing the Classic to transition to Float based on Absorb time only.
Consult your battery manufacturer’s literature to determine recommended Ending
Amps.
Note: If you have two or more Classics connected using Follow-Me mode, the
other Classics should follow the Classic connected to the Whizbang Jr.
TROUBLESHOOTING:
If the Classic’s Whizbang Jr. status screen (see Fig. 4) shows the Whizbang
Jr.’s board temperature sitting at -50°C after initial setup, then the Whizbang
Junior is NOT communicating with the Classic’s AUX-2 circuitry. Here are some
tips in troubleshooting this scenario.
Is the Classic firmware up to date? Check the Classic’s status display
for main firmware/MNGP firmware versions.
Does the Whizbang Jr’s purple wire make a solid connection with the
Classic AUX2+ input?
Is the Whizbang Jr. securely attached to the shunt?
Is the shunt attached to battery-negative? Is the Classic tied to
battery-negative?
Is the Classic’s AUX-2 setup mode set to “WHIZBANG JR.”?
Check the Whizbang Jr.’s LED

Note: To manually reset accumulated Whizbang Jr. Amp-hour tallies, go to “LOGS”
menu and press Enter. There are three entries related to the Whizbang Jr.: “WB
Jr. NET Amp-Hours”, “WB Jr. (+AH)”, and “WB Jr. (-AH)”. To erase, select one
and use the soft-left or soft-right keys to confirm “YES”, or “NO”. Once
confirmed, the Classic will display “Clearing Data” for a few seconds and then
return to the main log menu.
