Check the battery voltage, nominal value > 125 V, possibly charge bat-
tery.
•
Check fuse F5 on D982 (battery block output).
•
Check fuse F3 on D982 (charger 1).

Check fuse F4 on D982 (charger 2).
•
Check the cable connection between the battery blocks and D982.
•
Check the cable/contacts between the individual batteries.
