i do believe you have burnt out the inverter within the system :( i dont have an answer for you on how to persue a fix but i do wish you good luck .......keep in mind these are very cheap new nowadays so dont pay a big amount to fix it if possible ok :)

check the voltage and current rating mah for the battery there is a probability that the battery may be of high current rating and your charger of low so it will definetely not charge the battery of the camera or will take too long to charge it..

The charger has four distinct charging stages - 1) Bulk, 2) Acceptance, 3) Float, and 4) Equalization. If your batteries are old and therefore won't reach full charge, the charger may not be able to get them up to the voltage where float charging kicks in. If you ever allowed the water in the batteries to get down to where the plates were exposed, one or more of your batteries may be contaminated with excessive sulfate buildup on the plates. The equalization process (Stage 4,which must be entered manually) will help to return any excessive sulfate builup back into solution, so you might try that and see if the performance improves.

you have to let the battery charge for 12 hres minimun, after that if you dont have power in the battery try another charger to see if it works if yes
replace the battery . or you can replace both...
try this fist....
hope that will help you

Fis\rst of all is the inverter supplying 120 VAC? when turned on?. If so the inverter seems to be working.I think your problem is in the truck alternator/charging system. The inverter is independent of this charger..

is the bateries draining quikly?, if so try redusing the load on the inverter ,always make sure it is fully charged before use.

check if the inverter has a fuse for the charger, if it does test it if it is still ok if not change it
