Can you post pics and give us a description of what you have done? I will assume you have the 120 volt power to the converter. Are you sure the polarity is correct from the output of the converter? Do you have 12 volts at the converter and not to the trailer?

It should be a rather simple matter to find your problem...

As TG mentioned...and, if the anser is NO to any of these steps, back up one step to resolve your problem...

1. do you have AC power to the new converter/charger?
2. with a digital volt-ohm meter, do you have POS & NEG 12 volt DC at the OUTPUT side of the converter - is the polarity correct?
3. do you have 12 volt DC at the input to the fuse panel?
4.have you checked the large amp fuses (or circuit breakers) that are in the fuse panel circuit to the battery cables?
5. check all fuses in the fuse panel for proper installation, blown fuses, etc...

In other words, start at the SOURCE and work your way through the wiring till you find where it isn't connected...

up and running, .was fairly simple even if your electrically challenged like myself. But it helps to have a friend who's a master electrician. Dinner and drinks did the trick. If anyone needs more info or help/ pictures contact me threw this site directly and i will try to be of assistance.
