Converter Power

Not best practice but legal . If the instructions (UL listing) of the converter require a 15 amp branch circuit over current device ,then you need to follow the converter's instuction sheet
May is the qualifying word.
I just can't imaging connecting a very critical, 5 amp max load converter to the 30-50 amp breaker on the power post and expect any sort of protection.

Wiring Diagram

By this many years and owners, hard telling what is wired to what in your U-Haul. I'd suggest tearing out everything and rewire from scratch. It's not that difficult on the 12 VDC side and the 120VAC side is fairly simple for an electrician to tie in.

You can start with almost any generic trailer wiring diagram.

Consider starting with a Progressive Dynamics PD-4045 power chassis. Less than $175 on-line, and it will take care of all your power needs for at least the next 50 years,

As Bob suggests previous owners may have messed with the wiring so you may be better off to redo it if your having issues. Having said that though you may also be lucky as I was and have a trailer that no one decide to reinvent the wheel on ;-)

In the Document's Center of this list (link on the right on the main list page) you will find electrical plans for several brands - including a fairly detailed one for Scamp. Take a look under the Burro to see if any of the manuals or what ever else has been uploaded has a wiring plan in it - even though it may not be filed under electrical.

Like others have said it's probably a long ways from original wiring. Don't be fooled by the fact you won't get shocked from 12 volts, it just as dangerous as 120 Volt if not done correctly. Many shade mechanics seem to think because you can't get shocked from 12 volts it's ok to mess with without the necessary knowledge. It's not. Many automobile fires are caused by electrical problems. Remember automobiles use 12 Volts DC too.

Standard thermal magnetic circuit breakers of any ampacity provide little or no protection for sensitive electronic equipment beyond possible short circuit protection .All the 15 amp circuit breaker basically does is provide a disconnecting means for the converter .
This is the reason that microwaves televisions ,computers ,converters and other sensitive electronic equipment have internal fast acting fuses. The 15 amp breakers in your house are there to protect your homes wiring and not to protect the equipment that is plugged into the wiring.

And in many cases "fast acting" can be quite slow. In my experience most semiconductor devices are faster Raz

Quite true : In some cases by the time the fuse opens up and clears the fault ,the damage has already been done.
Thanks Raz
