StingrayL82,

OK, that green color on the black wire connected to the bottom of the second fuse bothers me. This appears to be corrosion and that is bad. It will cause heat.

First turn off the shore power.

That corroded connector needs to be cut off and the wire cut back until you find clean wire with no corrosion. Then put on a new connector and clean up the screw and buss on the bottom of the second fuse, then reconnect the wire.

Turn the shore power back on for about 15 seconds, turn it off, then see if the connection is hot. I use an IR thermometer for this type of thing, but you can use a finger (carefully) in a pinch.


If it is still cool, try the power for 30 seconds and check again. If still cool, then turn on the refer for about 30 seconds and check again. If still cool, then try for 5 minutes. Note that refers on 12vdc draw a lot of power, so a little resistance can cause a lot of heat. Because they draw so much 12vdc power they are normally only used when driving so they don't kill the battery.

Do you have an electrical meter? If not, you should get one and keep it in the RV. You can get one at Harbor Freight for about $10.

Hi, hope you guys are all well, have not been here for abit. My 1978 Dodge Sportsman B300 440 ci. motorhome has a brake pedal that does not return. Need to pull it back with your toe to get the brake lights to turn off.
I removed the instrument cluster panel to access the pedal linkage area and lubed it up but to no avail.
Obviously there is not a spring to pull back the pedal that I see.
Any ideas? And the best way to troubleshot the cause so I can get the pedal to come back??
Thanks, really appreciate any assistance!

I don't think the converter is causing ang problems. Don't remove it yet.

Ok, that fuse panel looks way better than it did. And it seems to be working way better too. Is it still cool when the refer is on 12vdc?
