More electrical woes...

My trailer is refusing to run anything off the battery. I think that this is the culprit:

The old fuse on the cable looks done in. Is there something more modern that I should replace this with? I'm really not liking the old glass fuse thing any more. It keeps getting damp despite all efforts to keep it covered.

I don't think I have ever see a fuse mounted like that. Usually there is a circuit breaker inside the coach that looks like this.



You can get one here, on sale for $3.95. (30 amp)

Circuit Breakers for Your RV and Automotive Needs - PPL Motor Homes

I have seen a fuse block mounted at the battery terminal but can't find a picture of one at the moment.

Drat. This thing IS the source of all my trouble. I wiggled the cable and fuse around this morning, and have just returned home to an icy cold camper fridge and all lights working. I had left the shore power on for the day to see what would happen, and everything works right now. I have 13.9 volts at the battery. Upon unplugging from shore power and turning on the light over the sink, I had 13.7 volts in the battery. Everything seems to work correctly, as long as the fuse in the cable gets wiggled just right. This thing really needs a replacement.

I've seen fuses mounted like this before, but never this type of fuse. I'll do a little more research and see what I can find out about this.

Thanks for the circuit breaker, Gene. I may go with that.

It is good to hear that you found out where the trouble is.

One trick that works for me on almost every electricical connection is WD40. Spray the contacts and reconnect the wires or fuse. It even worked on a particularly troublesome circuit board edge connector on an old computer I had.

Unless my eyes are deceiving me, that looks like an older home type screw in fuse. It looks like Tron TL 30 on it....

I do not know if those plug fuses are rated to be used in outdoor conditions. Corrosion and other things can affect them. I cannot find a weather rating on it.

SL & TL Series, time delay, loaded link, plug fuses

I myself would replace that type.

Also heads up, that looks like a bare copper splice connector on the end of the heavy red cable. That should be insulated so it does not come in contact with ground by accident.

Hope this helps

John

Yes John, that is exactly what it is (both the fuse and the connector). I am not sure what happened that led up to someone installing it, but I know that it's been like this since my boss purchased it in 2009. I'm honestly surprised that it held up this long. I think that the only reason it became a problem is that the original battery box is no longer weatherproof.

If I can safely eliminate the fuse and install a circuit breaker INSIDE the camper, then I will do so, and I do plan to see to that splice. I can honestly say that I was shocked to find that wiggling the cable "fixed" the power problem. THank goodness for small miracles though!

Thanks for all the help!

I'll tell what that is. It is a light bulb socket that they used to use on string lighting with a house hold old fuse screwed into it. Points for imagination only. I was impressed with the burndy connector also.

Yup, that's it. A pigtail light socket. Dead on.... I can now envision the black rubber socket

Drake, that about sums it up. I've used this camper for about 4 years now, and I had absolutely no idea that it was wired like that! I recently bought the trailer from my boss and towed it home for a thorough inspection and repacking. I am the 4th owner on this unit, and I know for a fact that this 'repair' was done prior to my boss purchasing it (and she bought it in 2009 and has used it quite often since). Somebody ought to put this photo in an album of 'Redneck Type Stuff That Ain't Safe to DO!'

Usually trailer brakes (not fused +) TV charger circuit 30 amp fuse #8 wire + and battery to converter 30 amp fuse #8 wire + and a #8 ground wire - generally white.

Update on this garbage....

I've sourced a Sunline for parts. I've acquired a completely leaked on and rotted beyond repair 1992 Solaris that I'm starting to gut for spare parts. Among those parts are more modern blade type fuses that run from the battery. I'll get photos tomorrow after the rain stops. Hopefully, I can repair this homebrew muck safely now.

By the way, if anyone needs anything from an older Solaris, feel free to message me. So far, most parts are left, but I've hat to rob nearly all the exterior lights to replace my corroded ones with.
