What is the round yellow thing in the red circle? It's about the size of a penny or nickel in both diameter and thickness. I had an electrical problem with my '84 RV that burnt up two of these. They are wired in between the main wire block (where 110 comes in) and the circuit breakers. I've called a couple of RV service places and no one can clue me in. I need to know what it is and what I can replace it with. Thanks for any help you can offer.
Looks like a capacitor. Hard to tell how it is wired in the picture. Any markings on it? What brand power converter? May see if you can find a schematic.
fusible link? looks like some type of fusible link . I wouldn't worry about replacing it with something else but worry about finding the short that is causing it to blow. it looks to be doing it's job by blowing out and not burning the RV to the ground. you have a short somewhere in that circuit. yeah I had an old RV . darethea and I worked on it about everytime we came to sew trackside . the best to all. bill and darethea
It wasn't a short (I don't think) just too much of a load on the circuit running a heater and my tire warmers on the same circuit. The main breaker tripped a couple of times before these burnt up.
They look like capacitors. Probably used to reduce small incoming line voltage fluctuations. You can replace them with similar ones from radio shack. You could probably do ok without them though.
I tell you those little heater draw alot of power and then add the tire warmers to it and it will cause trouble for an older RV. Are you using 30am or 110v? I had problems with my old rv like you are so I added a seperate fuse block and converted to 30amp and no longer had any problems. I put the air and micro on one fuse block leaving everything else on it original fuses. And as long as I didnt run the microwave and tire warmers at the same time I had no problem. Now with my newish RV its 50amp so it runs everything plus a buddies tire warmers as well and never missed a beat. You may also wanna check the cooling fan for the fuse panel inside. If its turning slow the fuses may be heating up to much. Just some ideas.
After further research I've decided a replacement of the power converter is in order. This will upgrade me to 50amps and eliminate all the ancient wiring issues. Thanks for all the feedback.
You will be much happier. Problem with that is finding good power at all the tracks. Most offer 30/50 amp plugs but get there early cause the go fast. Or buy a good 6500 Genny and youll be set.
best money you could spend. If you just kept putting bandaids on it, it would wind up costing you more, and possible WAY more if that old thing caught fire.
