melted wires?

[ajhaig]

Here we go again...

I noticed that the wires for our battery tender seem to be melted.

Should I disconect this?

Any ideas about what caused this?

Thanks.

Certainly something needs done. First I would spray those down with some contact cleaner and get all the corrosion and green off so I could get a better look at it.

Battery tender...

Joe,

I think that green stuff is plastic.

At the very least unplug the battery tender before you do anything AJ.

Then disconnect the battery tender and see what you are dealing with. Are the wires melted? Is it possible there was corrosion on the terminal increasing resistance thus increasing the current?

Joe is right about the corrosion.

I also would surmise if the corrosion is not the issue if you have a battery going bad that keeps the tender working at capacity 100% of the time. They may not be rated for that service cycle, and the wires may get too hot for the insulation.

Do you even use this feature? Have you ever used it?

Aren't battery tenders for when you are storing the bus?

We are at Port Saint Lucie, FL... Maybe the guy in the pink shirt will give us a hand!

Jon,

One of the battery posts is pretty corroded, could this be the problem?

What is that tender hooked to? The chassis batteries only?

What battery is the corrosion on?

AJ full timing like you do the house batts. will stay up by leaving the inverter/charger on, right? I'm trying to figure out why you even would need this. If it is for the chassis YES unhook it if it is in fact melted. Kill the chassis batteries with the master disconnect and they won't go down while camping. All we loose is the bay lights, maybe you are different.

Have you ever had to do anything with the chassis batteries. If that is where the corroded end terminal is that you pictured At minimum I'd say it is time the remove and clean those cables. While they are off you can charge the chassis batteries independently and then let them rest to see if the voltage stays up after an overnight rest to see if you might have a bad one. Jon may be on to the cause with his suggestion of 1 bad battery dragging the whole bank down thus overworking/heating the tender.

Joe,

The tender is connected to the chassis battery.

The corroded post is the one that the tender is connected to.
