battery cables

[overthemtn]

05dsdp does anyone have problems with the black plastic casing that covers the battery cables mine is full of hole and one cable is down showing the wire. i keep cleaning the acid but it must rub on the nuts on top the batterys when compartment is shut would like to replace with new black plastic coating but you cant get in their unless your a money

Wrapping with black electrical tape is the easiest fix. You can split a rubber hose and slide it over the place that is rubbing away.

I don't know how much room you have to work with but can you disconnect one end of the cable and put a heat shrink sleeve over the bare spots? As an alternative you might be able to use liquid tape.

well its in a slide out compartment so the cables are way far in the back where the batteries are up in front so guess the hose idea is the best thats what i was thinking wrapped it with electrical tape for now
thanks for the ideas
always working on this coach never have any fun with it

well found out their are too many bends in the cable a garden hose wont work so guess its just electrical tape no wonder they put that cheap plastic black stuff over it its the only thing that will bend that much i guess

I've read here that adding a little mineral oil to the batteries cuts down on the corrosion. Do a search of the site for "Mineral Oil in batteries" for how it's done..

i have a closed system on my 05 dsdp so how can i disconnect the batteries when plugged in to my house i cant! i even talked to newmar about this problem i keep having to add distilled water and cleaning the batteries and tray

It's not normal for batteries to boil especially with current converters/chargers that float charge at a certain voltage.
Is it possible you have one or more bad batteries? Can you check specific gravity of the cells?
Split flex wire loom will protect you cables at rub points.

.If those are your original batteries, they will keep gassing more and more as they age. Actually, they are probably pretty close to their life limit. You have to disconnect from shore power, shut off and disconnect the inverter, and then you can pull everything out of the battery compartment, clean it up, and reinstall everything. Take pictures and make drawings of the wiring. New AGM batteries will solve the corrosion problem although they are quite expensive. They will keep you from having to replace the battery tray and related hardware in the future if you don't already have to.

batteries are wet ones and they are two years old at the very most.
i asked at the auto parts store the owners opinion who is about 65 about the new batteries and he said they are not worth all that money especially when i have 6 of them but thanks any way

AGM's being "worth it" is relative. You will NEVER have any acid leak issues or cleanup involved. You will never have to check the water. They will hold a charge for a very long time. They were worth it to me to never give my batteries a thought again.

Our U-2200's are over 9 years old now and still working quite well. I did put a desulphation liquid in them in 2005, then 4 oz of mineral oil in each cell. The battery compartment and cables have less corrosion than we did after 2 years in our 2000 DSDP that I didn't do anything to. I've never run a desulphation charge on them in the 9 years either.
