The high resistance caused heat alright, enough heat to melt the cable insulation causing a short?
Maybe Not

if the internals of the bat cracked creating high resistance between the plates that heat would transfer through the terminals and anything connected to it.
the short was already done inside the bat ,the heat traveled through the harness causing a melt down , the wires did not need to melt to get a so called short ,the bat did it already.
the only protection the fuse would offer in this case is to protect the wire harness but if the battery is going to blow it will take everthing around it anyway so your fucked either way.

Dan, does your POS have fuses on the battery cables?

I run dual batteries and have a fuse block on my POS.

Yep.

Well Steve. Looks like my POS is worth more than yours now. And, I drove mine today, so there!

I see your point.

It just seems odd that this type of thing would have happened this way. You'd think that others would have heard of more incidents such as this, not just Steve's and some guy with a boat. I just think the cable short is more plausible.

Dan,

I drove mine to work today as well. What POSs we have.

I'm not risking all the work and money I've put into my truck. Optimas are outa there and I just ordered a pair of Odyssey 1500s. i'm tired of having problems with these Optimas. Optima get your stuff together!

Well that Honda just runs on a few "C" batteries, no explosions.:rofl:


Shit, that's the top of the line model. You can't hide money......

Guess what--we burned up a wire on my truck when trying to install a rear light!!

Oh, but we don't really know what the hell we are doing...and I haven't read this entire thread! ;)

Glad it was just the truck Steve. Pull yer parts and slap em on another disco.

I've never had a battery explode on me (gel or led acid), but I'm sure it's been close. I welded a wrench between two brass buss bars attaching 3 Optima red top cells in my dually. Luckily I had an angle grinder within reach, and I cut the wrench off the buss bar. It was getting quite warm. :D Long before large capacitors were made for car audio, we had to use more batteries for extended bass. One of those same red tops was put in my next pickup and run daily for 4 more years. It was still in the truck when I sold it. I've also taken chunks off a terminal of a 4d battery with another wrench. Glad that didn't explode, as I was right over top of it.

How many people put fuses between their batteries and the isolator solenoid or between two hard-wired batteries? What about between the winch and battery? Funny- I never see people doing that. From what I'm seeing, the main fuse doesn't separate the battery from the hot lead to the alternator either.
Bannon- did you have a point or just being a dick? I know, stupid question, we all know the answer... dick.
Since Dan knows all- maybe he can explain how it sat dormant for 18 hours and then melted down on its own. FWIW- experts have already figured the colder than normal night and a damaged battery made for the problem. We'll take the truck apart next week and see. If *I* messed up the wiring, I'd be man enough to admit it.
Whatever- I'll buy another one if I decide that's what I want to do. It may not run, but it's still worth more than Dan's and I've got other stuff to drive.

If the battery failed internally due to high resistance no ammount of fuses anywhere would have prevented that fire.
The fuse may have protected the harness, but for what, the thing was going to burn anyway along with everything around it.

the only failsafe for this situation is a fire proof box with a lid vented to atmosphere
aviation style.

could be a good seller,instead of dual bat trays make dual bat boxs out of stainless.
and you have fireproof.

Yeah, Steve. Throw it up on the auction block and see what it brings! I hear there is a big demand for burned up 04's.......

As to answer your questions, yes, we do put fuses on the main cables of the batteries. There is also a fuse mounted (if not already in place like on most bigger trucks) between the alternator and the batteries. Most vehicles have a master cut off as well when a lot of "shit" has been installed. But, you knew this, right! I thought you said you had EMS background????? Have you not had EVOC? Or, are you just on the "search and rescue" BS team where you show up in your POV and stand around like a moron and look over topo maps as say things like "I et they're here". Yeah, I've seen your type....

On the winch, any idiot installs a master cut off. (Reminds me, I need to install one). Not only is it a security feature, but it's a cut off in case a solenoid get stuck while winching in.

Why did it take 18 hours??? Who knows. Sounds like a relay tripped and allowed power to pass to what ever POS electronic junk you had installed. Engel maybe? Cell phone charger? Rechargeable flash light? Alarm system? Who knows.

Sure, it perfectly possible the batteries fucked up. But, knowing the problems CVC has had with your POS freelander, I still say it was in the wiring.

How can a master cutoff help after the fact? Cut off your batteries every night? No thanks. Yeah, I'd like to see those fuses between everything you've got there- because they aren't there.
As for my SAR stuff- I teach FEMA 197SP and 288/301/346. I've got more months of professional training than you have teeth. An 04 with a burned up engine compartment is actually worth quite a bit I've found. Disco bodies and interior bring some big bucks.

You will not be able to give the doors or glass away. Ask Will Tillery. You have a transmission and a T-case and some drive shafts. No one even wants the POS axles. No one will want a motor thats been in a fire, no one in their right mind, anyway.

You may be sitting on 7k. My wheels and tires are worth half that. Besides that, mine runs, lol......

I'll go take a pic is a fuse I just installed after Greys Anatomy.

First, I don't know shit about wiring. I've only been doing it for what, 13-years?

None of those first pics looked much like a truck- the rest are from an ambulance... what's the relevance? Do you need me to post a pic of an ambulance and a Disco to demonstrate the differences? :rolleyes:
Your desire to argue overrides any sense of reality. Just like the thread about BWO- you shoot off your mouth about stuff you don't know. You comment on the wiring in a truck you know nothing about and reference a picture taken after the wiring was removed. Experts with real training who have seen it in person have spoken- but no, T-bone the redneck knows more from several hundred miles away. Whatever... I'm going to look at a D110 tomorrow. My truck still looks better and is worth more than yours... hahhehhehahheh.
Too bad every discussion has to get diverted because you want to argue-
