Another Bird fire

[mbulriss]

Hmmm, my inspection of my wiring over the last few weeks discovered a similar
thing: someone, presumably Bird, routed a ground cable directly together with
the positive cables and it was tie wrapped all along its length and right down
on top of a stud connecting two positive cable lugs together!!! That was along
the heat shield between the engine and batteries. Luckily the stud had a rubber
boot that was on cockeyed, but had protected the ground cable. I am going back
and look one more time for any more of those.

I think it should be pretty obvious that all high-amperage, unfused battery cables ought to be checked carefully.

That would include the house batteries -- in a '95 those are contained in the rear-most curb-side compartment and on a tray by the engine. In addition, there are 3 engine batteries above the 2 house batteries near the engine.

The house batteries are wired to a general distribution panel on the curb side of the firewall. The engine batteries are wired to the engine -- but also have a connection to the house batteries (as you can tie them together with a switch on the dash).

The Bakersfield fire _might_ have been caused by a short from the house batteries and/or the firewall distribution panel. (We await further word from the fire inspector and/or insurance adjuster.)

Randy's fire was caused by a dead short in the front most, street side compartment, where the battery cable (running 40-some feet from the curb-side rear to the street side front-most compartment) that serves the generator starter motor. Apparently, from the report of the fire inspector and insurance adjuster, it appears that the insulation had been compromised where the heavy cable passed over a frame rail.

We all may have been a little complacent over the 12v systems, since 12 v current rarely causes much of a fire or electrocution issue. It's easy to forget just how much potential amperage that the batteries can release in a dead short.

The suggestion to install a high-amperage (slow acting) fuse on the batteries makes a lot of sense. A slow acting fuse is required since things like the engine and generator starter motor can draw a brief, very high amperage burst -- and you don't want to blow the fuse. But a short would cause a longer drain, and would blow the fuse.

Of course, a careful inspection of all the high-amperage wires is called for. Unfortunately, wires may pass through areas where visible inspection is difficult or impossible. (Mirrors mounted to extension handles and flashlights would be quite useful.) Even so, it's likely that there are places where thorough inspection will prove impossible. (Which simply increases the importance of fusing the batteries.)

Another 'wise' modification would be to install a high-amperage switch to completely isolate the batteries from the coach. Marine supplies sell such switches for boats and they can be adapted to motorhome use quite easily. The added advantage of such a switch would be to ensure that all phantom loads (which BBs have in abundance) would be cut off, allowing longer storage periods without a charger on the batteries.

In the Bakersfield situation, it's hard to discern how the fire might have been avoided. The owner reported that he'd inspected the wires (as best as he could) after hearing about Randy's fire. It is unlikely that any of us would have shut off all the batteries while in a nearby restaurant for dinner -- but fuses _might_ have saved the coach, had they been installed. (Then, again, pending a final determination of the cause of the fire, it might not have been effective.)

probably best to leave things as they were designed by BB and maintain the
design. On my bus the design has a proven record of 48,000 miles and 14 years.
many things done in the spirit of safety are not obvious.your fuse mod may be
plagued with fault

on a car, crap like lead battery cable ends on the battery post are by design
less secure then the other battery cable end connected to the starter so an
accident would cause the cable to break away from the battery and not the
starter. modifications like slow burn fuses should consider all the variables.
I wonder how much heat the slow acting fuse produce.I wonder how many more
connections and failure points are created with all the safety mods members will
add during this rush for safety. every high amp connection has two soldered ends
that need to be secured.

One big question for me was why did the BB engineers use glass fuses and
resettable beakers in different areas. I like the resettable breakers
convenience but fear the lesson learned when a function trips a fuse and was
reset automaticaly with out alerting my attention is lost. I replaced my brake
lght auto reset with glass for this reason.

We are up to 3 coach fires, Randy, Rob and R.E. (Ron) Marabito

All the coaches are 90 to 95 vintage. If they were Airplanes they would
be grounded, until the problem was found.

Folks this has gotten to the point where I for one will have my coach
wiring inspected from Bumper to Bumper by the Pro's. I've been all thru
everything I can get to. So did Rob from what I've heard, and there was
still a Gremlin in his coach.

I've always had Gremlins in my Bird, just part of the program.

I no long consider this just coincidence, So until I can have my coach
inspected by not one but two or three different professionals, (Prevost,
Whites Creek TN, Hemphill Bros, Nashville TN, Maryville Marine/Xantrex,
Whitehouse TN )

Any T-Fuses that I haven't already changed will be replaced with a
proper fuse holders, not a the pipe stand off with the fuse wrapped in
electricans tape, that BB used to hold the fuse. Any qustionable wires
will be replaced. Possibly Fuse the Batteries, anything else that can
make my coach safer. It's become obvious that there is a problem with
the design.

Until then.

Indulgance is grounded.

Exellent comments Pete, but readers should be cautioned that fuses in high
amperage cables may not provide complete protection. Consider a 200 amp fuse
placed to protect a main DC supply cable. An insulation breach can start slowly
and generate a great deal of heat without popping the fuse. In areas where
engine heat, oil, and abrasion are present, the resistance of insulation can
break down and start generating heat long before there is a full metal-to-metal
short. By the time the breach gets bad enough to pop the 200 amp fuse enough
heat may have been generated to start a fire.

Fuses are very important, but vigilant inspection is a must for safety.

The house battery bank, that is on two slideout trays. These cables go to a
terminal block on the frame right behind them. It is possible that the cables
can be compromised when the batteries are moved back into position. The cables
have extra length to allow you to slide the trays into an open position.

I haven't done mine yet, but I would suggest splitting a water hose and slipping
it around the battery cables to prevent them from chafing together or rubbing on
the frame.

The plastic insulation or outer covering of the cables is what burns. This
in-turn sets oily engine compartment insulation and other materials on fire,
then moving into the coach interior. Lots of flamables in the closet area right
above the house batteries.

I had the advantage of being present when mine caught fire. The other two
members were not present when their fires started.

Sorry Greg, but the fact is: it was the battery cables and not other issues in
my case. Absolutely not damage to anything else except the cables and shunts.
Having looked very close at my damage, it was pretty obvious what hat taken
place.

Curious about you thinking I didn't learn anything from the engine re-build.
Just exactly what are you incinuating?

rebuild . now with the rewire of your rig leaving many more mods and changes,
chances are there is a next problem waiting to happen. I suspect Rob will do
like Randy and not hide opinion and review in fear of conflicting with the best
return on an insurance claim.

thinking of closing this area off with a thin sheet of metal but wonder if it

Good to hear. Apparently this inspection saved another coach from going up in
flames.
