G'day,

I've started this email so it will be easy to find in the future.

I've read all the emails regarding the fire on the GMC Forum.

I watched the news video:

http://www.nebraska.tv/story/29915936/rv-fire-at-mph-motorsports-race-track

And I read the Hastings Tribune article:

http://www.hastingstribune.com/news/fire-destroys-motor-home-at-mph/article_68defc1a-4ff2-11e5-a70a-f740c9d2ecd9.html

This is a summary of what I THINK I know (note that some of the information is contradictory):

1) Fire occurred on Sunday, August 30, 2015 @ around 1930 hours
2) Coach was parked at MPH Motorsports Race Track
3) Fire started while coach was parked, not running and cold.
4) Bob and Linda were at a picnic at Chautauqua Park with friends (car show?)
5) No one was injured in the blaze, which occurred just after 9 p.m., Hastings fire chief Kent Gilbert said.

Anybody think they KNOW something else?

I'd like to know if the coach was plugged into shore power.

Regards,
Rob M.

Sully,

I'm sorry but I'm confused by your statement below.

Are you saying:

A) The coach was connected to shore power and it was on when Bob left for the evening and when he returned to a burned coach the
breaker was tripped?

OR

B) The coach was connected to shore power and he tripped the power when he left for the evening?

Also is the breaker Bob referred to in the shore power box or in the GMC?

This is an interesting point, how many of us leave our GMC's unattended with power supply on!?

If I happen to connect city water to the GMC I shut it off whenever I leave, however, I've left the power on and the roof air
running often when in an RV park.

Rob M.

Rob, you don't have to be connected to shore power to have an electrical
fire start. My 12 volt line tried to smolder and catch fire when a Chinese
fuse refused to blow. Melted the plastic shield and melted the insulation.
Was a circuit installed by a Prevost shop and the fuse was the correct size.
The fuse just didn't melt like it was supposed to. Luckily I was in the GMC at
the time and pulled the fuse. Had to rewire the circuit.

Where are the house batteries located in a Royale? As an ignition source I am considering parallel, unfused 12 volt batteries and one shorted or blew up. This just a wild guess. Even if they are not parallel if the converter were running the converter would supply around 600+ watts of power into a shorted battery. It is just a wild guess. I would be interested in the condition of the battery(s) after the fire.

Jim,

Agreed!

I was trying to eliminate the 120VAC house system as a cause for the fire.

Unless of course Bob's GMC has an inverter that was supplying 120VAC from the batteries.

Right now we are just speculating or SWAGing. Bob has enough on his plate.
I will wait until he has gone over it in his head and his time is right.
In the mean time JUST BE PREPARED as best you can.

My understanding from conversing with Bob is that he was plugged into 120
at the track and the "breaker was not tripped" were his words. You will
need more clarification of which breaker from him.

Jim,

Absolutely!

My intent is to document what has / is reported whether it's right or wrong.

JUST BE PREPARED = http://www.gmceast.com/technical/Mueller_GMCer-Fire-Guide.pdf

WE put that document together and it is a work in progress, every time we loose a GMC to a fire I intend to do my level best to
assure that the cause is added to it if it's not covered already.

Didn't some famous guy once say; "an ounce of prevention is worth a pound of cure?" ;-)

Rob,
Why do you want to document only GMC's that are a total loss. It might be
more informative of coaches that have caught on fire but were saved. It is
only a matter of seconds or a few short minutes from one result to the
other;-(

I read that as it was plugged in, but fire didn't cause a short or overload to trip the breaker.
If it was an electrical fire, that wouldn't necessarily trip a breaker so long as the current didn't exceed the breakers rating.
Also, there are two, one main breaker inside the coach and one on the pedestal. One'll usually trip before the other one.

A smoldering wire can start a fire without tripping the breaker so long as the load is below the rating.
