Diesel Odor from Front Furnace and Cold Air Return by Dinette

Yahoo Message Number: 15043
Hello

We detect a fuel odor when the front furnace runs, or when the kitchen ceiling fan runs. The odor is traced to the cold air return to the front furnace and the warm air itself.
The furnace sits in a sealed bay adjacent to the fuel filler on curb side and adjacent to the fuel tank.

We also have experienced difficult enging starting because of fuel starvation.

The fuel filler hose in the wheel well is old and shows minor signs of leakage at some time.

Has anyone experienced this problem?

Could a minor leak at the fuel filler pipe hose cause the above problems?

Thanks

Sounds like you need to stick you head in the sealed front furnace bay. It doesn't take much diesel fuel to stink up a motorcoach. It could be you have a very small leak in your filler tube. And some of this could be causing the odor. I'd also check the bottom of the fuel tank for any fuel. I've got the same year and model as you and have not experienced the problem.

I did that. It appears the former owner, four or more years ago, had the same problem. I found a spent deodorizer hanging in the furnace space. Guess I'll have to change it at least every three years.

I also will change those filler tube hoses and clamps.

Thanks

Just a thought? When you fueled up, could a small amount of fuel dripped out around the small door for the fuel cap. Was wondering if this could have ran down the inside of the body fiberglass near the furnace.

I've got one for you. My batteries weren't charging. Hummm Crawled in the basement, took off the cover and started checking out the converter, along with everything else down there.
Gee, converter wasn't working. Checked the breaker in the bedroom. It checked out ok. So, now I have a problem between the circuit breaker and the converter. No voltage at the outlet that it is plugged into. I'm thinking it could be the outlet or the cable. Had any problems like this? By the way I unplugged the converter and ran a short extention cord to one of the outlets in the cargo bay. System fired right up. So, I know the converter and circuit are working.
The outlet is really a Beast to get to.

Hi Steve;

We are having a similar problem on our Magna. Here is what we are experiencing:

The failure mode is always the same - first, the TOTAL COACH SYSTEM (TCS) green menu LED starts blinking, along with the red 'Overall Status' LED. Both the green LED's for the 120V and the INV are on steady. The main (time) display shows an icon (word COMM with a wrench over it). Checking the INV status, it will display INVERTER = STANDBY, CHARGER = ON, MAX AC DRAW = 24A and the normal values for the AC and DC. I have learned that if I catch the TCS during this mode and turn the HOUSE BATTERY DISCONNECT off and then on after a short wait, the TCS will reboot and return to normal operation.

However, if I miss this 'window of opportunity', after a short period, the TCS then displays what I call a checking mode. The green Overall Status LED will go out, the yellow overall status LED will light blinking, then in this sequence, the green 102V LED will blink and go out, the green INV LED will blink and go out and the green START LED will blink and go out. If comm is re-established, the Overall Status yellow LED will go out, the Overall Status green LED will light, as will the 102V and INV green LED's and then the Overall Status red LED will go out. Then, looking at the INV display, the normal, typical data is displayed; but usually the CHARGER is putting out 14.4-6 volts.

If Comm is not re-established in this checking mode, then the TCS displays off for the INVERTER and CHARGER, and all the values are at ZERO. The 120V green LED is steady on, along with the yellow and red Overall Status LED's being steady on. Lastly, the main (time) display shows the word BATT with an icon of a battery over it and an exclamation mark (!). The only solution then is to do the hard reset of the inverter. The procedure for resetting given to me by CC is to unplug the middle Comm connection, then move the by-pass switch to the up position (off or by-pass), count to 20 to allow a cold boot of the inverter, move the switch down to the on position, then re-connect the middle Comm connection. When I do this, the inverter or transfer switch makes a contacting noise upon movement of the switch to the bypass position. When I move the switch to the on position, the inverter hums and the cooling fan comes on. Each time I do this the Total Coach System returns to the nominal settings, with both the 120 vAC and the inverter green LED's illuminated, along with the "overall status" green LED. When I check the inverter information, the vDC output from the battery charger is typically in the 14.5 - 14.6 vDC range.

CC is working w/SilverLeaf on this right now, initial thought was a poor comm cable connection, now leaning toward the SilverLeaf interface module. As we find the solution, I will post it here.

I live in era when switches were switches. I've got a 1995 Magna. I'm looking at replacing the circuit breaker first. My trusty multimeter indicates a problem with it.
It's down to: power at the breaker box. Several of the circuits a working. The wiring or the outlet that the converter plugs into.
I can hardly wait until we move up to a newer coach: MORE WIRING AND COMPUTER MONITORING SYSTEM. GOD IT SOUNDS LIKE FUN!!!!!

Which batteries aren't charging? I would assume it is your house batteries? Does your generator battery get charged? If so, then the problem is not the inverter/charger but some switch or solenoid maybe in the front electric bay that directs flow to house battery.

I just replaced a failed isolator in that bay which isolated the generator and house batteries being charged by the invertor.
However, that failure caused my house battery shut off switch to appear to not work. That was because the generator battery was running the house circuits when the house shut off switch was off.
Failed isolator.

It sounds like you have shore power to house circuits, so transfer switch is working. There are some switches on the inverter that could act like breakers as I recall. Have you cycled the inverter on and off to try to reset?

Whoops, I should read more carefully before posting. Sounds like you found the culprit through your testing. So disregard previous post. Have not had that problem, yet, but my coach number is higher than yours so maybe sometime soon.

WELL Dean: Now for the rest of the story. I have half of my circuit beakers not working.
Converter, two roof a/c units and block heater. I have one dead line in.
I got into the box in the electrical bay. I have one dead line. So, in reality, in might be the 120v connector on the side of the coach, corroded connector, or a bad cable coming from the house to the coach. Tomorrow, the rest of the story. As soon as I find out what the heck gives.

Steve, I just went through this myself on my '00 Intrigue, I lost leg 2 or the entire left side and front of the coach (front TV, satellite, stereo's, 10 outlets) leg 1 on mine is the right side (bedroom, both roof air's, fridge, washer/dryer, microwave, rear TV)... mine was an invertor failure on leg 2, so I just replaced both circuit boards from Xantrex. Then I found the original transfer switch was weak on the inbound to leg 2, so I got a new transfer switch, and I also bought the EMS w/remote from Progressive, and replaced my factory surge guard with the EMS. I will say this, my coach is now noticeably very responsive to all electrical functions, and I'm very happy with what I replaced. The EMS box could be a coach saver... CC installed the surge guard AFTER the transfer switch on mine, and I think I got zapped at a Kissimmee park, that weakened the transfer switch further and took out leg 2 of the invertor somehow. I was seeing 13 volt fluctuations at this particular park (time of day dependent), monitored at the transfer switch inbound lug.

The replacement SilverLeaf Total Control System Interface module was installed Saturday AM. Since installation, we have not had a COMM failure, not an inadvertant Inverter/Charger shutdown. The new interface has a new version number, indicating updated software.
