Nauseous or toxic odors after hooking up to electric in campground

I have a 17 year old Winnebago Adventurer, I'm the original owner, and this weekend I hooked up to electricity and experienced the above. I don't think my charger-converter is working properly, but I have solar power and I've never noticed a problem before. Would a bad converter be causing these headache and odors I'm experiencing. The odor also comes from my solenoid area above my steps and battery area. Right now I'm using battery power, so as not to experience the fumes, but I'm in a full service campground for a week and I'd like to get this fixed as I'm 2000 miles from home. Tucson, Arizona Any suggestions would be appreciated or you can write me direct if you know how to solve this problem. [email protected]

Boiling Battery off gassing. Vent the battery area and check to see if a battery is boiling or very hot.

Yes, it sounds like an overcharged or shorted battery, rotten egg smell that will choke you. Pull out the voltmeter and check the voltage at the battery with the converter charging. Then if that's OK start up the engine and check the voltage at the chassis and house batteries. I remember the night driving home from Florida in our last DP rig, 500 mile day and within 50 miles of home I smelled it, pulled off the road in the middle of nowhere GA, really, and the house batteries were really almost on fire. I unhooked the dingy and put DW and the dog in, made it 15 miles to an auto parts store and when I got out of the rig the real issue was obvious, the big chassis batteries were almost on fire. Quick check and the alternator internal voltage regulator was fried, putting out 18-20VDC. Both sets of batteries and a new really expensive alternator and some high dollar mechanic work and I got home slightly after dark thirty. It took weeks to vent out the smell, washed everything in the rig. Sometimes it is just a bad converter, sometimes a shorted battery and once in a blue moon - something a tad bit worse.

The bad thing is the idiot gauges only show low charge - never had a hint from the console anything was wrong until the smell - then the tranny went nuts, electrical systems were chiming and dinging all the way to the parts store.
