Truck has Bad Odor, Smells like Sulphur/Rotten Eggs

just some fyi overcharging or bad batteries will put an odor like the one u describe check it out. good luck.

 

So will eating at the buffet.

 

Yep! You've got a dead cell. The bad battery will normally be swelled and definitely hot to the touch. It's a good idea to load test all of them as they are generally similar in age.

 

You don't have an engine problem, you have a battery problem. Either through corroded battery cables or defective grounding you have over-charged one or more of your batteries. You have a dry cell and that is where that horrible smell comes from. Be extremely careful if you do this job yourself because the battery or batteries affected in this state will explode with just the slightest spark or static electricity. Wear safety glasses in addition to full face shield, plus cover all exposed skin with something (an old coat for example) and wear leather gloves. Remove and locate affected batteries and set them aside by themselves away from all possible ignition sources. While batteries are out, find out what caused over-charge condition. Check your grounds from batteries to frame, batteries to starter, starter to engine block, frame to engine block, frame to cab body and frame to alternator. Also check that no main positive battery cable is corroded. If wires inside insulation are green, throw it away and have new cables made. Once all cables are confirmed good and all of your grounding locations are secure, reinstall new batteries and your good to go. On these newer trucks, all those grounding locations I mentioned including the little ground wire going to ECM from batteries is very very important for your truck to function correctly. If any are missing, install them. Grounds to your engine block and your cab body are the two most important electrical connections on your truck because for airride cabs, that grounding strap or cable from frame to cab is very important because your fuse box is where all the important circuits feeding your injectors, and ECM are located. Just use extreme care with batteries that have been cooked and remember a dead battery is more explosive than a fully charged battery of any size. I am a confirmed authority concerning battery explosions and trust me, you don't want to go there. In case your wondering why I mentioned nothing about your alternator, well that's because today's alternators rarely fail. Usually it's the cable or a connection that has failed because if either of those two items fails, the alternator has no clue how much voltage is in the batteries and will continue charging because there is no signal telling the alternator to quit charging. It's as simple as that especially on today's electronically controlled diesel engines. But run an alternator with bad cables long enough and yes, it too will fail. Check your cables and cable connections in addition to all grounding locations at minimum once a month to ensure they are performing the way they should and you'll never have an electrical problem. That's a fact Jack.

 

Thanks.
Very helpful.
For the life of me i couldn't Remeber what that smell meant BC it's been so many years since last time it occurred.
Thanks again.

 

Thanks! I had been smelling something all afternoon and that's what it was!

 

Very informative. My truck smells like this right now. Im down on my 10 n within 15 mins of me sitting here with the truck off..i start smelling rotten eggs. I thought it was the neighboring trucks but i went outside n only smell it inside. Nt outside. Im afraid to fal asleep cause idk if the fumes will harm me or kill me while i rest.idk what to do right now. So im just sitting here. But n the morning ill cll someone to come out n see whats going on. Thanks fr the information.

 

I am having the same problem..I am going to change the batteries...but my question is..can I keep driving so should this be dealt with immediately???

 

Keep driving.

Fix it when you can stop. One dead battery will kill the others rather quickly so I'd plan on replacing them all when you do.
