The poor guy had just opened AM> JE> the hood enough for the engine compartment light to come on. AM> JE> Wonder why either of those blew up? Alan, I know exactly WHY a battery "explosion" occurs. Seems rather far fetched that arcing from a starter would cause battery gasses to ignite, considering the distance from the starter underneath the engine to the battery up front and close to the hood. That is what I meant by "why". The other case, the hood being opened, turned on the hood light, which most likely was activated by a mercury switch (which is enclosed). That's the other why. AM>Not knowing exactly which part you want input on, I'll start with the AM>basics. When you put a current through a conductive liquid, like water AM>or battery electrolyte, it will separate the Hydrogen, and Oxygen through AM>electrolysis. Quite an explosive mix if in proper proportions; remember AM>the Hindenburg? AM>Most batteries now have some form of vent system that will contain the AM>small amount produced in a good battery. However, if one has a bad cell AM>the regulator overcharges the others trying to maintain the set voltage. AM>This is probably what happened on the ones you described. A car that AM>goes through a lot of batteries may have an overcharging regulator too. AM>Just in case of excess hydrogen near a battery, I like to blow a good AM>puff of air across it before making any connection. AM>Back to the electrolysis and hydrogen production... This is part of the AM>equation for a fuel cell. If you combine Hydrogen and Oxygen with the AM>aid of a catalyst, it will produce electricity. Run a current through AM>water and it will separate the H2O into two parts Hydrogen, to one part AM>Oxygen. Add a little air and you have fuel for an internal combustion AM>engine. The reverse will run an electric motor. One day, when solar AM>cells become more efficient, we may see them used to aid the Hydrogen AM>production. Combine this with regenerative braking and we may see some AM>very low emission vehicles that cost little to run (but perhaps much AM>to purchase).

Since steel and lead have virtually the same conductance IF steel could be made to be less corrosive steel would be a good metal to use, simply because the steel terminals rely upon spring tension to clamp on the battery terminal. Lead doesn't have much of that quality. * OLX 2.1 TD * Gun Control: Ability to hit what you aim at! --- RemoteAccess 2.50+ * Origin: Northern Lights! * San Antonio * 210-499-6299 V34/VFC (1:387/23) --------------- FIDO MESSAGE AREA==> TOPIC: 246 AUTOMOTIVE Ref: EGS00023 Date: 12/22/97 From: JAY EMRIE Time: 02:19pm \/To: CHRIS ZYCHSKI (Read 0 times) Subj: cool cop cars CZ>GH>Both but that requires a 1,500+ Overhaul CZ>GH>an extra quart of fluid does the same job CZ>GH>for two bucks.

RW>If you look at a schematic of an internally regulated alternator, you'll see RW>elf-excitation circuit. Roy, I think we are talking about apples and oranges here. APPLES: One statement was that a car would DIE if the battery was disconnected while the engine was running. Not true, and the self exicitation circuit you arte talking about IS there simply because the alternator was providing 12V WHEN the battery was disconnected - thus the self exicitation. ORANGES: The other scenario is when the battery is disconnected and then one tried to pushstart the car. In that case, there would be no self excitation PERIOD - internal OR external regulator.

Since the antenna mount had an o'ring f RW> gasket, I thought including a little silicone grease on the inside would ke RW>ny moisture that got past the o'ring out of the connector hole. All I can say is that the property of silicone grease that allows it to be extremely easily displaced by two electrical contacts coming together would easily allow moisture to seep through the condition you describe. A heavier grease, such as wheel bearing grease would have done better. Actually there are quite a few better materials that could have been used (a non hardening gasket cement for instance). I have to agree though, it was a good thought on the surface. Reminds me of the time we were in the Black Hills at Mt. Rushmore, Came a terrific downpour and water came pouring in one of my trailer windows. A quick look outside showed a surprisingly large gap about 2' long between the top of the window frame and side of the trailer. A quick plastering of wheel bearing grease in the gap stopped the leak until we got home and I could do a proper repair, which required remounting the window.

Most do not know it, but one of the properties of silicone is the fact that it is very difficult to remove all traces of it, therefore it still provides surface protection when the visible portion of the grease is gone.
