assistant: Marc, most alternators with the engine idling (600-800rpm) won't
     supply an output current much above 15 amps, that is with full field
     current applied via the regulator. The only way you will obtain more
     output current from the alternator is to increase engine speed,
     irrespective of any additional load placed on that vehicles output.
     In short, parallel connecting two batteries means that the charged
     battery supplies all but 15 Amps of the required current for the
     jumpered vehicle, which at idling is negligable in the overall current
     required by the starting vehicle when the starter is engaged.

Write your reply.

assistant: G'day Tom, Actually most automotive alternators are less efficient
     than the equivalent current rated dc generator. The main reason is the
     power diodes, friction losses due to the commutator and brush gear are
     usually less than those for equivalent current carrying diodes (for
     units rated at 35A and higher).
     However, it depends on what you mean by efficiency, (usually the ratio
     of input and output power). If you mean power to weight ratio sure the
     modern alternator beats the old dc generator every time. The
     alternators main advantage however is that it is able to spin at much
     higher speeds (up to 15,000 rpm) compared to an armature with
     commutator. The relatively lower efficiency for an alternator is
     easily justified by its many other advantages.

Write your reply.

assistant: G'day Charlie, Sorry my BBS does not carry that echo, but to make it
     on topic, I got the idea from an alternative fuel for automobiles.
     Basically the designer used "fuel cells" to split water into hydrogen
     and oxygen. The gas was stored in high pressure steel containers, then
     used as a fuel for an IC engine, no pollution, the hydrogen and oxygen
     mixture when ignited produced heat and steam (water).
     The tricky bit is not to ingnite the hydrogen/oxygen mixture stored in
     the containers. The simple way of doing this is to use a porous
     (ceramic) flame barrier between the fuel source and the exposion
     chamber, or in my case the welding torch. Ideal for precision welding
     of small components, although it depends on the available quantity of
     fuel, more current more fuel etc., Regards Peter H.

     The fluke applies around 3 volt max to a diode continuity check, less
     than 0.6 volt for normal resistance ranges, that's why diodes appear
     open circuited except when measured in "diode mode".
     Are you aware of the dangers of using silicone based lubricants

Write your reply.

assistant: G'day Mark, I 've never really thought of applying PID controller
     principles to an alternator regulator. I've always thought that PID is
     generally more applicable to industrial control processes with
     relatively long time constants involving some type of linear action
     for the "proportional component" although not always. But, I like your
     approach, however (G);
     Alternator regulator operation is basically identical to the early
     electro-mechanical vibrating contact type. It varies the average field
     current of the alternator by rapidly switching a resistor in and out
     of the field winding circuit of the alternator.
     The solid state regulator is identical in its operation, albeit there
     are no moving parts. Connecting a CRO across the alternators field
     will show a square wave voltage with a mark space ratio and frequency
     depending on load, speed and output requirements (the field current is
     usually triangular when the regulator is actually "regulating"). At
     low engine rpm, and with a load greater than the output capability of
     the alternator, the field current will be maximum (not switching). The
     output voltage of the alternator also has a small amount of
     hysteresis, without it, the regulator would be linear and dissipate
     relatively large amounts of power (12 W) at 50% output.
     I initially built such a regulator (linear) to replace the vibrating
     reed type typically used by BOSCH and Ford units back in the late
     70s. The problem with such a design is the relatively large time
     constant of the field winding. That was solved by converting the
     linear regulator to a switching type incorporating a small amount of
     positive feedback (hysteresis). This improves the stability of the
     system considerably, and is the basis of all modern alternator
     regulators, be they internal or external to the alternator. Regards,
     Peter H.

Double check the fuel for water!!!! Often water gives fuel a "rusty"
brown color.
FYI I once filled up after driving about 75 miles around town.
Immediately after leaving the filling station I started having trouble.
Two blocks away it was undrivable. Got the station to tow me back and
they drained about a gallon of dirty rusty colored water out of my tank
(yep,  luckily the tank ahd a drain plug - 77 Datsun PU). They then
drained ALL the gas out, replaced the fuel filter, and refilled my tank.
Both of us were unable to explain why NO one else complained of water
that day. Guess I got it all and they hadn't had their tanks filled up
that day.

fetched that arcing from a starter would cause battery gasses to ignite,
considering the distance from the starter underneath the engine to the

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.

be plated with something that resists corrosion. 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.
