[Vwdiesel] Slowing death of Glowplugs

[Mark Shepherd]

I think this confirms what I said about the vulnerability of
the plugs. It also makes me want to set up the passive LED
system and using the blocking diodes in each GP supply would
reduce the applied voltage and  power output of each plug.
Being able to turn off the glow plugs as soon as engine
starts also helps and this is now incorporated into my
Quantum.

I have had at least one experience where boosting a tired
diesel in winter
from a healthy truck with a good alternator resulted in most
of them going open.
I suspect the boost (at 13.6v) from the healthy truck, with
big cables, was
more than they could take for any length of time.

Sandy are we dealing with the OLD style plugs ?   if so
from 11 Volts to 13.6  will
kill em fast.
Remember the square LAW ?   double the voltage  gives 4
times the heat.

I have no tables for heaters  but Lightbulbs   according to
Westinghouse goes
as follows.   Increase voltage from 100   to  108   reduces
life to  50 %.
Reduce voltage to 92 Volts     life is increased to 310 %.
Glowplugs are probably similar to Lights.

What kills em ?  ---HEAT.          pure and simple.

Does a glowplug do any good at reduced voltage
  ---absolutely. Make a step
down resistor system and have lots of AFTERGLOW.

Will explain how I did it some other time..    By the Way
the red wire with 4 white
stripes ?   ----VW   1980 ?  it is bigger than # 12 but
smaller than # 10   ---so we
are looking at slightly more than 1 OHM per 1000 feet.

VW wire gauges are mm square. ---- way better system than
that garbage USA wire gauge shit.
Mark Shepherd what is the standard in the UK ?.
In Denmark it is square mm  simple to use.  2.5 ?    house
wiring. For DC just double for
double amps.   Try that on a USA system ?-.
USA is a retarded ---- outmoded  STUPID  system. IMHO.
Brown and Sharpe wire gauge ?

Bigger number smaller wire ?   go figure.    ---I tried but
it -- it is still STUPID.

As you go bigger ?    0    and 00   and 000  and so on ?
Anyone know of somethig
dummer ?
