[Vwdiesel] glow plugs, killing them gently

[H . Hagar.]

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 ?
