Pokeys fan issue resolved, keeping the bus, generator rebuild? - Tom Warner - 12-07-2006 06:56
Yes there is. The glow plugs are designed to be connected in
series...............unless of course you would like to burn them out
and have to replace them

Pokeys fan issue resolved, keeping the bus, generator rebuild? - one_dusty_hoot - 12-07-2006 07:05
Glow plugs* I don't know how you would wire them in series,
as far as I know that is not possible.
Now is you are talking about the wire being in series with
each plug the, answer is yes, but!
Here's the but.. glow plugs use a tremendous amout of current
for a short period of time, something in the order of 6-8 AMPS.
depending on the plug and to the voltage applied at the cap/tp.
If the wire coming in from the power source was attached to
plug number ONE, then a wire to plug number TWO, then THREE
and so on there is a voltage drop on each wire depending on
the current flow, an example may be 9.5V-8.2V-6.8V and so on.
As you can see the voltage=heat would drop as you continued on
down the line. (If I were to call it in series it would be this
arrangment but it is not actually in series as each plug has
voltage to ground so the plugs are wired in parallel no matter)
You can check with a voltmeter to see if the voltage drops.
A better way of wiring is from the source to each glow plug
individually with large enough wire to carry the current, or,
have a huge copper bar or line attached to each glow plug, here
again with a large enough wire to the source to handle the
current.
You can forget the ohmmeter for checking these plugs even if
you have one out and in your hands. The resistance is so low
that an ohmmeter on X1 will read zero (0) thinking of course
that you have a short from cap to shell.
I have checked glow plugs with a good battery and jumper cables.
Attach to the battery, connect the black to the shell, the red
to the cap. WATCH OUT! The tips get extremely hot in just a few
seconds. Don't keep the voltage on too long. If they glow cherry
red at the tip first then toward the shell and not pitted or
erroded badly, they are good. If they don't heat or are badly
erroded they are bad.
You can well imagine the load on the battery with 3 or 4, even
6 or 8 glow plugs, many AMPS, batteries have just ran a marathon,
now you ask then to fire the starter, hey!, give me a break!
There is something else you can do to aid starting a diesel with
glow plugs and that is to add a relay, pust button, then momentarily
use the button on/off until the motor is running well.

Pokeys fan issue resolved, keeping the bus, generator rebuild? - Doug Engel - 12-07-2006 08:03
"A better way of wiring is from the source to each glow plug
individually with large enough wire to carry the current"
This was the scheme I had in mind when I made reference to wiring them
indivudually off of a bus bar, or common connection rated for a suitable (read:
large) amp load. Granted, if one plug fails, then have the amp load rated for X
number of plugs going to X-1 number of plugs. If enough plugs go out, and you
apply current long enough, you are going to burn out plugs prematurely, but few
systems are fool proof. From what I see in how mine are currently wired, from
one to two to three and so on, the same is true of this arrangement, but the
load on the one wire gets progressively greater, hence the melted insulation on
mine. Any one, two of four plugs can fail, and the remaining plugs still get
current across the continuous wire connecting the positive lugs. I like the
heavy copper bar idea... Doug
Glow plugs* I don't know how you would wire them in series,
as far as I know that is not possible.

Pokeys fan issue resolved, keeping the bus, generator rebuild? - davidkerryedwards - 12-07-2006 08:12
The two different kinds (series/parallel or loop/pencil) that I am
familiar with are on Mercedes diesels. The Series/loop kind are
older and less efficient. The parallel/pencil type are newer and
more efficient. On the series kind, 12volt is applied to the first
plug, it flows thru the plug, heats the loop, out of that plug and
on to the next one with very heavy gauge wire with the final plug
grounded to the block. There are insulators at the top of these
plugs to stop the incoming electricity from jumping over to the
outgoing wire without passing thru the loop. These plugs lose a lot
of heat in the wires that join them together (you can see the wire
glow red). If a loop burns out, all the plugs stop working. I am
almost certain these are the style of plugs on my 82 Perkins.
The pencil/parallel plugs each receive 12 volts independent of the
other plugs and each is grounded to the block (I think). No heat is
lost in the wires that join them together. They are much more
efficient and if one burns out, the others still function since they
are independently grounded.
I converted my 77 Mercedes 300d from series to parallel and cold
weather starting improved immensely.

Pokeys fan issue resolved, keeping the bus, generator rebuild? - davidkerryedwards - 12-07-2006 08:15
Each plug would also have to be grounded seperately since the system
as it exists depends on a ground wire from the last plug to the
block (I think).

wiring them indivudually off of a bus bar, or common connection
rated for a suitable (read: large) amp load. Granted, if one plug
fails, then have the amp load rated for X number of plugs going to
X-1 number of plugs. If enough plugs go out, and you apply current
long enough, you are going to burn out plugs prematurely, but few
systems are fool proof. From what I see in how mine are currently
wired, from one to two to three and so on, the same is true of this
arrangement, but the load on the one wire gets progressively
greater, hence the melted insulation on mine. Any one, two of four
plugs can fail, and the remaining plugs still get current across the
continuous wire connecting the positive lugs. I like the heavy
copper bar idea... Doug

Pokeys fan issue resolved, keeping the bus, generator rebuild? - Jeff Miller - 12-07-2006 08:32
Tom's post reminded me of the two toggles on the control box. The
on/off one has to be on for the glow plugs to operate when the stop
button is depressed. Later Yanmar gensets have the same switch
except it is for the primer pump when stop is depressed. Check the
manual for cold-weather operation of your genset, and I believe that
20seconds is the max. glow by the manual.

Pokeys fan issue resolved, keeping the bus, generator rebuild? - Jeff Miller - 12-07-2006 08:39
Series is the older method, and as Kerry mentioned the glow plugs
are each running at ~3Vdc in the series system, would be running at
12v in parallel which would require different plugs.
Series works, but as glowplugs age the resistance changes, and the
lower the resistance the less voltage-drop across it, so the heating
becomes inconsistent across cylinders. The other problem is that as
mentioned, if one burns out you have no glow plugs.
A parallel arrangement would be a nice upgrade for frequent cold-
weather starts.

I had a '74D-4cyl and a '77D-5cyl. Never heard of the
pencil loop but that is not to say it did not exist.
On a 4 Cyl John Deere I put a large relay close to the
glow pugss, large wire to the relay and large wires to
the glow plugs, PB controlled the relay w/12v. The
voltages given were real world from an 8.0 Onan which
as soon as I get off my duff will be changed. See if
you can get ahold of some high temp wire covering or
with shield.

Pokeys fan issue resolved, keeping the bus, generator rebuild? - one_dusty_hoot - 12-07-2006 08:53
Jeff, This toggle, or, I used a push button, is what
the cold weather fellows need to get the diesel up
and running quicker, after it starts, toggle on for
a few then off for a few, this really makes a difference.

Pokeys fan issue resolved, keeping the bus, generator rebuild? - Tom Warner - 12-07-2006 10:08
You have an excellent memory Jeff.
Here is what my Kohler manual says: On a cold engine depress the
preheat switch for 15-20 (But no longer) seconds and then try to
start the engine. Only hold the start switch down for 15-20 seconds
but no longer. If it does not start let the engine come to a complete
stop and then repeat the glow plug sequence for an additional 15-20
seconds and keep that sequence up until it starts.
But just one addition relative to the glow plugs. They are wired in
series and you do not want to put 12VDC to any of them separately as
you stand a good chance of buring it out quickly. Remember in series
the resistance is the total of all 4 plugs and that limits the total
current thru any one of them. If you want to modify the glow plugs to
a parallel configuration you want a glow plug made for that purpose.
