I just put in an orange LED toggle switch for my GPS that went into one of the unused switches ( i useed the one above the lights and dash light dimmer)
Boy, Do i ever love it!
15$ for an 80 amp relay and an led toggle switch and it works Great. I recomend doing it and "nevermind"ing the stock one. I really like being able to choose how long the GPs are on for. Especially when taking it up the ski hills this up comming winter. I didnt individually fuse them though. anyone else have different GP set ups?
-
Push button switch instead.....shuts itself off--no dead battery.

And no melted glow plugs...

I have a push button (momentary) switch wired up to a ford starter relay and my glow plugs are individually wired and individually fused. (Vince style)
Works great. I can control how long to keep them on, and I can't accidentally leave them on and burn them up.

Running a toggle switch to the stock GP relay. The GP relay controls a 75-amp continuous duty rated relay, which supplies power to individually fused glow plugs.
Stock timing and temp-control, with the ability to make it re-glow (if I need it) without resorting to switching the ignition off.

Coooooooooooooolllll
more complex than my simple light up toggle :P
at least its orange :roll:

Mine in my old rabbit (1984) was off in the center position and on in the two other positions. It was on a spring and always would spring back to OFF. That ran the cheapest Ford seliniod money could buy that was fed by 4 gauge wire. That wire was fused at 80 amps and left the seliniod to the glow plugs. I eliminated the bus bar and the glow plugs were connected by 8 gauge copper wire with solidered and heat shrink connectors.....Still not as cool as Vince's set up. :lol:

So's my toggle. :D
When I get the time and a spare switch blank, I'm moving the switch up to above the headlight switch on my dash, and adding a pair of indicators. One fed from the stock indicator location, and one that gets its power from the same relay the glow plugs are on.
Apparently just because the light has gone out doesn't mean your glow plugs are off, and I wanna see if it's true. :D
-
true .. glow plugs stay on for a few seconds after the dash light is out.
-
Yes sometimes GPs stay on for as long as 30 seconds after start up. or so i have read.
I'm not sure if that's the case with our's though.
but they definately stay on for a little while. I flick mine on, 15 seconds later, turn the key and once it's runing i turn them off. How long do you guys leave them on for on average. (not winter weather)
-
I have the fast-style glowplugs. I hold the glow plugs on for 5 seconds, Crank the engine, and them hold them on for another 2 seconds. The engine starts up instantly (summer).
But I think when winter comes around I will leave them on for about 10 seconds, start the engine, and hold them on for another 2 seconds or so.
-
Yeah, I've noticed with a stock relay when the GP light goes out you wait another 5-8 seconds and you hear a click, perty sure it's the GPs going off for real.

I'm using 2 toggle switches - first one momentary contact to power the 2 relays - on 40 amp for 2 GPS. The other toggle will be illuminated and provide power to the momentary contact so I can see is there is any chance of power getting there. Down will be off for both. Here the $3.99 momentary - 85958 - Autozone.com parts

Here's the $5.99 relay - 40 amp. - PL-RY2
(http://www.autozone.com/images/products/pil/pilpl-ry2003.jpg)
and the illuminated toggle 85911 - maybe a red one rather than amber $3.99

Disconnect the sensor, get a full length glow every time, starts after 1 rev on the starter - or at least it does now I've replaced the 3 dead glow plugs
-
I used those exactly except i used an 80 amp relay and my toggle is orange.
Shortly after using this set up (quite happily thus far) i left the toggle "on" on my way home from school. They must have been on for at least 5 minutes :( :( :( :( . I think i fried all the GPS because it wont start at all anymore :'(
And they were almost NEW glow plugs ... .
*insert crying face here*
Can anyone find GPS for less than 20$ each?
This is the third time in a year i've had to get new glow plugs. I realize this time is my fault but what a financial drain. 80$!!!
What a terrible stupid stupid mistake :evil: :evil: :evil:
-
:x
I did the same thing when I had a toggle what was not illuminated. That's why for the Caravan install, I have an illuminated toggle what powers a momentary contact toggle for my G.P.
$12.99 for Bosch. P/N 80010

disconnect the sensor (blue/white wire) - if you don't want the glow or want to cut it short - turn the key.
Putting in a switch is a complete waste of time and money.
-
Its not that tricky to use the OEM glow plug realy with a manual control.It involves tracing the glow plug relay trigger wire (ground) and cutting it .Simply add a momentary switch to control the OEM realy.I used a wiring diagram to locate the wire on the back or the fuse pannel.On most AAZ golf/jettas/passats its the blue wire with yellow stripe.This cuts out the need for other relays,morwe wiring etc....Just one switch and 2 wires.
-
Meh.
the switch and relay cost me i think 8 bucks Canadian and took all of 10 minutes to shove the wires through the fire wall hole, drill a hole in one of the empty slot switches and pinch some connectors on the wires.
I don't think it's a waste of time. I think it saves time and frustration looking up wireing diagrams and not to mention how bad ass switches look on your dash!!!! 8)

My 92eco diesel is in my suzuki samurai and I want to know how can I tell how long to power the GPS. I have a 60amp pushbutton starter switch from kragen auto parts connected to the battery and to the GP buss.

7 seconds?
10-15 in the winter i guess?

you guys using a toggle switch your just asking for trouble! everytime you forget and leave the switch on you will lambaste the gloplugs and those are about 40 a crack so if you multiply that by how many times your forget full?
that expensive! and just recently i seen what a worst case relay malfunction from a shorted out gloplug! it cought the wiring on fire under the dash in a rabbit trashed the whole harness! and it all could of been avoided if the fuse was installed where it was supposed to be and not the 2 connection connected to them selves!! anyways there are simpler ways to rewire the gloplugs Vince Walden has a nice write up and 53willys did a nice setup as well! also there are 2 style of gloplugs out there fast and slow and thats the same for relays! if your abdomen about using a switch use a push button where you have to hold it in to make contact! but stay away from a switch that stays in the on position!
just my tip for the day! :wink:
thanks Duane

Good advice - my last diesel Rabbit I used a simple toggle - no lights - and a Ford starter relay. I left it or bumped it on... and lost a new set of GPs. That's why I'm fusing them under the hood pre relay, using an illuminated toggle to feed a momentary toggle to power the relays, and have 2 illumination lights for the 2 relays to show when power is actually getting to the 2 sets of GPs. A bit over done, but fail safe.

geez guys, are you deaf or what??? :roll: :lol:
pull the sensor lead - takes about ten seconds.
NO possible chance of cooked glow plugs
NO drilling holes
No running wires
No switches
Turn on ignition, wait a few seconds or let the light go out on dash if engine is cold - turn key.
KISS.

This is a solution for people with relays that don't work.
:?

You're tallking about the coolant-temperature sensor to the glow plug relay, correct?
I may try this. My Hi-Torque starter is kind of slow spinning for the AAZ engine. It's always harder to start with the engine warm, because the glow plugs don't glow. I have to pull the cold-start cable to start it when warm, pretty ironic.
Do you remember which terminal # on the relay is for the coolant-temp sensor, save me looking it up?
Also, I seem to recall there is a sensor from the starter motor to another terminal on the glow-plug relay, and that kills power to the glow plugs as soon as the starter is energised (so you don't fry the battery with two hi-amp draws simultaneously). This is correct, right? So if I disconnected the coolant temp sensor, I could start the engine hot without waiting the full 15 (or whatever) seconds, and the plugs would be "off" while the starter spins.
I guess the downside to this mod is that the plugs would switch back on as soon as I let go of the ignition key, and there would be a superflous 15 second glow while the engine ran, every time I started the engine. So you'd go through glow plugs 2x as fast as you otherwise would.

Pin T for Temperature.... usually blue/white:

I'm 90% sure the starter pin aborts the glowplug timing cycle permanently, so I think you'll be fine.
Having said that, the stock AAZ system leaves the glow plugs on for several minutes after the starter has finished, and so does the BEW system (although it cuts them out whenever the engine goes over 2500 RPM)... so there's precidence for a bit of after-glow regardless... all in the name of drivability and emissions. :wink:
-
Putting in a switch is a complete waste of time and money.
I've converted several gassers to diesel and put push buttons in the dash that control the glow plugs.
There is a benefit to starting a diesel in the cold,.. the glow plugs stay on while the starter is cranking,.. slowing down the starter.
Many times when it was on the edge of starting but cranking speed was slowing down,... releasing the button gave it the cranking speed it needed.
Wish I had some way to turn it off while cranking on the 4 door.
-
I'm a big fan of the switch so far. I don't know why people protest so much.
It's nice to clear out all the other GP wiring off the batt. terminals once you make your own relay/switch.

you my friend have obviously not read vince's write up.... using the stock wiring harness you will notice a significant voltage drop from the really to the GP's.. not to mention who the hell wants to **** around with stock wiring? If you put in your own stuff there's only one place to look if something goes tits up.. If theres anyway that i can easily rewire anything.. I do it. Stereo, Head lights, Fogs, Reverse lights, soon to be Gp's.. It just makes life easier.. and for what.. $10-15 you can't go wrong for peace of mind at that price.. lol
