Manual Glow plug switch Location

[visotzky]

Those of you you have done this, where did you mount it?
Cheers

I haven't done this, and I HIGHLY recommend fixing your glowplug system rather than bypassing it with a manual switch. but the ones I saw were both mounted under the parking brake lever.

Thanks, How do I get at the computer, I think it is supposed to be behind the drivers side pillar. How do you remove this?
cheers

computer is in the driver's side "b" pillar, to get at it you have to remove the plastic cover that hides the seatbelt retractor, then undo the lower seatbelt bolt, pull the seatbelt out of the way, and the plastic "cup" in behind it, from there you can rach downward and feel the unit. to remove it you must undo three nuts on the inside of the air-cleaner compartment (under the driver's seat) and then you can pull it up and out through that seatbelt hole.

Thanks got it out, had a look inside looks like new. Is there anyway to test this thing Also i see mdrive sells a couple of relays, a gold and silver one. Any ideas where these are?

[Green1]

the relays that the "computer" controls are in the air cleaner compartment, bolted to the rear wall (behind the air duct)

the other component that is linked to the system and can affect this is the temperature sensor on the top of the head near the front of the engine, it has 2 wires coming off it, one of them goes to the dash temperature sensor, the other goes to the glow plug controller. (just because the dash gauge works, does not mean that the one going to the glow plugs will, it's effectively two seperate sensors in one package)

[visotzky]

Ok got to those anybody know how to test these ?, i put a test light to them and they both have power at one post but nothing on the other, key on or not.

I turned on the ignition(with out starting) no clicks, turned it of half way and back again. this time got a whole bunch of clicks real fast on and off. I tried to repeat it and got a strange buzzing sound coming from the 'puter. Computer must be dead.... right?

It's my understanding that the guys that can test the ECU's properly connect them to an analyzer that knows what the alogrithms of the ECU are supposed to be. Some of the rebuild places claim to do that. I really wonder however if they actually have the correct information for, let's say, a Delica, or if they are just doing some generic test. My guess is the latter. So then it's a question of how sophisticated their generic test is.

Just FYI, when my ECU was gone, a visual inspection of the PCB did not reveal any obvious signs of blown capacitors or electrolyte leaking out. (If it did, I would have replaced them myself for starters). You will also note that the PCB has transistors and IC's mounted on it, and while they are less likely to blow than a capacitor, they are much harder to diagnose, needing their spec's and a logic tester. However my ECU was clearly malfunctioning so I sent it off, and when I got it back it made a difference over the manual switch I had setup in the meantime.

To me this is a question similar to the EGR Valve. For example, my mechanics strongly believe that it is better to have a properly functioning EGR than one that was blanked because it was dirty, etc. The same logic probably applies to your ECU. As Glen from CCAutos put it, if you could replace the ECU which obviously contains a number of logic circuits leading to something like a 24 pin connector with a single wire and just one connection point, why wouldn't the van have just come that way in the first place?

I suspect that if you have a decent Weller Soldering Station and wanted to desolder a bunch of the capacitors and replace them yourself, you'd probably have a good chance of getting it working again for just a few bucks and a few hours of labour.

Does anyone know the capacitor values?

The capacitors are marked (I forget what the values are and my Delica is up for consignment so I can't consult), and the ones you want to replace (or the ones that generally will need replacing) are the big foil paper ones. These tend to break down over time. Don't just look at the capacitance, also match the voltage.

[Green1]

if you don't know how to read the values on the capacitors, take the old ones with you to an electronics supply store and just say "I need one of these" they'll usually be pretty good at figuring it out. If one of the capacitors is too damaged to read, post a pic showing exactly where on the circuit board it is, and I'm sure someone on here can tell you what the right value is.

One more note, I'm not sure how familiar you are with electronics, however when replacing capacitors, remember that they are polarity sensitive, so make sure you get them the right way around.

[Delicaman]

Thanks guys. I'll just pull the customer's GCU apart and read the Caps. Just thought someone remembered so I can go buy some and have some on hand to repair Faulty GCUs. I'm the repair guy who will fix the GCU's and Headlight Combo switches. I have a Hi Reliability Soldering station. Thanks any hoo..

Firstly, i completely agree tog et the glow plugs problem diagnosed and fixed.

but, while i waited for the friendly folks at cdi to unfudge me, I put my manual switch right next to my window switches.
It gets so cold here (-50) that i kept the manual switch in for those stupid cold starts. I used a push switch so that i have to keep pressure on to keep the current flowing. With a small drill hole and deburring the button looks like it belongs there.
But be aware that the glowplug controll unit steps down the voltage so dont be ham fisted with the direct current. I max out at 4 seconds on 4 seconds off.

ps i could be completley out to lunch so feel free to correct me :)

From my experience, your glow plug control system is completely dead.
That's the common symptom for the faulty control system.
