Glowplug Wiring

**Jojo** · 24th February 2014, 07:22 AM

Hi all,
on my truck, the "English Patient", which is a 110 with the ominous Td-engine the glow plugs are serially wired. This means, if one is shot, the others won't work either. That is the situation I am having right now. As I am about to address this issue, I want to do the job properly and, if possible, convert to a parallel-wired glow plug system.
Is there anyone around who has done this already? What do I need to do and how to proceed?
Thanks for any advice!
Cheers

Didn't even realise LR had serial glow plugs as I've only seen the 200/300tdi parallel ones.

Is it as simple as fitting a set of 200/300tdi plugs, wiring them in parallel and using either the factory relay/timer, or simply a pushbutton switch and solenoid to glow manually?

The parallel wiring came first with the Tdi-engine range. Mine, a 19J, doesn't have these and is wired in series. I am not sure, the 19J-engine maybe never made it to Oz? It basically is a 12J with a turbocharger added.
From what I know I will need different glow plugs and another kind of wiring (maybe even a relay?!?) to convert to parallel wiring, but am unsure of what else I need and how to do it properly, hence my question.
Please enlighten me so I can get this project done!
Cheers

Outside my knowledge, but a quick Google comes up with a few forum references and points towards the likes of these conversion kits on ebay: Land Rover Series Diesel PRE 1983 Heater Glow Plug Parallel Conversion KIT | eBay

Good luck

Thanks mate!
That's what I'm after. The thing is, though, there I can buy the glow plugs and wires, but I could probably get these by myself if I would know the specification. Cables are easily obtained too, the thing I am wondering is if I will need a special set up as well, like a relay, which is standard on all parallel wired Land Rover engines.
I might just as well order one of these kits, making it easy, having all stuff at hand at once. As for the forum search, I did not get many references, but might have used wrong terminology.
Cheers

That kit said it comes with "Instructions", so might be worthwhile sending a message to the seller to find out what that consists of. Might find he also does any extra bits and you can get everything you need at once.

Mate,
you were right, of course! No idea, how I could overlook the obvious. Probably got confused by the fact that I could not find a relay. Anyway, no need to convert, thanks for that. Still some problem solving required as there are only 10.6V at the plug terminals. Maybe this can contribute to the starting trouble? I'll put in new plugs next, could be the easy way to solve the problem.
Cheers
