Thanks When I hold key to heat this light comes on, on bottom row in Pic, So does this mean that My glowplugs are working now ? or do I need a wire from the end plug nearest Bulkhead to battery. ?

western Posted June 25, 2020 Share Posted June 25, 2020 If the 4 glowplugs are wired together, the number 4 nearest bulkhead needs the thick Brown with Red trace connecting to it, the wire should have a ring terminal on it to fit under the nut on top of the glowplugs. Do the above should get you a operating glowplugs system, a 8 second hold of the key before cranking the engine would be god, though in warm weather it should start straight away without needing glowplugs, The timer unit is just a more elegant solution, you can add it at a later date.

Thanks So attach Thick Brown / Red from number 4 Straight to Battery. ? Is there a way to test to see if they are heating up ? It does start on the button now ,but just thinking ahead for Winter.

western Posted June 25, 2020 Share Posted June 25, 2020 the thick brown/red comes from battery via ignition switch then to glowplugs, so as the switch part looks to be working, once the other end of the brownred is connected to number 4 glowplug, that should be it, only way to test is remove the glowplugs & using a set of jumpleads & a battery make sure the glow cherry red, connect the battery negative to glow plug body [not on the threads, so the clamp doesn't damage the threads] the battery positive the the end terminal where the wires connect, hold the glow plug either with the negative jump lead or a some pliers the do get extreme hot.

kevin50 Posted July 5, 2020 Author Share Posted July 5, 2020 Finally got rear door fitted, not the best but itl do me. Anyway I did have everything working when I just mocked the wires together, but now noting. these are wires in Pic they go into the square fuse box with there own fuses. I have Green going to White and Black/ White going to Brown / White, Thats how it worked on the mock up. I only have power on the Green to White, not the other 2 for some reason. Dont know what Ive done this time. Quote Link to comment Share on other sites More sharing options...
western Posted July 5, 2020 Share Posted July 5, 2020 Those are the rear screen heater & rear wash & wiper wires, there is a wiring diagram posted earlier. Check the relevant switches & relay work Quote Link to comment Share on other sites More sharing options...

Check the relevant switches & relay work Yes this is how I have it in Pic. The rear wash still works from Switch but Wiper Motor does not. It does work straight from battery though.. With test light I get power from Plain White to Plain Green but nothing from the other 2. Edited July 5, 2020 by kevin50 Quote Link to comment Share on other sites More sharing options...
western Posted July 5, 2020 Share Posted July 5, 2020 Try new fuses in both, as for the wiper motor running from a battery but not when on the vehicle, mine did that, I had to replace it with a new motor, the shaft that moves the wiper arm/blade must of been partly siezed, & wouldn't operate when on the door & blade against the glass.

western Posted July 5, 2020 Share Posted July 5, 2020 the purple/blue trace needs a female fully insulated spade terminal, if door switches for the interior light were fitted it would go down the bulkhead in the rear corners on both sides of engine bay I'll have to check on the red/green in my diagrams tomorrow. the 3 way lug is for Split charge system, when fitted, so just tape it up & secure out of the way. yellow/black & plain black is for glowplug warning light for Left hand drive vehicles I think. again I'll check my diagrams tomorrow.

I seem to remember securing these 2 wires out of the way, not needed on your vehicle. Quote I'll have to check on the red/green in my diagrams tomorrow the green/red is left hand indicator, could be for the front wing repeater light, are yours fitted & working ?

I had it working perfect but nothing now. Traced the wire back and cant find any breaks or anything. Earth is OK. Only thing when testing with Test Light the light just say comes on, but when touching different connections the Light comes on very Bright, so does not seem to be Much Power getting to it for some reason. Any Ideas ? Quote Link to comment Share on other sites More sharing options...

After I had posted this I read trough the thread to jog my memory when we found the Black / Blue wire. Then I saw where you told me that sometimes the vehicle has to move a bit before light comes on, Then the Penny Dropped . After a good 2 hours this morning checking wires , taking connections apart, even had the dials back off to check bulbs. I went up started it up pulled out the shed, put it in Difflock and the Bloody light came on. Must try and Remember things. 😬 Thanks Mate Quote Link to comment Share on other sites More sharing options...
western Posted July 12, 2020 Share Posted July 12, 2020 Excellent, glad it works OK, good job we have all the info in this thread then. yes sometimes it will illuminate straight away, others only when the centre diff is actually locked.
