Hi, hope someboody can help cos if I had hair I'd be pulling it out 
This is actually on a Citroen Relay, W eg, 1.9D lump - so basically a Ducato, however Citroen forums only tell you how to fit tin-can exhausts and boom-boxes s I thought I'd try here on he bac of running a Scudo as well
First off, it's all my own fault for trying to rework the daft wiring to the cooling fans - so lets get the kicks up the jacksee out ofthe way on that one
My problems began with the nearside cooling fan not kicking in, and the old gal overheating.
The offside fan would kick in late in the day (as she touched red on the dial) and hold the temp steady, but obviously with only one fan cooling was marginal, and any sight of a hill would see the boiling warning light pop on. So I figured I was pushing my luckand needed to sort it out. Trouble is, no wiring diagram... :/
A few days ago, with a few hours to spare, I had a look over her and checked that the NS fan actually worked by cutting through the wires and connecting directly to the battery - she worked fine, so remade the wires and then openned up the relay box on the back face of the rad.
Did some tests on the sockets, and linkng across the sockets with wire the OS fan came on fine (with or without engine running, but ignition on)
However, the NS fan wouldn't come on by bridging the socket out. Nothing.
However! when bridging from the OS socket to the NS socket - the OS fan came on! <scratches head>
What I should have done was gone and got a couple of toggle switches and wired the blinking fans up direct from the dash. But - being a smart a***, I decided that a better way would be to use the sidelight switch to trigger the OS fan relay, meaning that by just turning on the side-lights I also got the cooling kicking in earlier. So, crimping the sidelight live and pegging it into the relay connector block, and running an earth from the earth in the relay connector block (over-riding the earth coming from the temperature sender) I did just that, and lo it did work wonderfully.
I should have stopped there and wired the second fan (NS) in from the dash ad had done with it, but instead, yesterday I decided that I could smply crimp the live from the OS an to the live to the NS fan and connect the earth of the NS fan to the van and both fans should be run together via the one relay which was triggered by the sidelight switch, and problems solved.
Well, it was all good in theory, and whether in fact I'm looking at an unrelated problem that has just coincidentally occured I don't know...
I started the van (battery is a good, HD one less than 6 month old) and ran her while I futzed about checking the wiring, making good etc. I then turned her off.
Went to restart her a few minutes later and noticed that with the key turned, the glowplug light was on, but none of the others. Checked fuses in glovebox. All good. Started van. checked wipers and indicators, OK and indicator lihgt in dashboard flashes as usual. Switched off again. Went back and fnished tidying wiring, went back to start van: clickity clickety flat battery!
Got a neighbour to jump start, started fine, just gowplug light working normally, but no other warning lights. Ran for 20 minutes, switched off. Checked headlights were bright and battery charged.
Came out this morning: flat battery.
Got a jump from neighbour, glowplug light on, no other warning lights, started OK.
Took jump leads off and chucked in back.
Spoke to neighbour for a minute, and van stopped.
Turned key to ignition: nothing, not even glowplug light
Not even a click from the solenoid when trying to start, but instead whats best described as a "gowling noise" (like a solenoid chattering) which I've traced to the black box up inside the engine bay on the drivers side bulkhead (looks like an old style voltage regulator - I'm guessing it's the glowplug relay?)
And thats it... no smell of burning, no smoke, no fuses blown. Can anyone please give me a few thoughts as to what the hell it might be? please.. pretty please :/
