As per title really... Started and drove to work this morning, all OK... On way had to stop at the petrol station for some milk... Came out and it won't do anything... Wont even light up the control switch :( :(
Checked all fuses and connections and managed to get the control light to light up, but with the ignition off ::)
I've got a bad feeling that the ECU is goosed, although it's still under warranty :y :y
Quick call to Teilo tomorrow methinks ;) ;)
[edit]Should add... Can't get the laptop to connect either :( :([/edit]

Oh dear!
Not a shorted connector to the control panel perhaps?
There's a pinout of the ECU connector here. Might help to see if the 2 power supplies are making it to the ECU?

Failing that, I agree. Could be duff ECU. :-/

Thats NOT good .... :'( :'( :'( :'(
-
Not the end of the world... Runs perfectly on petrol and I've got nearly a full tank (although it was going to be a bonus for the next owner ::))
I'll speak to Teilo tomorrow and he'll probably resolve it within about 30 seconds ::) ::) At least it's under warranty :y :y
-
Best of luck with Teilo tomorrow.

As long as I can get hold of him (and I have a few methods ::)) I expect to have the problem either resolved or a replacement part on its way by the end of the day :y :y
I just hope he's not out of the country again

what system is it?

Stag 300. :-/

Spoke to him mid-morning and he said he'd briefly glanced at my email... He's rushing about getting some orders sorted before he jets off to Poland again on Friday.
He was surprised and puzzled... Agrees with my conclusion, having had another poke about, that it sounds like it's a fried ECU :( :( Said we'll speak before the end of the day but he'll probably send out a replacement to try before I have to start pulling the car apart to trace the hidden wiring :y :y
Incidentally it's something he's not encountered before but doesn't think there's been any water ingress into the ECU, even where it's mounted, because one of the demonstrations they do with the kit is have it running with the ECU submerged :o :o
Also chatted about the supplier up North claiming to be a Stag importer but wont report it in public :-X :-X
-
I agree the ECU housing is sealed well and the connector looks to be more than up to the job. At the outside it's possible that there's been a bit of salt ingress into the connector perhaps with recent weather? I'd be surprised, though.
Good that he's providing decent support. :y

Must confess... With all the troubles people have been having getting hold of him I was starting to think I'd be looking for another supplier when I do the next conversion but his support is second to none :y :y Restored my faith :y :y

Spoken to Teilo again today.
He's sent a replacement ECU out for me to swap in and see if it cures it... We're still no convinced either way but it's quicker and easier than tracing the wiring :y :y
That said, we can only see it being one of the 3 power connections to the ECU or, as Kevin has suggested, a short to the control panel. Still... Time will tell :-/ :-/

Could perhaps be a wiring fault elsewhere i.e. 5v supply to the sensors. If a short is dragging this down it might stop the CPU from starting up. Depends if the external 5v supply is separated, I guess.

He's confident that it could only be one of the 3 points mentioned above... Had a brief (1 minute) moment of LPG switch lit up and working on Monday night, but nothing at all since :( :(
Could still be a wiring fault but does look like the ECU could be the culprit! Should know by this time tomorrow :y :y
-
Any news Lazydocker?

Any news Lazydocker?
Unfortunately the ECU didn't arrive today... Must have been sent 2nd Class :( :(
Never mind... It'll only take a couple of minutes to plug it in and see if everything lights up... If not I'll be tracing all the wiring tomorrow/Saturday as I'm not used to seeing the Petrol Level drop and it's quite upsetting to have used £40 worth of Petrol in the last few days when I know that's more than I pay for nearly twice that mileage normally :'( :'( :'(
-
Right... An Update!
The ECU arrived this morning, plugged it in and there was no difference :( :( Glad I didn't do the full swap and only plugged it in :y :y
But... I found a fuse which isn't on the schematic I was looking at. Having looked deeper into the manual there's a second schematic which does show a fuse in the switched live wire, but it's not shown on the main schematic I was working from. It looked OK but tested as blown... I have temporarily replaced it with a 10A fuse (it's only 1A!) to test and all seems fine again :y :y Just got to get hold of a 1A Blade fuse now ::) ::) Unfortunately it's right down near the ECU connector but IIRCC I did position it so that I can just remove the blanking plate by the fog light and get to it without climbing underneath :y :y
-
Ahh! I assumed you'd checked both fuses. :(
It's odd that they fitted it to the ECU end of the wire, I agree.
It's also odd that it blew, because that's only a control input. I think everything is powered from the 20A permanent live.
Oh, well, all's well that ends well.
Was your replacement ECU a Stag 300 or a stag 300+ by the way? They seem to have replaced the 300 with a new one that has a 3D map rather than the 2D map of the old one. Might give a bit more flexibility in setting-up and provide a route to tuning out the flat spot?
There's also a Stag300 premium for those with OBDII cars. It monitors the fuel trims via OBDII and self-maps. 8-)
Might be something to talk to Teilo about. Mine is a lot better now that I've changed the plugs actually, not that the old plugs looked particularly knackered.

Good news. :y
How does the blown fuse look ?. Just blown or a big hole ?. I recon you can tell what sort of fault there was by the state of the fuse. If the wire's just hanging there, its probably old age, if its totally dissapeared with metal blobs, or even glass blackened, thats indicative of a serious short somewhere.

Agreed. And since that input is just a control input (high impedance) that tells the ecu to power up, if the fuse has gone pop in a big way it might point to a short in the wiring (although it's only a couple of inches from the ECU connector).
I suppose the other option is that there is bound to be some protection on that ECU input, so if there has been a big spike on the ignition switched supply (back EMF from an ignition coil as the engine was stopped, for example) it might have driven enough current into the clamping diodes on the ECU input to have taken it out.
Third option is that since it's right by the ECU (in the front wing IIRC) some salt water got inside it in the recent weather and it's corroded the fuse.
Fourth option comes under the "5h1t happens" category, I guess. ;)

Forgot all about the second fuse :-[ :-[ It was only when I was plugging the old ECU back in I spotted the holder as it's quite high up in the void there ::) ::) Having seen it I remember deliberately placing it where it was so I could get to it by removing the plate by the fog light ::) ::)
Anyway... Just got to go and get a 1A fuse, although I'm waiting for a call from the technical department to confirm it can't be higher rated.
As for the replacement... It wasn't a Brand New ECU (I reckon it was one of their demo items) but a direct swap for the one I already have :y :y
I'd noticed the new ECUs on the website so I'll ask him about that when he gives me the quote I'm waiting for... I've set him the challenge of getting the largest possible tank in the wheel well (possibly raising the boot floor by about an inch *) so I'm expecting a bit of a delay :y :y
* I reckon I could get away with buying some 1" MDF/Ply and cutting it to fit the entire boot floor (minus the wheel well) and re-fit the carpet on top of it to keep an original look :-/ :y

I'm plumping for option 3 or 4... No evidence of it "Blowing" whatsoever :y :y :y
That said, IIRCC when it packed up I switched off with heated screen and seat switched on and so the seat will still have been on when I started it up again :-/ :-/

In the 38 years I did in the aviation world, with the responsibility for looking after all the aircraft systems in flight, it was accepted that fuses age, are not made well, or suffer from vibration fatigue.
Whenever a fuse blew, standard procedure was to replace with one of the same size and repower. If the fuse blew again .. circuit problem .. investigation required before replacing fuse again. If it remained working... remind oneself to refill the "spare fuses" box and continue ... :)

Sounds like a plan. :y
I could do with getting in touch with him too. I suspect my car's due a vapour filter. This one's done <mumble>25000<mumble> miles. :o ::)

Send him an email... He's in Poland again from today for about 5 days... Or just ring the office on, errm... I'll have to find the number and PM you with it, and order one... They're about £20 delivered IIRCC :o
Mine did 25k when I changed it and TBH there was no noticeable difference in weight or flow... He did say to me before that although there is a recommended change interval most people don't bother until it starts playing up ::) ::)
-
If you could PM me his number and EMail address that would be good. :y I still need to ask him about doing an inspection too.

He was supposed to be chasing up the LPGA about full certification... I want to get mine done too before I sell it.
He can certainly do a safety certificate, which is adequate for insurance purposes :y :y

Both purely resistive loads, so I can't see a problem there. 5h1t happens it is then. ;)
I'm guessing a 1A blade fuse has a very fine filament and due to the nature of these fuses it's not well protected from contamination or vibration / flexing, etc.

About the thickness of a hair ;D ;D It was broken off on the leg :( :(
Smallest fuse I could get from my factors was a 3A... But they didn't charge me for it :y :y :y

That'll be fine. It's primarily to protect the wire, after all.
