jeff, just as a point aside, if you look at two_OH_five link first pic page 2 the throttle cable cam stop has an adjustable nut and bolt which makes connection to the "throttle kicker" yours did not have this adjustment nut/bolt?

don't know if you've mentioned earlier in your posts about the strong smell of petrol when cranking your engine

Correct Steve and thanks.....I think that the 'throttle adjustor' is NOT part of my probs....
No..... ref the fuel smell.... Means i am getting plenty and it is drowning my plugs :) maybe... AAarhgh.
What a bugger etc etc shrug. I even lost the EML today...... no light.... Calling a local car mechanic/rip off guy..... I have exposed the ECU but am a bit scared to start messing with it!!!!
I dont care I dont care ..sitting by the fire... my sinisus are fooked :)... shrug :(

3 or 4 bolts to undo the ECU from the car. Pull it through into the passenger footwell and 4 bolts (1 in each corner) undo the lid. You don't even need to undo the plugs unless it's knackered and you need to send it to me.

If you call out a mechanic, they'll spend ages messing about with the alarm and poking wires and will probably change loads of things (and charge you) before deciding it's your ECU.

Thanks Chris. Going to check the AFM this morning then have a go at the ECU. Cheers.

I don't see an AFM would cause the engine management light / chattering solenoids, but could cause poor running / idling / starting.

There does seem to be a little stain just left of the capacitor, and some below it???

The pictures are a little blurry but there does appear to be a trail of dried capacitor juice leading from the capacitor (the vertical round thing).

Next step, you need to pull the 3 plugs out of the ECU, take the circuit opening relay off the side, screw the lid back on and post it to me. (The ECU, not just the lid :lol: ) I'd suggest special delivery as it's tracked & insured. If you can keep it under 2Kg it's £9 I think & not much more than normal post.

It's not a totally correct technical term no


To be complexly technical

It looks like the capacitator has let forth the magic smoke and the electric pixes have spilled a bit of capacitator juice

:) Looks like I might be sending the ECU to Chris for repair/investigation ... in the mean time, wor lass says the clickity click click on putting full ignition on is comeing from the fuel pump relay area....so.....a bit more investigation around there tomorrow...
ST205 now MOT and on the road :)

I would think if the ECU is buggered, all bets off at to what symptoms you may be getting, so the clicking is probable down to the ECU.

You will not be able to investigate any further without the ECU, unless you can get a replacement?

Jeff,
If you feel confident
Pull the lid off the relay screwed to the ecu and check the contacts
The symptoms could be due to damaged contact in that main relay

If you don't I would suggest (subject to approval) send that relay to Chris for inspection

Actually, it's not quite true. The juice is leaked, along with the smoke which is vital to operation of electrics.

For a detailed technical explanation:

Quote:
ELECTRICAL THEORY BY JOSEPH LUCAS
Positive ground depends on proper circuit functioning, which is the transmission of negative ions by retention of the visible spectral manifestation known as “smoke”.
Smoke is the thing that makes electrical circuits work. We know this to be true because every time one lets the smoke out of an electrical circuit, it stops working. This can be verified repeatedly through empirical testing.

The function of the wiring harness is to conduct the smoke from one device to another. When the wiring springs a leak and lets all the smoke out of the system, nothing works afterward.

Starter motors were considered unsuitable for British motorcycles for some time largely because they consumed large quantities of smoke, requiring very unsightly large wires.

It has been reported that Lucas electrical components are possibly more prone to electrical leakage than their Bosch, Japanese or American counterparts. Experts point out that this is because Lucas is British, and all things British leak. British engines leak oil, British shock absorbers, hydraulic forks and disk brake systems leak fluid, British tires leak air and British Intelligence leaks national defense secrets. Therefore, it follows that British electrical systems must leak smoke. Once again, the logic is clear and inescapable.

As an aside, this also explains the British tradition of drinking warm beer. All our fridges were made by Lucas.
