That seems like good coverage. The starter cable connection and its mounting bolts should be in good condition. Inspect them.

After that return to the Mighty Gryphon's Reply #6 and inform us of the results of the tests in that post he suggested you try.

Starter bolts and cable must be good, as it turns over(cranks) great!

Hi.
What makes an ECU fail?

Thanks.

rbm · « **Reply #427 on:** February 02, 2019, 05:53:34 AM »

There's no one particular failure event that can take out an ECU; there are many possibilities. It's a complex electronic device and many different factors can contribute to a failure. Examples are over voltage (voltage spikes, static electricity) or over current (short circuits) conditions that destroy components on the circuit board, natural end-of-life failure of a device, over or under temperature conditions that exceed the manufacturer's recommendations, etc. Electronics will either die very early (within the first few hours) or very late; lookup "electronics reliability curve" on the net. If left alone, the ECU can live a very long failure free life spanning many decades. If disturbed or subjected to those above factors, the ECU can fail catastrophically in an instant.

Hey soggzy

Have you got a mate that can help with mechanical stuff?

And maybe photos around the tank and that?

If so you need another workshop manual, your flying brick one is good but the relay picture isn't and it has no wiring diagrams. I like the Haynes '96 edition for the diagrams are in colour. Black and white wiring diagrams give me mental indigestion.

Ok. Thank you for your concise reply.

Hi. I managed to get a Clymer Manuel literally last night. I am trying to read it now.Thank You.

And, indeed the original manual from the last owner!

Chaos · « **Reply #432 on:** February 02, 2019, 01:17:41 PM »

Usually the plug comes loose or the contacts get corroded. Easy to fix, the ECU itself if pretty robust.

daveson · « **Reply #433 on:** February 02, 2019, 02:40:59 PM »

Go back to photos and Mighty Gryphon tests or I'm worried something might happen, don't know what but it's starting to sound toxic.

No need to worry. It might be just the effects of excess earwax. Ask a doctor for a recommendation.

also i was just a couple hours from you a year and a half ago guitar teching for dave mustaine... coulda fixt it for you...

Did you discuss the conditioner he uses on his hair and whether it's as effective on sideburns?

mystic red · « **Reply #436 on:** February 02, 2019, 11:16:44 PM »

Soggz, you brought me out of semi retirement.

Why on earth are you reporting these threads? Stop it!!

Brunhilda, this is more than wack. Soggz reports another thread and you'll have to "unban" him and ban johnny again for being an a-hole bully.

DO NOT READ THIS UNTIL YOU HAVE CHECKED AND CONFIRMED THAT THE STUFF IN THE PREVIOUS POST ARE WORKING PROPERLY!!!

It is possible that the injectors are open all the time. They are powered by 9 volts from the ECU. The switching for them is unusual in that the 9 volts is applied to them all the time the ignition is turned on, and they are actuated by the other terminal being grounded by the ECU.

The way to check them is to pull off the injector connectors, turn on the ignition and check for 9 volts on one of the terminals. Turn off the ignition, and check the resistance between the other terminal in that injector connector and ground. If the resistance is low, there is a problem in the injector wiring or the injector control circuit in the ECU.

Unplug the big connector on the ECU and check the resistance again, if the resistance to ground is still low you have a wire problem. Check the injector cable for a spot with rubbed off insulation allowing the wire to short to ground. If the resistance is high, the cable is okay.

The next test is to put your meter on DC Volts and put the probes on the terminals of one of the injector connectors. While the probes are connected have a helper turn on the ignition. The voltage should be 0.0 volts or very close to it. If it is 9v, the injectors will be open all the time and the engine will be flooded. Your ECU is probably screwed up.

This all you need to do. FOCUS!!!

Hi. Just got another ecu, but am not great with a multimeter. Please walk me through it.If you can kindly tell me how to set the meter up, and which terminal on what wire,etc. Like I think I said... electiks are sourcery for me.

Soggz · « **Reply #439 on:** February 04, 2019, 07:05:49 AM »

Put the new to me ecu in. Cranked it over with a charged battery. Tried to fire, but just the same before with the old ecu. Noticed, it’s STILL over fuelling , as I found some on the floor under the join on the exhaust to the baffle. Starting to give up now...

johnny · « **Reply #440 on:** February 04, 2019, 07:44:22 AM »

greetings...

im having to look at this sideways from now on...

did you join the yahoo bmw k75 group...

how to use a multimeter...

try this video... he talks slow with euro dialect...

Soggz · « **Reply #441 on:** February 04, 2019, 08:37:09 AM »

Thanks Johnny. I didn’t join another forum, I had a good look at the multimeter show. I measured all my injectors resistance and found them all to be 0.00, so I’m guessing that’s right as they arnt stuck open.

Soggz · « **Reply #442 on:** February 04, 2019, 08:57:31 AM »

Measure currant to plugs with ignition off

Soggz · « **Reply #443 on:** February 04, 2019, 08:59:18 AM »

Measured with ignition on

Soggz · « **Reply #444 on:** February 04, 2019, 09:03:46 AM »

And with ecu unplugged... is this right? I still havnt a clue... but I’m trying to understand...

Soggz · « **Reply #445 on:** February 04, 2019, 01:27:29 PM »

Is this right?

Soggz · « **Reply #446 on:** February 04, 2019, 04:17:27 PM »

Sorry Soggz, I feel your pain, but electricity is completely above my league. However I would think, if you have a spray from the injectors each revolution, the injector loop should be fine and you should look at the issues elsewhere. If you read through the Jetronic manual carefully, you can METHODICALLY follow the paths of various sensors, that could wreak havoc to the system, air or water temp sensors fooling the computer, etc. Also I have posted a 101 starting issues page a while ago, read through that too, as it has a wealth of information, that could direct you. Even though I am not your man, but most of the members here are well versed in the problems, these bikes could face... However nobody is standing next to the bike in question troubleshooting methodically, what could be wrong and it is up to you to read very carefully through all the great literature available here to sort out this nagging issue, you are facing

Thanks. I’m certainly trying. Not quite sure what I’m doing with this multimeter though. Never really used one before. And and I’ve noticed that most of the people who has something to say on here have all gone on holiday! Do you have a link for 101 starting issues please?

haha, yeah... The multimeter is useful for you not to throw useless parts at an ailing bike. Read the starting issues page http://k-bike-knowledge.000webhostapp.com/electrical/EFI/bike-wont-start-EN.htm It has got all the values, you need and all the places, you should measure at. For example if the air temp sensor is bad, or the cables from it are bad, the computer could be thinking, it is -200C outside and will overfuel mightily...
