Featured Starting problems and fixes

I checked it out yesterday, I can't remember the resistance reading but I think it was up around 500 Ohm and the sir gap between the pick up and the lug was around 0.8mm so me thinks it's OK. I'll check it again just to double check and see if I was right. But many thanks anyway.

 

Is the CDI under seat ??? is there only one CDI for both cylinders and how many coils just gives me a idea of ignition system Al

 

Hi Pete. Thanks for your ideas to date.
The CDI is under the tank, (daft place IMO) and there's two separate coils, both under the tank and in a fantastic place to get p!$$ wet through from spray off the road.
I re-checked the resistance for the pick up and its around 500 Ohm which is in line with the spec in my Haynes so that seems ok.
I've mapped out the connector and traced all the wiring to each bit of the system and checked everything back from the CDI connector for continuity and everything is ok so there don't appear to be any damaged wires etc. A bloke round the corner who's a retired electronics techie suggested that I check the CDI for open circuits. The idea being that if a component or circuit has failed you should get open circuit indication, therefore prove the CDI is fritzed as each bit of it has to work to get the mother-trucker running. Now that I've identified which socket in the CDI relates to which circuit I can get the meter out and have a prod about to try to identify the offender. This is tomorrows job as it's too cold to be mucking about tonight.

 

So no spark on both cylinders may be coils ok then being separate coils is their a test for CDI in Haynes ? its got be something common to both cylinders only things left volts, earths, shorts to ground, open circuits but would have thought these would have given you signs (engine misfire) when bike was running before sudden failure, Me thinks CDI unit spiked by charging battery surface charge needs to be drawn off before ignition switched on, you of course need to carry out your tests first good luck and keep us posted, I'm now watching the royal variety performance.

 

Hi Pete. No there isn't a test for the CDI, Haynes say there is no data available. I'm watching the RVP too, ahh Kylie and the Coorrs, happy days

 

right this is a pure guess ... if the throttle jumped to 7 thou could that be throttle body position sensor failure then cdi refuses to try again cos no sensor imput
dont want to waste your time but may be sensor not short.

 

Heres a youtube test on coils that might be useful if link works

 

Al needs one of these to test CDI http://eprints.uny.ac.id/3217/1/TEST_EQUIPMENT_PERFORMANCE_CDI_AND_COIL_MOTORCYCLE.PDF i cannot find a CDI test any other HELP with a test procedure.

 

Hi Peter the link works fine, but boy oh boy can Americans talk!!! Why use 10 words when 10,000 impresses so much more - NOT !

 

fuel on, switched it on, pushed the go button, engine spun over the rev counter went round to 7000rpm and stuck there,
need more imfo on whats bikes doing when u say rev counter went to 700 did it rev to 7000rpm?
whats it do now when you try it?

 

No problem, not a time waster at all.
When I checked the wiring back from the CDI multi-plug everything was ok continuity wise and resistance. Having spent this morning checking the pins on the CDI I think (hope) that I have identified that the CDI or part of the CDI is 'fritzed'. Most of the pins show a resistance or O/L which I'm informed is expected. If there are Ohms then the component is intact, if it's O/L it's an open circuit, if it's very little Ohms (e.g. 0 or 0.1) its a suspect bit. When I got to pin 17 (to pole 1 on the TPS) it was 0 to 0.1 Ohm, and, as the TPS connects to the Pick Up Coil it would suggest that the CDI had a mental breakdown because it couldn't see the TPS - Pick Up Coil link, therefore "does not compute" and QED "no brum brum"
The good news (well relatively good news) is that I've found two firms that do checks and repairs/replacements so I'm waiting a return email from both, links below I hope

Hi mate you need to careful as American newbie on here now

 

I stand by what I said. If I was going to make any kind of presentation - video or otherwise - I would plan it so that the info came across clearly and concisely. That way I would hope to be useful to others.

 

Yes Big Lad I know what you mean some of these videos go on and on and on, and it does seem to be lack of planning , I must add that even these vids have got me out of trouble .
Joyous greetings to all Nations and creeds, left handed people, and those who do doe dont day doe. aswell

 

All important info included in clip and if he never bothered putting it on youtube we could not use it, have you made any youtube clips???

 

Dear Peter, just because you challenge my view does not in any way change it. I prefer my information to be clear and concise. I do not suggest that you must share my view, merely respect my right to have one.

I believe my efforts to help others on this and several other forums speak for themselves.

 

We all have different opinions of the way we view different personalities as in clips on youtube, I have all seen a lot worse but I do admire the person that commits themselves to the effort in putting these clips on youtube to help others that are not sure how to do these tests so I do not have a problem in the way it may come across to me we are not all perfect it would be boring world, I personally could not do any better so would not make a comment unless justified.
