Guest Posted September 22, 2014 Share Posted September 22, 2014 Help Took the car for a run to Goodwood yesterday, the car ran fine with no problems what so ever and enjoyed a great drive. Returned home, connected the trickle charger and put the cover on (yes the car lives outside) Went to use the car today, turned on the battery master switch and nothing. I have checked out the master switch using the LC7 fitting instructions as a guide and I have 12.96 volts at the respective terminals when the switch is on the OFF and ON position, and a earth connection from the resistor That is the extent of my knowledge on these modern cars. The car is a 1996 1.4 Limited Edition (130HP) with six speed box, No 11, maybe it should be 13. The car is fitted with a Stack ST 700 Red Starter Button Flip Type Ignition Switch (Ignition Lock and switch removed in 2002 as were the above fitted) Am I missing something dead basic, I look forward to those who are the font of all knowledge to find me a solution. All was not lost how-ever as my trusted 50 year old MGB rallied to the call Cheers Gordon Link to comment Share on other sites More sharing options...

Ignition light? Lights? Fuel pump? Jonathan Link to comment Share on other sites More sharing options...
Guest Posted September 22, 2014 Share Posted September 22, 2014 Hi Johnathan It was not a case of the car not starting I had no ignition at all no ignition light, dead as a Dodo. With the battery master switch on I have lights, horn, 4 way flashers Thanks Gordon Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted September 22, 2014 Member Share Posted September 22, 2014 Check the fuse to the ECU. Is it blown and what rating is it? Jonathan Link to comment Share on other sites More sharing options...
Guest Posted September 22, 2014 Share Posted September 22, 2014 Hello Fuse rating in ECU is 20 Amp and is not blown. Cheers Gordon Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted September 22, 2014 Member Share Posted September 22, 2014 OK. Is that fuse going live when you turn the ignition on? ... I'm not familiar with master switches... can anyone spot what I'm missing... Jonathan Link to comment Share on other sites More sharing options...
Guest Posted September 22, 2014 Share Posted September 22, 2014 Just checked. With Master Switch on I have 12.93 volts on the ECU Fuse. Cheers Gordon Link to comment Share on other sites More sharing options...
Ed White Posted September 22, 2014 Share Posted September 22, 2014 It hasn't got a master switch which is off has it. I stopped to help a guy with a kit car seven a couple of weeks ago. He'd caught the dash mounted FIA cut out and hadn't noticed. Link to comment Share on other sites More sharing options...
Guest Posted September 22, 2014 Share Posted September 22, 2014 Hi Ed No my problem is no igntion circuit when I turn the master switch ON. Cheers Gordon Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted September 22, 2014 Share Posted September 22, 2014 It won't affect this ... but the 20A ECU fuse should be replaced with a 30A fuse. Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted September 22, 2014 Member Share Posted September 22, 2014 Hmmm... Bad ECU or bad connection between that fuse and the ECU or bad earth somewhere that affects ignition but not lights? Where does the ECU get its earth? Check the engine earths. Is there a convenient connector close to the ECU that you could open to check what's getting to it. We'd need a pin diagram for that to work.

Guest Posted September 22, 2014 Share Posted September 22, 2014 Thanks SM25T. I have just dug out a 30Amp so will replace tomorrow. Cheers Gordon Link to comment Share on other sites More sharing options...
Paul Deslandes Posted September 22, 2014 Share Posted September 22, 2014 you say you have 4-way flashers; by that do you mean hazards?. Do the indicators work normally when the ignition is on? Likewise, the brake lights and any other ignition switch activated ancillaries, wipers etc. If the answer is no, then it would suggest a wire off the ignition switch or the switch itself. If you have the flip toggle ignition switch, you may still have the key operated steering column switch in circuit (mine is). Are you sure it hasn't been switched off or a wire fallen off? Do you have a Vecta immobiliser fitted as they can go faulty. Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted September 22, 2014 Member Share Posted September 22, 2014 Thanks, Paul. Does the ECU fuse going live help to pin it down beyond that? Jonathan Link to comment Share on other sites More sharing options...
Guest Posted September 22, 2014 Share Posted September 22, 2014 Johnathan I will check out the earth systems tomorrow. Does anyone have a circuit diagram for the 96 k series, the build manual starts at 2001, also what type of ECU is fitted and what are these pin diagrams.

Guest Posted September 22, 2014 Share Posted September 22, 2014 Hi Pual Yes I meant Hazard Flashers.I can't check the other circuits because I cant get the ignition on. Yes it has an immobiser but this would not prevent the ignition comming on only starting. There is no old ignition switch left in circuit. I can see this is going to turn into my worst nightmare.

Member Jonathan Kay Posted September 22, 2014 Member Share Posted September 22, 2014 With that sort of wiring and dash what happens to the ignition and the warning light if the immobiliser is set or the inertia switch is tripped?

Guest Posted September 22, 2014 Share Posted September 22, 2014 Jonathan What do you mean re your 19.27 post and ignition and warning light if immobiliser set, or inertia switched tripped. I have checked the trip and it seems ok. Cheers Gordon Link to comment Share on other sites More sharing options...
Guest Posted September 22, 2014 Share Posted September 22, 2014 Can any member advise me how the red starter button and flip on/off ignition switch would have been wired into the circuits following the removal of the steering lock ignition switch. May help me in sorting out my problem. Cheers Gordon Link to comment Share on other sites More sharing options...
Paul Deslandes Posted September 22, 2014 Share Posted September 22, 2014 My question re the other circuits was to see whether some ignition switch controlled functions were still working,even if the starter wouldn't work. It seems that they don't so either the switch is faulty, a fuse has blown or a wire has fallen off. Have you checked that all the wires are attached to the ignition switch, which I assume is mounted on the dash? If you don't want to feel behind the dash or don't want to hang upside down to look, use a smart phone in 'selfie' mode or take some pictures underneath to look for unconnected wires. As the only thing you appear to have done is connect the charger, how is it connected? Crock leads on the battery? Via a cigar lighter socket? Is it possible you might have 'flashed' something when you connected the charger and blown a fuse? Link to comment Share on other sites More sharing options...
oldbutnotslow Posted September 22, 2014 Share Posted September 22, 2014 I will dig one out for you in the morning Link to comment Share on other sites More sharing options...
Guest Posted September 22, 2014 Share Posted September 22, 2014 Thanks Paul and Oldbutnotslow Charger is hard wired to battery and has never been an issue. I will check out all connections under the dash tomorrow and report back. I am sure things might be clearer if when I turned on the FIA switch the ingition light came on? It just seems bloody odd that one moment all is fine and now this still it got me home before being a problem. Cheers Gordon Cheers Gordon Link to comment Share on other sites More sharing options...
Paul Deslandes Posted September 22, 2014 Share Posted September 22, 2014 Re the switch wiring. Most likely the ignition and starter wires were removed from the old key switch and extended to the new toggle ignition and starter button. The starter button sounds as though it's fed from the cold side of the ignition switch so it only operates with the ignition 'on'. Link to comment Share on other sites More sharing options...
