VINTAGEAUSTIN Posted March 9, 2008 Share Posted March 9, 2008 Just re-built my starter motor and fitted back on car today, BUT...... ......now when I press the big red button, all I get is a click from the ECU (EU2 1.6K Roadsport) and nothing from the starter I have checked all the cables and connections and cannot find anything. Does anyone have any ideas 🤔 Cheers Glynn Blatting for England in the Dordogne!! - Holidays at Chateau Marotte Link to comment Share on other sites More sharing options...
millsn Posted March 9, 2008 Share Posted March 9, 2008 Can't resist.. "Dodgy solenoid?" Have you checked the you're power is switching on to the solenoid and the condition of your earth leads to the engine / bellhousing / battery? Link to comment Share on other sites More sharing options...
shn7 Posted March 9, 2008 Share Posted March 9, 2008 Is the battery up to it? Check the voltage across the battery terminals with ign. off and then when you press the BRSB. I suspect the clicking is aactually from the MFRU rather than the ECU and is a symptom of not enough current getting through to the starter. Steve.

VINTAGEAUSTIN Posted March 10, 2008 Author Share Posted March 10, 2008 Hi Steve, Yes, it is the MFRU that clicks! However, whilst I do not have any meters, I have physically checked all cabling, connections etc and cannot find anything wrong. - The battery is fairly new and is showing fully charged on my Optimate. Any other suggestions would be gratefully appreciated Cheers Glynn Blatting for England in the Dordogne!! - Holidays at Chateau Marotte Link to comment Share on other sites More sharing options...
regroo Posted March 10, 2008 Share Posted March 10, 2008 Just re-built my starter motor and fitted back on car today If nothing else has changed then I would assume that something is not right with the starter motor? Can you wire it direct to check it spins up, at least then you would know that the battery and motor are ok? Link to comment Share on other sites More sharing options...
AndyG Posted March 10, 2008 Share Posted March 10, 2008 I had the same thing, turned out i wired the wirey bit on the outside of the starter motor the wrong way round. Its the wire that goes onto a bolt at the back. Link to comment Share on other sites More sharing options...
VINTAGEAUSTIN Posted March 13, 2008 Author Share Posted March 13, 2008 I have now fitted a new starter and yet more problems 😔 😔 When I turn on the ignition, I am not getting anything from the ECU and just a click from the MFRU. I have noticed that when the ignition is on, I am getting a faint humming from the intake area The battery is definately good and all connections are ok......... ......HELP!!

shn7 Posted March 13, 2008 Share Posted March 13, 2008 The faint humming is most likely the IACV resetting itself and is normal. Doesn't this simply say that the original problem you reported still exists and wasn't caused by a faulty start motor? It all suggests that you have either incorrectly wired something or there isn't enough amps getting to through the wiring to the starter/solenoid. Steve.

Ian B Posted March 13, 2008 Share Posted March 13, 2008 Hi Glynn, Have a look in 7FAQ/Contribute here If you've got a Battery master switch then they have been known to go high resistance, so allowing low current devices (ECU etc) to operate, but failing to allow enough current to drive the starter etc. Ian - MI 5EVN - Slightly Vider SVelte model 😬 now repainted to match the Autocom headsets 😳 Link to comment Share on other sites More sharing options...
Mick Day Posted March 13, 2008 Share Posted March 13, 2008 Glyn Do a little test: connect a short lead to the positive side of the battery & connect the other end to the solenoid part of the starter. Make sure the car's out of gear as the starter should spin & engage. If it does the problem probably lies with the starter relay inside the MFRU. If it doesn't then you have a problem with your starter. Assuming the starter spins then what to do next? The easiest way, & this is what a lot of us have done, is to fix a relay close to the battery to operate the starter solenoid. So find the original wire that goes to the starter (white & red I believe) & cut it close by the battery. Discard the long bit that goes to the starter solenoid. Use a simple 30 amp relay & use a new length of wire from the starter solenoid to terminal 87 on the new relay. 85 goes to earth; 86 is the cut end of the original wire & 30 goes to the positive side of the battery. Why a new length of wire to the starter solenoid? Well this wire runs close to the exhaust & the resistance of a wire, constantly at high temperatures will increase. I wrap mine in heat proof wrapping. Have a look at this old thread here from 2002. If you want a simple wiring diagram & a pic of my relay then send me a Blatmail.

shn7 Posted March 13, 2008 Share Posted March 13, 2008 Agree with Ian B re the FIA switch. I'd forgotten but I had one fail on me. Intermittent problem to start with which could be got around by holding the key into the on position. Steve.

VINTAGEAUSTIN Posted March 13, 2008 Author Share Posted March 13, 2008 Mick - YHM Steve, thanks for your suggestions - it seems to be a coincidence (or disturbed connection) as the only thing we have done is disconnect the battery and change the starter. - Prior to that, it always started perfectly and I never had any other issues. I ought to have said that when I connect the battery or turn on the ignition, I have not been getting any of the normal noises 'pump' etc. Ian, - Good to hear from you again - please pass on my best regards to everyone at the Ringlestone Blatting for England in the Dordogne!! - Holidays at Chateau Marotte Link to comment Share on other sites More sharing options...
Willie. Posted March 13, 2008 Share Posted March 13, 2008 Glynn, Worth checking the ECU fuse. It's one of the normal ones in the fuse box. It'll either be a 20 or 30amp. If it's a 20, change it for a 30 (Caterham now reccommend the 30amp). Willie Link to comment Share on other sites More sharing options...
tiddy1 Posted March 14, 2008 Share Posted March 14, 2008 Have you knocked the inertia switch, that will stop the pump priming. Simon Link to comment Share on other sites More sharing options...
VINTAGEAUSTIN Posted March 14, 2008 Author Share Posted March 14, 2008 A big THANKYOU to everyone It has turned out to be a combination of dodgy starter, ECU fuse and re-setting of Immobiliser! In particular, thanks to Mick for the images/diagram etc. Blatchat rules Glynn Blatting for England in the Dordogne!! - Holidays at Chateau Marotte Link to comment Share on other sites More sharing options...
