elie boone Posted January 28, 2012 Share Posted January 28, 2012 Be carefull with jump leads or a starter booster on a drained battery, the instand power surge from the good battery to the banner can knacker it instantly, the lead plates will bent and lose their function. you end up with a battery with less capacity, you can even fry the alternator on both cars in the case of jump leads.

Area Representative Golf Juliet Tango Posted January 29, 2012 Author Area Representative Share Posted January 29, 2012 Nice coldish morning but no ice on the windscreen. Friend over so I can measure the voltages. Voltage at rest 12.4V Cranking Voltage 9.8 to 9.5V No go but lots of turnover. Further information. Friday morning. Certainly colder than today. Ice on the screen. 21 in front of garage as I wanted to leave at 07:00 Lots of cranking. No firing. Got the battery out of the Crossflow (stuck in the garage behind the 21) Link the batteries together. No go. Lock everything up. Close all the doors, bonnets and such like. Call International Assistance and borrow the ex's car. Start it. 5 minutes to scrape the ice off, then go. Link to comment Share on other sites More sharing options...

Thanks Elie. It's not a drained battery. Link to comment Share on other sites More sharing options...
Area Representative Golf Juliet Tango Posted January 29, 2012 Author Area Representative Share Posted January 29, 2012 Quoting BIO: Will a bigger battery fit or two Gel batteries wired together. John, I tried two Banners in parallel and that did not help. What no-one has said (and I don't seem to be able to find out is whether gel batteries have better cold weather performance. I have read of their disadvantages and unless there is something noticeably better in their output when the mercury is low, there is nothing of advantage to me in a gel battery.

CageyH Posted January 29, 2012 Share Posted January 29, 2012 That sounds just like my car used to be... I never measured the battery voltage, but I think you just don't have enough fuel going in, so there is nothing to ignite. Change the map to the settings I sent, and try again. It's 2 degrees outside, and again it started on the button. Link to comment Share on other sites More sharing options...
Area Representative Golf Juliet Tango Posted January 29, 2012 Author Area Representative Share Posted January 29, 2012 However, with a cold week forcast, I should be able to try Cagey's map and, I hope, experience the difference. Link to comment Share on other sites More sharing options...
Jason Plato Posted January 29, 2012 Share Posted January 29, 2012 disconnect the air temp sensor - this then reverts to a 20c default setting ( which is a temp your car starts at) then try strting it . this could help identify if it's the cold starting map or sensor failure.

Fil M Posted January 29, 2012 Share Posted January 29, 2012 Its the little green coloured thing sat on the inlet housing of the throttle bodies ... when you take off the sausage shaped filter its there winking at you. Fil Link to comment Share on other sites More sharing options...
Area Representative Golf Juliet Tango Posted January 29, 2012 Author Area Representative Share Posted January 29, 2012 Thanks. I thought it might be that one. I'll just finish this batch of marmalade then give it a go. Edited by - Golf Juliet Tango on 29 Jan 2012 13:12:24 Link to comment Share on other sites More sharing options...
Area Representative Golf Juliet Tango Posted February 24, 2012 Author Area Representative Share Posted February 24, 2012 As so often, this was not a single cause. Cold weather map: Emerald is looking for 10V which won't be delivered in sub-zero temps. Coil Pack: replace. And it runs! Link to comment Share on other sites More sharing options...
Jason Plato Posted February 24, 2012 Share Posted February 24, 2012 and its now above 10C ? Link to comment Share on other sites More sharing options...
Area Representative Golf Juliet Tango Posted February 24, 2012 Author Area Representative Share Posted February 24, 2012 Oh yes. Thank goodness, it makes all the difference. I'll check what the battery makes under cranking over the weekend. (same battery) Link to comment Share on other sites More sharing options...
Area Representative Golf Juliet Tango Posted November 28, 2012 Author Area Representative Share Posted November 28, 2012 The coil pack was good for a couple of days. The weather helped. In the end, when other problems (separate thread) sent the 21 off to Ratrace we found the real culprit Which was the MRFU. Link to comment Share on other sites More sharing options...
Area Representative Golf Juliet Tango Posted January 4, 2013 Author Area Representative Share Posted January 4, 2013 But not neccesarily the only culprit as with new Odyssey (because gel has a lower self-discharge rate), new MRFU, new alternator.
