just a wild thought here.....
do you have the scan guage on all the time. have you noticed the screen going off briefly or have you experienced it suggesting a low battery when you start up? |

It is a wild thought Caterham. The Scangauge automatically dies once the ignition is off. When moving key to position 2 the Scangauge will illuminate after a while but then goes out again unless vehicle is running. I would say that with your trip meter zeroing my first port of call would be battery. Measure the voltage at the terminals before and during cranking as a start and check your terminals and underseat relays.

Thanks one and all for the replies.
Batteries are both fine, charging to main at 14.4v, all battery connections were also okay. Checked the earth again fine, time to scratch head. Don't know why but cause seemed as posts stated earth or battery! So not seeing what was wrong or readings as expected I tried to start the engine. First few times all okay then nothing, so went to find SWMBO'd to crank it over and see is I could see anything. So she leans in turns key, nothing jumps in, all dash lights etc return, so I stare into the battery box. Nothing amiss recheck battery terminals, fine, placed had on Neg cable main battery, it moves, very easily, pull rubber boot back connection to battery is fine. Hold Neg cable light pull and it moves.....check again, pull boot up over cable and yes the wing nut is loose.retighten and use locktight. Starts every time no issues now.

have you checked the battery on your key fob?
if it is on the way out it will prevent your engine from turning over even with a lit up dashboard. hope this helps |

I've had it before with the same negative terminal on the battery and said clamp.
It seems to me that either the clamp is slightly too large thus once tightened all the way up its still loose or the battery post is a shade small. As they are lead obviously multiple removals have probably constricted it and made it smaller hence the poor fit. I took the clamp off on mine and carefully gave the battery post a few hammer taps to widen it a little and flatten it a mm or two larger dia. Never had a problem since. |

managed to undo the fastening nut (had to use some effort with two 9" spanners.
the muppets who had been at this before had clearly shagged about trying to get it tight wiggling the connector on the battery terminal to the point where they had worn down the battery terminal with swarf left at the base. no matter how much the bolt was tightened the clamp was reducing in size / gripping the battery terminal. out with the dremel / mini angle grinder and I increased the gap of the split on the clamp so now when you tighten the bolt the clamp has a greater effect - one nice tight terminal / connection. put it all back together and went for a drive expecting great results; first problem the ultraguage had stopped working? and  the alternator light flashes on, then again when I depressed the clutch !!!
not only that the temp guage starts going mental, and the rev counter some more !!
and the TC lights comes on and stays on !! 
figured there must be another poor earth somewhere...... anyhow a very knowledgeable chap on here (thanks mate) mentioned it was unheard of for things connected to the OBDII to interfere with stuff....unplugged it while driving along and hey presto back to 'normal'. TC stayed on but after next drive cycle it was gone |

I know its fixed , but I personally would cut the terminal off and replaced it with another one , as sometimes even if just over tightened the clamps crack and go loose and being you have opened the split up you have put more strain on it
cut it off and get a ring terminal crimped on and fit a better terminal something like this eBay item number: eBay Item No. 291249723563 or could use it as a excuse to fit a battery isolator switch at same time for extra security layer |

thanks munch90,
will certainly think about doing just that. I will obviously be keeping an eye on it. although I've made the split bigger it's more a case I've made the split parallel. previously the split was almost closed at the top before you even tried to tighten it and hence you couldn't actually tighten it much at all. Its nice n secure now and needed only a reasonable amount of force to get it like that....very different to trying to undo the bolt. I don't have suitable sized crimps for this size of cable so could solder a lug on the end etc. - will leave for the time being. while I sort the next job (front axle). back to the obdII - I presume the scan guage must have packed in ? wouldn't be a fuse gone (I quickly checked the ones under the steering wheel)? |
