Yea easy to check that but worth it. I know you said about vacuum test, I just don't have a guage yet. Also my batteries don't seem to turn it over that fast or for that long. I have a 95ah Halford battery that came with it and a less than a year old napa from my x5 and neither last that long before needing charge. I'm sure it's unrelated but weird as it spun my 3.0D six cylinder engine up for ages.
Very true, unrelated to issues I think but was an observation nonetheless.
Yes ok I'll do some poking tomorrow. Er...ECM...engine control module, VCV or PCV ?? Control valves.....volume and positive crank ventilation? Is that the one in the top of the y piece? I took that out and it was all cruded up with black stodge. Sorry I'm not used to the terms... I do air cooled VW's with points and carburettors
So interestingly battery just been fully charged ignition off 12.5v, ignition on 12.1v, cranking 9.9v !! I am presuming that's not really enough to make it go broom. It is sort of trying with every rotation.. I must admit it sounds like it needs a boost pack on it but sadly mine has died. Is it OK to jump these or a big no no? Cheers
9.9V is either a battery on the way out or the starter drawing excessive current, neither will help as the voltage at the control modules will be below what is required.
Wow, ok..so just to be sure do you mean turn on heated screen and blower on dead disco while attached to donor vehicle?
It is easy to go off at all sorts of angles you must remember that it was going along the road and died this is not going to be a tired battery, (this maybe another problem) when I was working on my van I disconnected a injector (with everything off) and used a volt meter on 250v ac to see if I got any sort of input into the injectors, I have also used a meter on Hz, all you are looking for is signs that something is being sent to the injectors if no volts then that point to the problem being electrical of some sort, normally if this is a problem it will fire on easy start
Ha, yes can't help but get back to the topic of easy start
. Still cannot understand why it doesn't fire with it, but will remove an injector if I get chance tomorrow and check functionality. CheersYeah i sort of agree but it's less than a year old and spins my x5 over no problem at all. Strange.
Mm, ok. Yeah literally just come off charge. I have two decent (well they test as decent) batteries and they are both the same with regards to voltage drop.
I only have a load tester, one of those cheap things with a guage and a switch that heats an element to put them under load.
That should be fine, what voltage does it give?
Well actually the one that came with the truck is showing 12.2v and 11v under load, which should be fine. The one from my X5 now seems knackered so maybe a battery is in order before moving much further on with this. I thought I had that covered but apparently not. It's not the root of the problem but won't help.
