RE: [doc] Starting problems

Hi Jordan

I copied the posting I did below with the details, let me know the voltages
you get.

Just to keep you upto date with the historic problems that my De has
had. The De has always turned over very slowly when cranking the
engine over. It results with sometimes it will start somtimes it does
not. This was put down to the battery being falt recharge the battery
and it starts o/k. I could not believe this could be normal as it
should spin the engine over quite fast not s l o w l y.

I checked the volt drop between the positive battery terminal and the
starter (no volt drop) and the negative battery terminal and the
starter motor casing (2.5 volts drop!)(THIS IS WITH THE BEING CRANKED
OVER). The problem seemed to be an unaccesible earth strap, however I
think the the problem is the shear number of different earth
locations before it actually gets to the the starter motor casing.

If I measured the non cranking voltage, there is virtually no voltage
drop at all. The resistance I calculated was about 0.05 ohm which
cannot really be measured on a conventional meter.

I bought 2 metres of very heavy grade sheathed earthing cabling,
connected and soldered lugs on to each end. One lug was connected
directly to the battery negative post the other was threadled through
the original hole in the battery compartment over the trailing arm
cable tied to the water hose mount then bolted directly on to the
centre bolt which holds the starter motor on. This cable is in
addition to the original equipment cable not replacing it.

The car had been standing for a couple of weeks and the outside
tempreture was about 2 degrees, so I did not expect it to start.
Turned the key, the starter turned about 5 times faster than it had
ever done before and the De started a treat!! No problem.

If any one has similar problems let me know, I will fill you in on
any other details.

Thanks Kevin, I'll have to get a voltmetre and try it out. I'm sure it
will be the battery has only been in since christmas! Is an earth strap
hard to install?

Hi Jordan

Can you measure the voltage on the battery directly, if it is around 12
volts then put an earth strap in.

Regards


Kevin

Hi all,

I went to start my D today and yet again it wouldn't start. The
engine turned over a couple of times then stopped. The battery gauge
reads less than 8 but everything electrical works, even the cooling
fans???? I'm sure it's not the battery because it's just had a new
one and the problem only seems to have started since it's got cold.
I've read something about the cold start valve but didn't really
understand it. Is there any way to stop this happening for good?

Thanks,

J
