hot starting problem

Post by Welshcarawagon » Sun Jan 13, 2019 5:15 pm

Hi all, happy new year to everyone

Hoping for some help from you technical lot!
Carol the welshcarawagon is playing up

She’s a series3 fitted with a discovery 200tdi
She starts from cold with no problems but ad she warms up she gets a bit more reluctant until after an hour or so when she’s really warm she refuses point blank to start and I mean when u hit starter button absolutely nothing! No clicks etc
Leave her for a couple of hours and she’s back to starting!
List of what’s been done
New optima battery
New starter( she’s on 2nd new one just in case)
New alternator
Earths checked with an extra new one to starter
She has key ignition with a separate starter switch- which I’ve just replaced
My garage who restored her spent a day trying to find fault / checking connections etc and thought they had found earth problem hence extra earth cable but it’s still there!
Even tried bing jump leads from battery to starter still nothing
It seems to me there’s a connection or something getting warm and losing contact until it completely breaks when fully hot then once she’s cooled she’s ok
Any help would be gratefully received as I can’t go anywhere and switch off unless I’ve got 2 hours to spare!!
Many thanks
Phil

Hi Phil,

When you say jump leads to the starter, was that +ve and -ve, or just +ve?

If you connect directly from the battery with both jump leads, -ve to the casing and touch the +ve to the large terminal nearest the motor on the solenoid, does it spin?

If it does, if you connect the +ve to the other large terminal (where the battery lead connects), and a wire from there to the spade terminal on the solenoid, what happens?

I realise this only happens when it's hot, but you say you've got a couple of hours before it starts again, so hopefully that should be plenty of time to do those tests to prove it on to the starter or not.

Obviously, if you or your garage has already done those tests, it just has to be the starter, despite it being new :stars:

Hope that helps,
Robin.

Hi Phil,
If you do manage to fix it, please let us know how you did it.

Mine does this sometimes, but not often enough or for long enough to diagnose. Usually a few taps of the starter button gets it going again.

The starter was replaced with a brand new Bearmach one fairly recently, before that it exhibited the same symptoms as yours does now - 2 hour cool down time required after a long journey.

Now it's just a few minutes it's a not a huge problem, but more of an annoyance.

Thanks,
Patrick

Could it not be an earthing issue? I had similar issues when I transplanted a 300Tdi into Dora. One earth strap wasn't connecting properly after running the car for a while. The metal wires expand and create more resistance because of hair line cracks in the individual wires? When I connected one jump lead between the engine block and the -- of the battery, it started straight away. I too had been faffing around with changing starter motors etc. to no avail.

Just a thought...

Hi all
Finally had time to have a go at starting problem again
It’s been back into my garage for them to have a look - thought it was sorted they found batter positive cable was only just touching going into battery clamp - I picked it up drove 20 miles home and for the first time ever it did eventually start - I switched her off and alas no more starting!
Since then even when cold she won’t start - turns over very slowly - used another battery just in case then hd jump leads to discovery td5
But no go!
So Friday got another starter under warranty and it’s worse! Hardly turns and sounds strange!
It’s a recon Bosch so I’m now going to try a new bearmach and see how I go!!
Bloody thing will be on eBay soon at this rate!
Cheers
Phil

Just fitted a genuine Bosch recon starter ( less than 10 mins since I’ve done it so often!!!)
And she fired up instantly!! What a difference to the last 3 new starters
Turns out last 3 which I thought were Bosch were in fact just Bosch casings which had recon inerds
by remy - so far extra £60 we’ll spent!
I don’t know if it’s solved hot starting issue as I need to go for a 20 mile run but fingers crossed
Also I’ve heat wrapped the part of the exhaust that is pretty close to the starter Incase heat was causing an issue
Will update ASAP
