Electrical drain issue with Rover CDTi ????? - Page 3

Do you have the Sat Nav drive in the rear offside? This can sometimes remain live (red neon light remains on) when the ignition is switched off. I had a solenoid installed in the feed when this was the cause of my battery being flattened.

Thanks Bigal,,, yes we do and I will be checking it later as Greeners has suggested in his earlier post! Even if it isn't the cause of the problem, it will be left unplugged, as we don't use it .....

Why unplug it then?

If you don't want to use it, that's fine, but my advice would be to leave it connected. It will keep the mechanicals in good order, will be available if your hand-held unit crashes, and when you eventually sell the car the new owner won't be on this forum asking why his sat. nav. doesn't work!

But do one thing at a time. Have you tried the glow plug module fuse yet? You seem to be keen on blaming the sat. nav. because you don't like it! It's easy to check this without unplugging anything; just watch to see if the red LED extinguishes after about a minute as previously advised.

Looking for the cause of a discharge, once you are sure you have one, is a process of elimination, a bit of patience, knowledge and having the right equipment..

My sat nav drive was draining the battery even though it turned the red light off correctly......

I had the same problem some time ago, it turned out to be the Sat Nav DVD unit the back.
It seems to happen after a common water ingress , you can probably see the water marks left on the cover. As it's been said, it's an easy test to unplug it and see how it pans out and it's free of course.
I did get deeper and cured the problem by stripping the unit down and found a ribbon cable that gets all "furred" up causing a poor connection. I posted a guide on how to do it on the forum. I'll see if I can find it and post the link. If you don't use the Sat Nav then nothing to lose either by testing it unplugged or stripping it down. Got to less trouble that going straight to glowplugs

Just a footnote to close this thread on a positive note - the problem was eventually identified as as poor connection on the alternator, which has now been fitted securely and we have not had any repeat of the problem!

Both the Battery and the Alternator are in good shape and performing as expected.

My take away from this latest round of expense and motoring aggravation - place no reliance whatsoever on diagnostic advice given by the AA patrols.

Thanks as always to club members for their advice and support.

Spain awaits - adios amigos!

Thanks David - We made it back to Spain ok - The car runs very nicely, gearbox lovely and smooth and the new lower engine mount has made such a difference! :-)

No complaints from our Daughter, who is using Chris's car currently - complete with a nice new set of Injectors!

Best wishes
