Hi, can anyone help please?
positve side battery dischaging to earth, battery flat overnight.
3 leads connected all red and thick gauge , one goes to starter, and the others I presume go to relay box, bulkhead passenger side in engine bay. had problems with starter motor but bought second hand one.
has onyone a drawing? please

thankyyou

 

You need a amp clamp really to find that mate if not could use a muti-meter between battery and the live term! Try removing live from alternator maybe windings have gone to earth

 

thank you, will try that with my multi meter in line.

 

No probs

 

You sure its not just a shit battery and not holding its charge?

 

yes am sure, have had positive lead disconnected for a day, as there is a o.3amp discarge , however i still think it could be the secondhand starter i bought.although a wiring diagram would help considerably

 

.3 of an amp is a "Parasitic" drain?

must be the used starter dragging battery down, but sometimes the spark is not at plugs?
changed coil pack, and flywheel sensor but no difference! just started the engine twice no problem then third time engine kept turning and turning

what does the ECU do? i thought it maybe the immobiliser but seems to work ok

 

No, I would say the reading you mention is nominal.

ECU = electronic control unit and basically manages the engine, amongst other things.

Are you plugs/leads decent?

If the starters draws to much current things will shut down i.e you need around 8volts to hold a relay open

 

ah, now that makes good sense. as have no problem starting rolling down the smallest of gradients . thank you. will try another starter motor tomorrow

 

well i have access to a spare car so will try those leads before i change the starter motor. thank you,

 

I remember It also happens to me when i have that car. The battery was draining overnight. I checked that I had not left any lights on or anything. But I found the problem which is my car audio player. the memory circuit was draining the battery, then I change the audio system and it never happens again.

 

you can get a current testor that sits where the fuses go cheaply from maplins this will tell you which circuit is draining the battery!
