Hello and Welcome..

My name is XXXXX XXXXX Im happy to help you. I had to switch us out of CHAT Im afraid as its not working as it should at the moment.. so we are now in QA which works fine..

I need to just ask - you say the alternator "seems" to be working ok - have you had that checked for accuracy at all - ? If not - do you have a meter that you can use to test it / test that circuit ?

Too - how long has this been happening ? Can you tie the start of it in to anything at all - perhaps a time when any work was done on the car etc?

When the engine is running - or switched off - do you have any lights on, on the dash at all?

Also - what exactly has been done /checked already / so far ? ( apart from the battery )

Rgds, MIKE..........................

okay... Checked the alternator with a voltmeter and all seemed fine... charging at 14.2 volts +


Happened first the other day when my partner was driving with the baby on board...


Only other issue at the mo is a leaking rear brake cylinder which I am in the process of fixing but am waiting for brake pipe flange tool...


Drains the battery when the engine is switched off not immediatly but with in 20 mins or so... everything working fine while engine running...


cheers

Hello and welcome to just answer.
do you posses an AMP meter?

Customer: replied 2 years ago.

Hello Rob, Thank you for the response... I have a multi-meter that you can test amperage with, I am not completely sure how to but am a quick learner... to do that does what ever you are testing have to be under load?

Expert:  Rob replied 2 years ago.
Hi.
with the meter we will test all circuits no load .
with the ignition off disconnect the positive terminal on the battery .
place the meter probes one on the battery terminal and the other on the positive lead .
turn meter on to AMPS then start to remove fuses one at a time replacing before removing the next .
looking at the meter we should not see any more than 0.4 amps drain this is normal so if it is higher than that by pulling the fuses we are looking for that drop this is how to locate the offending circuit.
when you find the offending circuit let me know for further assistance.
