Another common failure could be the startermotor itself or the relais on the starter is going south or a bad connection on the red cable running from the battery + to the starter. This also would cause the symptoms you discribed. If you can't find a drain from the battery check these.

Turn the control round till it reaches 20v
It should be on the V- which indicates direct voltage not alternating.

If you put the multimeter on to the battery pos to pos and neg to neg the battery should read over 12 volts. If reading over 12 volts the battery is not the fault.
Best of luck

I got home at 5:15pm and locked the car which is immboliser and siren etc etc.

Ive just tested the battery and it was reading 12.02V which im guessing is "OK" ish but we/I do not know as of yet how much current is been drawn.


Started the car and the battery was reading 14.25v and did increase a bit when I increased the throttle.

How do I now check the current been drawn?

So I just set the meter to 10A and then put the black one on the neg on the battery and the red on the earth strap going under the battery?

I would say that the battery showing 12.02V just after a run is too low. Car batteries are not actually a 12.0V source, they are around 12.6V depending on temperature.

this website is very in depth. Click through the links for the FAQ (7.1) and then click on section 4 - how do I test a battery. You will find a table in there, showing you the open circuit voltage, and how this corresponds to the state of your battery. 12.02V corresponds with about 25% state of charge - which is bad (obviously).


To test the current being drawn (with everything off) turn the dial to the 10A DC position - circled in green and plug the left lead in to the 10A socket - also circled. With everything off, touch the red lead with the multimeter to bare metal earthed with the body, black to battery negative. This will let you know how much current is being drained.

I warn you now - if there is something seriously wrong with a piece of eleccy kit on your car, and it is pulling more than 10A when you test, it may well smoke your new multimeter.

I would also suggest you check in the manual that the symbols I have circled correlate correctly with what I have said, rather than just listening to what I have said, (and then hoping I buy you an early birthday present - I am skint at the moment and I have not used that type of multimeter before).
