Battery drain/wiring help
Discussion
I didnt plug the car in last sunday so when I got home last night the battery was completely flat. So charged it up last night but decided I really need to look at it because what if I go away for a week or something!
So, with the meter plugged in the car is drawing 0.06-0.07A, on pulling fuse 14 (CIG lighter, radio, interior lights) this drops to 0.02A.
Ive put the fuse back in and unplugged the radio, CIG lighter, interior light relay, both lights are off and doors shut also. The meter is still reading 0.05-0.06A where else does that fuse go?
Cheers

Right, ive spotted some modification to the wire going to the foot well light.
On following it it leaches into a few other places then ends up ontop of the box behind the centre console, next to the clutch pedal. Access is awesome but i think its some kind of battery and a control box.
The car used to have a tracker years ago. Is this what's left? Wonder if its my drain.

Connected the meter and it was showing a 450ma drain straight away. Why didnt this show up last time!?
Started from the battery and the power goes 2 places. The 80A maxi fuse and the starter. Pulled the fuse and nothing changed. Disconnected the battery then disconnected the starter. Reconnected the meter and it was gone, down to 10ma. About to reconnect it all to make sure it comes back but looks like theres something wrong internally on the starter.
Maybe last the starter has to be in a certain orientation for it to show up, maybe it wasnt quite right last time.

Well my starter refurb man thinks theres nothing wrong with the starter and it was a coincidence that the drain disappeared when Itook the power cable off the starter.......3 times.
He says theres no way anything in the solinoid or starter can short to give a drain.
So do i just go back home and refit it and get the same test results and burn the car?

You could connect up the starter off the car- use a spare battery.
Trigger the solonoid- the motor might well jump about a bit so make sure it's secure.
Might show up a sticky solonoid.
Can't quite see how it would stick and give just a little drain.
Maybe it's the drive to the solonoid that's just slightly on.
Meter the drive to the solonoid, rather that the high current feed. I wonder if this comes direct from the key or thru the ECU or even alarm/imob? Anyone know?
second option (and I've not checked back thru this thread..) is the alternator wired back thru that route..? Try pulling the wire on that and see if the drain goes.

This is the wiring diagram.
With the main positive from the battery down to the starter connected there is a drain. When that one cable is removed where it meets the starter the drain drops to 0.01A. Thing is those main contacts in the starter should be open so there should be nowhere for the power to go!

The alternator and solonoid side both go through that 80A fuse and with that removed it makes no difference, just that main cable!

well you're right. For current to flow the solonoid has go be shut- but if it's shut then the motor would spin.
The only marginal option is that the solonoid is not releasing properly and is presenting a high-ish resistance that allows limited current flow.
It then might only be 'sticky' every so often.
If you find you have the drain, try t
tting the starter solonoid with a hammer and see if it goes away.
Again, this could probably all be tested off the car.

Found the issue. How I didnt have a catastrophic failure I dont know. The power cable has worn against the gearbox so cenneted to the starter it was leaking power, when I disconnected from the starter I pulled it away from the box and therefore stopping it leaking!!
So need to find somewhere to make me one up now or do you think they'll be cheap enough from SWLC??
