Searching for Battery Drains when key is off.
Found this great little method for finding circuits in your car that may be the cause of Battery Drain whilst the car is off and parked away.
I have been a Sparky 27 years and i had never seen this method before, it may not be news to some, but it was to me.
The only method i knew was using the Multimeter in mA scale placing it in-between the battery terminal and lead to measure the over all vehicle draw when not in use.
Then trying to trace it down from there, using the same method on individual circuits.

Handy hint, but those meter probes, crikey. How on earth he doesn't manage to short + to chassis with that much bare probe I'll never know.
I just use my clamp meter.
If a man says something in a forest and there is no woman there to hear it, will that which has been said still be wrong?
Some people are like clouds. When they go away its a beautiful day.
Hmm, new to me, makes sense though
It nonsense, proof is hes testing it on a Corolla, everyone knows nothing ever goes wrong with them.
Jokes aside, i missed this thread, info absorbed and noted, a very good way to detect current draw when the car is off that id never known of.
Yep, knew that.
My 1974 Mazda 929 used the fusible link as a shunt to provide a voltage for the in dash centre zero millivoltmeter, thereby displaying current draw to/from the battery.
(All connections, including the alternator, but not the starter motor, were made south of the battery.)
Never stand under a shadow that's getting bigger
Yep, a handy way to do it too, especially if your clamp meter isn't that sensetive.
Here's some charts to use to convert the millivolt reading to milliamps current drain too. For various types of auto fuses.
