[urq] Battery drain

[Peter Golledge]

I've used a meter set to measure current and placed it "in line" between the
positive terminal on the battery and the positive lead.  I would expect some
draw of the order of milliamps if all is well.  Do ensure you don't switch
the key to run while the meter is inline, it sure wont like it and will blow
its internal fuse (if you are lucky).

Subject: Battery drain


Well one of my worst nightmares has apparently come to pass.
My battery goes flat after ~ 12 hours. I had the battery checked this
morning and they said it needed a charge but was not the problem. I'm not
totally convinced by their testing method, but whatever.
I remember seeing a post about taking the battery post off, and checking the
power drain across the post and cable with a DVM with everything turned off,
then pulling fuses 1 at a time till you find the culprit. Is this the method
of choice? Am I right that you measure across the disconnected cable and the
post for voltage drain? What is considered normal here for clock, ecu,
radio, and misc "maintenance".
I'm seeing 11.7 volts across here which tells me something is _way_ wrong
and not a small short to ground. More like leaving the lights on all day?
Dang - I _hate_ electrical short issues!! I would rather have a mouth full
of root canals than deal with this!!  
Patient is an 83 URQ with a 3B motor transplant.
Help!!
