Robin,

Isn't that an 8060a true RMS?

Nizzzzze!

(I'm gonna' guess the Fluke is closer. )

Figured it out!!!

So I picked up a multimeter and checked the current while pulling all the fuses. No change. So i still didnt have a clue. Just for the hell of it went to Advance and had them run a diagnostic. Sure as ****, the alternator was only kicking out 12.7V. The guys at O'Reillys were wrong. So i finally picked one up today and replaced it. So far so good, we'll see for sure after she sits over night. Thanks again for all the help guys!!!

Do a load test with all accessories on.
A voltage of less than 13 volts is too low at idle.
the amperage needs to be at the upper range of the rated capacity when under load.
You are killing the batteries with the constant deep draw down.
When I'm right I'm right!

For years I carried an 8020a in my briefcase. Don't have it any more.

Nowadays, I've got an 8024b and an 8062a (nice display), but an 8021b is my "daily driver". I always wanted an 8060a, but the 8062 does a nice job when I need true RMS.

Can't help it, the 8000-series are still my favorite hand-held DVMs.

EDIT: Glad you brought this back up. Tonight I looked at the two I seldom use and found that familiar "BT" in the upper left-hand corner of both their displays. Got 'em changed before they leaked or sumptin' worse!

I only have 1 working 8060A. The other one took a nose-dive off a 12' ladder onto a concrete floor, but still has some usable parts.

I hate it when I forget to turn it off, but I always have a god supply of 9 volt batts. I change out the batts in all the smoke detectors on a regular basis and most still read 9 volts. They make good spares.

Smile Fixed - Parasitic 2005 Expedition - Cause = Rear wiper motor

After a year of looking, testing, disconnecting the battery, jump starting it twice a day we finally found the source of the draw!

It was the rear wiper motor it was a huge draw, probably trying to park constantly. I disconnected it and haven't had ANY battery issues since (over a year)

Thought I should post in case anyone else has the same issue.

Related: You can't just unplug the connection to the motor because there is a tie to the front washer pump. I had to cut the motor wire.

Smile Got lucky :)

"How did you ever figure that out?"

My wife had a "didn't the rear wiper stop working about that time?" revelation about the timing of when things started to go south. Put the amp meter on the motor and saw it drawing, pulled the plug and the draw stopped.
