Those of you with the late 80's and early 90's models with power locks...do you notice that they energize when they battery is hooked up??? Mine make a noise, like the solenoids have been energized, when i attach the battery. I think that this is the drain on my battery - its a fairly good drain...after 4 hours or so its hard starting and overnight its basically dead.

Thanks in advance for the help!!!

Sounds like a bad relay or something on the door locks. Shouldn't be draining like that. Pull the fuse for them, see if the drain issue persists.

using a test light can really help you with battery drain, hook up a light and keep pulling fuses until the light goes out.

I've only noticed the solenoids on the seat belt..

don't know if a bad ground on that circuit would cause your problems,but on the left side of the driver's seat by the rocker panel there is a ground wire for the rear defroster/power door locks that corrodes due to a wet carpet problem,firewall leak,door seal,or other. that is on my 95 Z26,yours may not have this.so check!

also you can do what the previous poster says: disconnect your negative battery cable,with a test light,clip the test light to the negative terminal,and the other end to the disconnected battery negative end,if your light,lights,you have a drain,pull each fuse until the light goes out. you can even do the same with a volt meter and it will tell you how much current it is actually pulling.(set to DC scale 20 I believe.

I made a wire as shown in the video that 'themixer' posted...already tried the in-line amp reading on my multi-meter and fried the fuses and will be testing in the next couple of days. I'll post what I find here.
