93 escort battery drain
#11
I believe the cable from the positive post on the battery goes to one of the terminals on the starter relay.
This is what I want you to try OK?
Take the negative cable off the battery terminal.
Remove the cable from the battery that goes to the starter relay and cover the end so it cannot contact any metal.
Now reconnect the negative terminal to the negative post on the battery.
Connect your voltmeter to the battery terminals and see what the voltmeter does.
Give it a few minutes, if the voltage does not drop there is a possible problem at the relay or something the wires there feed. Disconnect the negative cable again and reattach the cable to the relay and now remove the heavy wire from the alternator and do the same test and see what the voltmeter does. Be waiting for your reply.
What we're trying to do is isolate the drain. It has to be a big one to pull the battery down that fast ,,,,UNLESS,,, the battery is the problem.
The metal substituting for the hi current fuse tells us there is a reason that was done.

Be careful there.
First,the "gunk" may be dielectric grease to prevent corrosion at those terminals.
Second, the output from the alternator goes through the heavier wire connected to a separate post on the alt.
If what you found solves the problem, great!

Dang the guy didn’t even come back and thank u for ur help and whether he got the problem solved! I’m guessing the problem was fixed. I just read this whole thread because my battery has a slow drain when it’s turned off I’m gonna make a new thread though about my issue thanks for taking the time to help that guy back in 2013
