my 87 has 295k miles & I have a battery drain which has become worse for the past 1 1/2 yrs...could it be in the ignition switch...seems to be intermittent

best bet use an IR gun to find the hot relay on your CE panel ,
remove the parcel tray and the top CE panel board so you can reach in with the window down,
use and IR gun to find the warm relay.
take the car for a 5 mile drive shoot the panel. note any warm areas,
then close the door.
wait 15 mins then come back and reshoot the panel with the door closed.

NOTE its also possible the alternator could be the culprit.
after testing the CE panel ,

Then disconnect the battery,
then jack up the front of the car so you can shoot the alternator.
let the engine cool overnight.
In the AM shoot the alternator note the temp
connect the battery,
start the engine let it run for about 30 seconds, shut it off.
let the car sit for 15 mins then check the alternator to see if its warm.
recheck the CE panel without opening the door

Thanks that sounds like the best solution...I had the alternator checked off the vehicle & it was OK per the tech who tested it....appreciate your response! Tom Taylor Bardstown, KY Bourbon Capital of the World........
