Hi all,
My dad's SC is an '89 and he's been trying to track down a voltage drain issue. Pulling out every fuse in the box under the hood and putting them back in one by one, he's pretty much determined the culprit is either the IRCM\CCRM, ( anyone know what the 'real' name of this dang thing is? ), or one of the components downstream that it controls.
Now here's the weird thing... the last voltage check of the night showed 10.93 volts on the battery... however, sometime during the night, ( as the battery slowly drained ), the fan came on! It was running this morning when he went out to check, and, the battery was down to 3.09 volts ... so the fan had obviously been running and drained it pretty well. Anticipating a couple of questions...
Has anyone ever heard of or experienced this problem?
Why would the fan remain OFF at 12, 11, 10.x vots... but automagically turn itself on at some lower voltage?
I'm 'assuming' this is an issue... but if not, then that's one heck of a crummy design on Ford's part... I would think? Unless someone knows of a good reason it would be designed in this way?
Any help \ thoughts are most appreciated!
Thanks,

- No, the ignition was NOT in the run, ( nor in the on ), position, it was in the OFF position... in fact, the keys are hanging up in the house.
- Every fuse had been put back in, there was no drain at all with only the IRCM\CCRM fuse removed. This was the last fuse he put back in, which resulted in a slow, steady battery drain.
