[s-cars] Current draw/dead battery "a short story"

[Jim Furdyn]

Thanks for info Tom and I appreciate your recommendations. I have checked
the voltage at the alternator and at the battery for comparison, they were
less than a half a volt difference and this was one of the first things I
checked. All connectors at the alternator and starter were secure and in
good condition. Since this relay is not the mechanical type that you can
actually hear open and closing, this was not easy to spot. As previously
stated in an earlier post, I unplugged the aux coolant pump and waited until
the next day. The battery still went to less than 10 volts. I then started
to dig deeper into that circuit and found the smelly coolant pump relay.
This does not mean that I still do not have a possible bad TC temp sensor
feeding the relay a false signal and the relay staying closed therefore
draining most of the battery voltage. I have the TC temp sensor coming and
will install that first. This aux coolant relay smells fried but looks good.
I don't have to be a rocket scientist to say that I no longer trust its
functionality so I will be replacing this as well. None of this is any
guarantee that this problem is cured. If this does hold a charge over my
upcoming long weekend, I'll call it good at that point.
