It appears that the problem is coming from the factory alarm system. There’s just a lot of odd things going on that makes me tend to think it’s the factory alarm. First of all, when I locked the car in the prescribed way, which is supposed to arm the alarm, nothing happens when I “break in” to...

Thanks HH. I’ll look into getting an FSM.

Update: I’m not going to take the car to a mechanic. I’m going to take it to an Exocist! I fiddled with it last night suspecting that it might be the anti-theft system since it was drawing so many Amps (11 Amps). Along with that, the horn wasn’t honking consistently. It only honked...

HH thanks. When you refer to the car running better with the kill switch being turned off, do you mean the kill switch removed?

Hot Rod Roy, apparently I misunderstood your instructions. I’ll read them again and try your suggestion. Thanks for trying.

Hcbph thanks for the info.

I’ll disconnect the alternator too

LLC5. You may have hit it on the head. I have an aftermarket amplifier AND the other day, I set up the car to test the alarm (unrelated to the current detective work) and when I triggered the alarm, it didn’t sound off (horn). I’ll check those two items first then find out if there are any...

LLC5. Test results for parasitic draw: Sit down, fasten your seat belt. 11 Amps ! Not ma. Amps! It probably takes that many Amps to turn the starter.

LLC5, thanks. I’ll look into parasitic draw. By the way, it’s an 85 not a newer one.

LLC5 I’ll try to condense the information so you don’t have to read a long story. First night: dead battery. The battery wouldn’t hold a charge. It kept charging at 3 Amps overnight and the charger gauge never went down to its usual 1 Amp. Installed a new fresh battery. Dead the next morning...

Hot Rod Roy. I tested it the way you described. Light bulb with aligator clips. Connecting it to the positive and negative poles on the battery, the light goes on. Disconnecting the alligator clip from the negative pole and attaching the volt meter to the positive pole and the disconnected end...

Hot Rod Roy, thanks. I’ll try that tomorrow. I already have the light bulb and probes that I put together to watch the bulb while I pulled fuses. I’ll give it a try.

Hot Rod Roy. I just checked it with the volt meter. With the "kill switch" "on", it's measuring 0. With the "kill switch" "off" it's measuring 11.5 V.

First, please allow me to apologize for my missed description of how I was testing the circuit. I'm sorry if I misled anyone. My first description was unintentionally misleading. I will describe it accurately this time after having contacted my neighbor who originally showed me what to do...

1985 C4. This is a weird one. After replacing my dead battery with a new one, I came out the next morning and the new battery was dead. I figured that there must be an unknown drain in the system even when the ignition is turned off, so I replaced the new-dead battery with another new battery...

Thanks Hot Rod Roy. It's been so hot here in CA that I haven't started to disassemble anything, although, when I tapped on the sensor which is located on the right side of the engine head, the fan motor shut off but came back on within a minute, with the engine temperature still low. Once...

Hot Rod Roy, sorry. I didn't mean to hi-jack the thread. I did start a thread in September so if you want to answer my question, here is the link: Again, really didn't mean to hi-jack this thread or change the subject of discussion...

Something is definitely goofy with the fan sending unit system. Now it comes on at 150 degrees and sometimes even when the engine is cold and the first start of the day. I think something is stuck in the "on" or "contact" position. Rather than start replacing parts one at a time, I'm just...

Thank you. My problem is that when the fan comes on at 204 degrees it doesn't shut off like it used to at 196 degrees. I suppose a "sticky" relay could cause the contacts to stay closed, like the points on old style distributors. Another thing to check. I'm glad this is my "fun" car. One I...
