1994 RX-7, 3 Year Old Battery, Infrequently driven vehicle

Driving to store last night to charge up the battery the seat belt light and buzzer came on intermittently after a few miles of driving. I fastened my seat belt and all was well and I chalked it up to the cold weather and a sticky sensor.
Got home and parked the car in the garage. Here is where it gets bizarre.

I went back in the garage and noticed the parking lights were flashing intermittently. They then stopped and I went back inside a little puzzled. I went back a couple of times and witnessed the same behavior. They would flash weakly, the rear brighter than the front a few times then stop. I engaged the 4-way flashers and they flashed properly then I disengaged them and everything seemed fine. I rechecked a few times and they no longer appeared to be mysteriously flashing.

About an hour later I hear the horn going off! I rush to the garage and not only is the horn blaring but the headlights popped up and were on! Just the headlights, no taillights. I popped the hood and after a few seconds the headlights shut off and retracted and then the horn stopped. Now I am really puzzled. I went to look for the owners manual to identify some fuzes to pull and then the horn went off again. I rushed back to the garage and the headlights came on as I walked into the garage and then the high beams began to flash!

At this point I pulled the battery cable.

I have never had any problems with this car. It is garage kept. There was just a little corrosion on the battery. My wife passed away a year ago and I did start dating again. Yikes!

Anyone have any ideas at all?

 

CPU #2 getting funky. It does this when the battery is low. Have your battery tested and clean the terminals and leads.

 

Thanks. I suspected battery though the car started right up with absolutely no problem. No indication the battery was failing. Plus, I have had batteries go in the past and have never experienced these kinds of weird symptoms.

If it is just the battery I will count my blessings. Electrical problems usually spell big $$$$!

Thanks again.

 

i want to revive this thread becuase im having similar trouble...was thare any closure here?

 

Headlights up and down with horn going off is the car alarm. Could be poor grounding, or bad connections b through the doors that go to the switch's the alarm monitors, just have to start eliminating theings one at a time.
