Howdy, my name is brent, I bought an april 1986 rx-7 last spring(love it). Having drove it last summer without problems (except some electrical problems in dash) I threw a fan belt on a trip, trailered it home, and left it sit till spring. I replaced the fan belts, treated her to a new battery, 1/2 gallon of antifreeze, and fired it up yesterday and now I get three beeps constantly while driving without any corresponding dash lights.(they may be out but some have worked in past ) They start in as soon as the key is on, cold or hot and sound continuously. Any help would be appreciated. As far as the electrical problems previous, the temp, volt, and oil pressure gauges never showed a reading, the radio wich worked at first started smoking and quit and the climate controls only work if you hit a bump the right way, however all other controls work and I have seen appropriate warning lights in dash.

 

The buzzer is caused by three things:

1. Redline RPM
2. Low Coolant
3. Low Oil, this sometimes turns on when turning right when the oil sloshes to the non sensor side of the pan.

 

Warning beeps are covered in the FAQ: https://www.rx7club.com/showthread.p...72#post5131072.
