Ok on my way home from work tonight it was cold so i ran my heater for the first time. All seemed well so i go out later and start my ca and i was greated by a weird tach and three red lights {oil gen and water} the tach seems to just be reading volts it will hold at 6k when at idle and when im driveing it will go as high as 8k all seems well while driveing and my car started right back after about a 20 min drive so there seems to be no chargeing issues oil and water are fine also so if any1 has aany insight i would love to hear it ty in advance for any replys

 

Ok i finaly got it all figured out after a while with my dvom it was the alt man thoes things do sum funky **** to an rx-7 when they go out

 

Very considerate of you to post your diagnosis!, even though no one could help you.

 

well i figured if no one knew it would only be right of me to try to give insight for future questions of the same type now if any1 has questions about brakes exaust or suspension feel free to ask, I'm a mechanic and may have answers.
New to rotary but I work boinger motors all day!!
