Chevelle lost all power while driving, later regained power after sitting.
Background:
1970 Chevelle 383 SBC w/ longtube headers 200-4R Tranny Electric Fans connected to a 170* Thermostatic Relay sensor Stereo Amplifer in the trunk Retrosound Radio AAW Classic Update Wiring Harness I rarely drive the car and it has left me stranded probably 7-8 times out of the possible 20 times I have driven it. RECENT: I recently took it to a stereo shop to have my Retrosound replaced and some amp wiring re done. On my way home I noticed that at a stoplight with my left blinker switched ON that my tach was at 1200 RPM and then dropping to ZERO(back and forth) with no audible fluctuation of the engine (false indication). I turned the blinker off and it didn't do it again. Right after that the light turned green and I proceeded. About 30 seconds later my dash lights shut off and I notice that I'm just "gliding", the car shut off on me. I quickly put it in Neutral while rolling to attempt to restart it with no luck, the car had lost all power. When stopped all lights came back on but when I turned the key there was absolutely nothing, no sounds, etc. My wife came and got in the car while I pushed her for about 200 feet. Once she put it in Park, I attempted to start it, it then started cranking, and gave it gas and it finally started. Why ALL THE SUDDEN did it start cranking once the car rolled for a little while?? I have sense checked, and cleaned up all interior wiring, engine bay wiring, rebuilt the distributor with a new coil and module from Accel...Also re set the timing. Test drove it and acted great for 20 mins and then when I got home it died on me in the driver like it did originally. The ignition switch is original to the steering column which is from 1970. What do you think about the starter solenoid? If it overheats can you lose all power like that? I cant drive this thing cause Im afraid I will be stranded. PLEASE HELP! |

Something similar happened to me. It was the ground strap on the firewall. It was not fastened properly and it arched against the engine block at high speeds causing the engine to stall. It was a 69 Malibu. Hope this helps.

A friend of mine had a Camaro that used to do this. He took it to many different garages with no avail. I read up on it and told him it might be his coil. When it heats up the coil screws up inside. We were out together and it happened. We got a cup of cold water and poured it on the coil and the car started right up. He replaced the coil and never had any more problems.

Because the engine stalls and all power is lost I would suspect a problem with the positive power side of the wiring not the negative or grounds. Not sure how different the AAW wiring is from original. Original +12 comes from pigtail off positive battery cable, through a fusible link to a junction block mounted on the rad core support behind the battery. From there to the driver's side to the main splice. From there to the horn relay, through another fusible link then to the bulkhead connector to the fuse block. You need a meter or test light to determine where you have power and where you don't when you lose all power. Below is diagram of the original wiring, you can check all connection points to make sure they're clean and secure. |

Hank, wow. I am glad that there are members like you who have an answer, and explain it so even someone like me can understand it.

Seems like someone got jerked around on another Chevelle site.
