First time poster here!

When I drive my car it occasionally starts flippin' out.

My volt meter jumps all over the place. My tach starts jumping also. All the lights (interior and exterior) start flickering. Sometimes it will go away and sometimes it will stay that way?

I had Kragen run all tests on the battery (battery is good). I checked all the wires and grounds. Everything checks out okay.

This happened on my old motor. I rebuilt the motor and installed a new one-wire alternator and I also replaced the Summit HEI distributor with an Accel HEI distributor. Still having the same problem.

While this flickering occurs it seems like it doesn't charge the battery either. My battery will run down (only when the flickering is occuring).

Help!

 

You need to provide basic info about your car:
-year
-model
-engine
-trans
-any major mods

Without that info, we aren't going to be able to reliably offer suggestions regarding the possible causes.

Also doesn't sound like a "fuel and ignition" problem, so it might be beneficial to move this to "General F-Body Tech & Info".

Let us know what vehicle/engine combo you are asking about.

 

1968 Camaro Coupe
383 Stroker
670 CFM Holley Carb (4 barrel)
Performer RPM Air Gap Intake
Accel HEI Distributor
Be Cool Radiator with dual electric fans
March Front runner kit with Sanden AC Compressor
TH-350 with 3200 Stall

The entire car looks fairly stock. The motor and all components under the hood are brand new. I disconnected the voltage regulator as I now have a one-wire alternator. I am not sure if there is anything else that needs to be done with the wiring as it is all stock. Everything else works perfect. It just started acting up one day.

I posted it here as it is an electrical problem and may have to do with the ignition as I have trouble starting the vehicle sometimes and the battery drains when I am experiencing the erratic voltage spikes.
