Turn signal, brake light, blinker issues

I have a 69 SS396 Chevelle 4sp car and with the engine running if I turn on the lights, blinker, turn signal or put it in reverse the engine cuts out for a split second and then runs crappy. Turn off what I turned on or put it in a forward gear runs great. Not even sure where to start and any help would be great.

Re: Turn signal, brake light, blinker issues

what are you running for a distributor and/or ignition box??
where is it's power coming from?? the fuse box, or original resistor wire in harness??

Re: Turn signal, brake light, blinker issues

You're going to have to check a number of things first.

Does it do this every time you put it in reverse regardless of lights or not? (engine vs. electrical issues).

What is the shape of the wiring? Factory original, un-touched? Factory "modified" by a previous person? Aftermarket? In shambles?

As stated above let us know what ignition set-up you have and HOW it's wired. One possible cause is the main bulkhead connector that links the underhood wiring to the interior is loose/dirty/corroded and the main Battery power feed doesn't have a good connection, extra loads are causing a large voltage drop and then your car electrical circuits suffer due to this poor connection.

Sorry for the lack of info but I figured it out. Right before I put the car away for the winter last year I put a MSD distributer in it and hooked the power wire to the wrong spot affecting all my lighting. Hooked power to proper spot and car runs good lighting issues gone.

I could see myself doing this.
