My 1952 Chev has very weak rapid flashing signal lights. I have a new wiring harness, new turn signal switch, and new 6V flasher. I've added a ground to the car body and checked the ground on all 4 corners. Any suggestions I could try would be most appreciated.

Is it a mechanical flasher? If its is the bulbs could be drawing to much current.

Hi Andy:
Thanks for your response to my dillema. I have two questions for you:
How do I know what type of flasher I have?( eg mechanical)

Is there some bulb change I could make to reduce the current draw?
Thanks again for any help you can give me.

Check where the bulbs were made. If it says Mexico get some new ones by GE or Sylvania(osram). I had a similar problem and changed the bulbs and eliminated the problem. Most mechanical flashers have a metal housing while the newer electronic ones may have a clear plastic one and are usually marked as such. I have not heard of mechanical flashers being a problem as thats what was used when the cars were new. Also if the car was recently painted be sure the mounting of the lamps has good contact with the body sheetmetal.
