Has anyone run across this? Have a '55 with the stock 6v system; on hot days, it wont start after running it - acts like it is not getting enough power to turn over (turns over slower). Will start hot with a jump. Thought it was the battery, then the generator not charging, but both proved to be good. Thought the cables might be bad/corroded, but the consistency (of not starting only when hot) does not fit the conditions. A good buddy told me that the old starters, b/c they are near the exhaust, get hot and the armature 'swells' causing it to turn slower, requiring more amps to turn over fast enough to start the car. - hence why it will start with a jump. Waited for the car to cool down, and sure enough, starts right up. Checked the amp draw at cold start and it was just at 5/6 amps. Have not tried the same when hot., but suspect that it will dip into the 4 amp range. Going to have it rebuilt, but just wanted to see if this is common or just a random fluke. Thank you.
