I grew up just over ther hill from where President Nixon was born in Whittier, Caifornia. As a kid growing up in the 50s and 60s it wasn't uncommon to spot Richard Millhouse Nixon driving his dad's 55 Ford pickup down Highway 39 with a blonde...
When folks would see our future President driving the '55 around town at night they always used to say "that boy's lights are real dim." They didn't mean that the young Nixon lad was an idiot, they really meant that the lights on his 55 Ford F-100 weren't real bright. The reason, and here's where this blog turns into a handy tech-tip is the electrial system on '55 Fords were 6-volt, Positve ground. In 1956 the Ford Motor Company went to 12-volt. Negative ground. If anyone wants to know more on this subject and how to convert from a Positve to Negative ground system on their truck leave a comment to this blog, and I'll jump back on here with more vital facts and information.
