A common myth in relation to collector cars is the idea that 6-volt electrical systems are in some way inferior to 12-volts. Some hobbyists convert their cars to 12-volts, switching to alternators, complex batches of resistors on stock items like gauges and orginal radios. Of course all light bulbs have to be switched so they won't instantly blow.

Obviously, if you are driving a highly modified car with contemporary stereos, halogen lights and CD ignition, than 12-volts may be necessary.

However, if you have a basic stock, 6-volt car (most likely built before 1956), the truth is that you do not need to make the change. If your old car is suffering from slow starts, dim lights or worse, the 6-volt electrical system is not to blame.

Start with the battery. This may sound condescending but in using a battery tester to check the batteries power, make sure you are using one with a 6-volt/12-volt option. Too many guys have thrown out a good 6-volt battery after using a 12-volt tester.

If the battery is bad or weak, purchase a fresh one from either your local auto parts store or a company that specializes in the original looking tar top script batteries.

Make sure your battery cable terminals are clean and clamp securely to the battery.

If the car still is slow cranking, the next most likely place to look is the starter. Remove the unit and take it to a specialist in your community that tests and rebuild starters and generators. These guys are still around and often will check out your unit and rebuilt it as needed for around $30-35 or less.

Go through most of your wiring, connections and test your generator for out put as well.

Make sure you have a fresh, tight generator belt as well. It has been our experience that when everything in your electric system is A-OK your 6-volt car will start and perform as good as a 12-volt car.

If you have other symptoms such as slow starts only when hot, or only when cold, you may want to take a look at the engine itself.
