Re: 6volt alt with a 8 volt battery
Probably not, or not very well. The regulator on a modern 6 volt alternator would probably sense the 8.5 volts at the battery and assume the battery was fully charged whether it was or not. A Model T generator will charge an 8 volt battery, since the T generator has no automatic voltage regulation, though it's not a very good idea. A modern 6 volt system will provide about 7.5 volts, and a modern system designed for an 8 volt battery will provide up to 9.5 to 10 volts. (If one exists) The best solution is to use a good 6 volt battery and a stock T generator with a modern voltage regulator added. If your starter is bad, fix it.
