The needle is moving to the right (+) when you turn on the switch because it is wired in reverse. Return it to the way you had it before. It is showing the same thing when running because it isn't charging or something is wired wrong or it isn't running fast enough. It really doesn't matter which way it moves, it is just a matter of which way it is wired. It should move one way when turned on and the other when running if it is a (-0+) type.

You haven't given enough information about the type of alternator. If it is a one wire you probably haven't increased the rpm enough to kick it into the charging mode. If it is a three wire it is a bit more complicated to wire properly.

Don't trust the alt light. (It is supposed to be off with the engine running.) With the engine running check the voltage at the battery with an analog (Needle) voltmeter, not a digital. It will show 13-15 volts if it is charging and if it is a one wire you must increased the rpm considerably to get it started charging.

It was a fairly typical Northern Ireland farm where the main enterprise was dairying but some pigs, poultry and sheep were also kept. Potatoes were grown for sale and oats were grown to be used for cattle and horse feeding. Up to about 1958 the dairy cows were fed hay with some turnips and after that grass silage was the main winter feed. That same year was the last in which flax was grown on the farm. Flax provided the fibre which w ... [Read Article]
