    What is this Alternator

    The "real" part number is cast into the housing near the fake printed one. I see two wires. This early alternator can be run with either one or two wire regulators if the proper brushes are used. Repair parts are almost impossible to find now , so if bad, buy yourself a complete good one.

    Low output at idle w/ac on?

    Alternator should be putting out about 14.4, you are low. Do you have a square back alternator with electronic VR? This should work well at idle. Sometimes we can cheat a bit by turning up the idle a little.

    Elec woes, crank, no start after running then parked.

    In no particular order the things that I would suspect for an intermittent problem would be- ECU, resistor, coil.

    1974 Plymouth Duster Electrical Problems when hot

    You have either a bad battery or starter. Cranking voltage should never be below 10 volts. Check battery first. Charge battery fully. Load test battery, this simulates how the battery reacts to the starter running. If the voltage drops below 10v then the battery is failing under load. If the...

    Voltage limiter, 69 Dart

    The whole cluster gets 12v. The limiter knocks down the voltage to the gauges to 5v. Power up the cluster and the input to the limiter should be 12v while the output and voltage at the gauges should be 5v. This is true wether you have a standard dash or a rally dash. On a rally dash the limiter...

    Question on passenger stop light circuit

    A bad T/S is a common problem. Both brake lights must go through the T/S switch. While stepping on the brake pedal, try wiggling the T/S lever and see if it comes on.

    rebuilding an alt

    Many parts for rebuilding are not available. It is best to buy an alternator already rebuilt that has all the good parts in it and is guaranteed.

    Replacement battery

    Originally green and yellow caps were rated differently but were same outside dimensions. The red cap was higher rating and physically larger. Now- the difference between green and yellow caps are only the color of the caps. This allows me to select which color cap came originally on my car...

    I need some fuel sending unit experts please

    Random thoughts. The IVR in the gas gauge may be behaving inconsistently. Have you confirmed that the gauge cluster is grounded to the body? You may have two problems, fuel sending unit (chinesium) and temp sender ( taped threads?) I tend to think that your new fuel sender is bad because you can...
