    Voltage Regulator/Rectifier Fix

    After the effort of taking the voltage regulator / rectifier out a 1995 SLT 750 Polaris I investigated the circuit path from Stater to Rectifier . First of all inspect the wiring for any pinched or burned wires . Any one of the Yellow wires from the Stater leading back to the Control Box can cause problems . Any of the other wires from the Stater can also cause other problems .
    In my next I will explain in detail how the Rectifier/Regulator works with pictures and technical explanations of parts and circuit schematics . This will help you fix your issue with battery not charging .
    Look for my next post January 10th though 14th .

    This my homemade schematic of circuit components relating to the voltage regulator / rectifier on a 1995 Polaris SLT 750 . Use heatgun to soften epoxy resin . Use grinder to cut plastic case away from circuit board . Good luck . Hope this helps .048.jpg

    Re: Voltage Regulator/Rectifier Fix

    Hello once again . Once the plastic case has been removed use a heat gun to soften the epoxy resin and be careful while picking the soft resin away from circuit components . The main reason why there was a plastic case with resin around the components was for proprietary reasons mainly . After any bad solder joints are repaired which is usually the yellow wire or the 47K resistor joint I see no need to epoxy any components in place the way you took it apart . Be sure and use a good grade of solder such as 60 / 40 rosin core and not the soft solder like the factory used . Each connection through this circuit is very important so examine each solder joint carefully . Good luck . Cheers

    OK , sorry . The unmarked diode in the center of the circuit board is a common silicon diode . It keeps the current flowing in one path .

    Re: Voltage Regulator/Rectifier Fix

    Hi again , personally I see no need to cover any of this circuit with epoxy or any other covering . The regulator / rectifier is inside of the CDI box and is waterproof . With no epoxy on the components allows them to cool much quicker and should make the regulator / rectifier last much longer . Good luck to everyone .
