    Exclamation Regulator Resistances

    In response to my previous thread regarding battery voltage , i removed the rectifier today and checked the resistances as per the manual, diodes read correct except for resistance was not 0.43 to o.51 it was 256 ohms. spoke with the dealer and he suggested charging the new battery fully which i have not done and then see what charge i get out . at moment it is only 12.6 volts not 14 volts. he did say if its not running the battrey flat dont worry about it. any advise/ help would be grateful. he said as long as im getting 12 volts from a 12 volt battery its not worth replacing it as it wont do any harm.

    If you want to compare to the values in the service manual, you'll need a multimeter capable of checking a diode. Look at the picture in the service manual so you'll know what the "diode check" symbol looks like to verify if your multimeter has the function. Using an ohmmeter only tells you which way a diode conducts, the resistance value it returns is meaningless.

    when checking one way it is open circuit as the manual says but i get your point. i have another meter i'll check if that has diode check. im not sure if the output voltage from the stator is correct, the pick up resistance is correct. is the stator output ac or dc . im thinking its ac else why the rectifier.

    would my stator voltage be wrong tho if the regulator has gone.

    The unit is a regulator/ rectifier it controles voltage as will as converts ac stator current to DC battery current. replaces this part and re test I supect it is bad. Tommy Jordan

    thanks tommy, im certain its faulty as the pick up resistance is correct and i suspected it would be ac else no point rectifying it to dc. if the stator had gone down it would show a high resistance and it doesn't. as stated rectifier is showing 260 ish ohms not 0.43.
