    If the alternator output voltage is lower than 13.8 -14.5V, then you may have a case of a short in the alternator. Also, in case of a short in the alternator, the output current will be lower than expected for a given rpm. This can be checked at an auto shop with testing equipment. #2. Battery drain. If an alternator has a short circuit, it can ...

    ADVERTISEMENTS: In abnormal operation, the alternator may be subjected to transient conditions which cannot be explained from steady-state theory. These transients may occur from- (i) Switching (ii) Sudden changes of load, (iii) Sudden short circuit (either line-to-line or line-to-neutral or from a symmetrical short circuit). These short circuits may develop severe …

    The short circuit ratio (SCR) of a synchronous machine is defined as the ratio of the field current required to generate rated voltage on an open circuit to the field current required to circulate rated armature current on short circuit. SCR means a short circuit ratio. The typical value of SCR for modern alternators is 0.5.

    a 300% short circuit current is no more a ‘given’ than it is likely that the connected electrical loads will result in the alternator operating at only 0.8pf lag. Multiplying factors. The intent of a Short Circuit Decrement Curve is to provide information regarding the performance of an alternator under fault conditions.

    The alternator will be fine. The circuit would have been directly from the battery positive (because that is where the positive form the alternator connects too) through your spanner to the carcass, to the engine block then to the battery negative. the current will have flown outside the alternator through its carcass, not through its internal components or …
