[QUOTE="Stalin-ohaulic, post: 6537407, member: 585517"] Several people said this and it's mainly false. Do you think the cap is afraid of the dark so it won't charge unless there is light? The lamp (light bulb) lights up when current is drawn through it. It goes out when there is not enough current being drawn through it to keep it lit up. What is this for? It's an in-line resistor. A capacitor will draw almost infinite current when it is discharged. This is similar to a dead short and should pop your fuse if it's completely dead and you just hook it up. This is the sole purpose of the bulb but when it dims or goes out you know the cap is basically charged and ready to be hooked up. WITH ALL OF THAT SAID, even though you guys didn't know it... you were right in what you said. Chances are the cap went into protect because there was no resistance in the charging line and it went into overcurrent protection so it wouldn't cause damage to the electrical system by either blowing up the alt, burning up the wire or popping the fuses.
