What does it mean when D5 dims while you are driving,i noticed that today right after doing about 125mph,i found it weird that when it shifted from 3 to 4 it didn't have that much juice to keep pulling and it was building up speed a little slower than usual,that's
when i noticed the D5 dimmed,got stonger and dimmed again,any clues???

When you posted, was it with the intent that people question your common sense?

 

too much power goin to ur engine thats y your d5 light got dimmed. it needed the juice of the lighted d5 to continue going at high speeds.

 

does this affect all lighting/electrical? im just curious about headlights and tails as i just put in a sub and it dims here and there and now im contemplating a cap.

 

then what's the alternator for?
