PROBLEM: Battery light flickers and comes on at high revs???

[Blue_Joe 0]

Wierd one and don't know if it is a serious issue or not????

 

The battery light flickers on when I get into the higher rev range sort of 4000 and above. Don't have a clue what could be causing it. If the revs drop then the light goes out!!!!

 

Any ideas?????

could be your alternator on its way out

Could also be alternator belt slip at high revs ...

Well the Alternator has just been rebuilt using all new parts, the only thing not replaced was the casing!!!

 

Doubt the belt is slipping as it's toothed!!!

 

Would it have to be at alternator or could it be the battery not up to it? I always used to have an Optima Red Top but since that went pop I put an normal style battery on it. Albeit a 65Ah one where the Red Top was a 50, but I appreciate the Red Top is afar better battery!

 

Also I have found a slight voltage drop in the system - that seems to be caused by the battery to body earth strap!

More likely it's the voltage output regulator on the alternator.

Doubt it's related to the battery, since the red light comes on/off based on the feed from the alternator ..

Voltage drop? Get the voltmeter out ... ;)

could it be anything to do with vibrations effecting connections to earth or alternator??
