Alternator Not Charging

[Mark-R33]

hi all,

the other day as i was driving to work, i noticed that my cluster looked a bit dim, then a warning signal from my turbo timer was displaying that i was only running 9.2 volts. got it to work and called RACV to look at it....

the RACV dood said that the alternators fine, but what the prob is the battery light in the cluster is blown and it wont allow the alt. to charge up the battery, i hav never heard of this prob and am still not sure that this is the case, just wondering if ne1 has experienced nething along these lines, or heard of the same thing????

NOTE:

- just tested the bulb in the cluster and isnt blown

- is a brand new battery but cheapo brand

can any1 help me?

thanx heaps,

Mark

yep. if the charge light bulb blows you dont get charge.

ie.. it completes a circuit to the altinator to energise the voltage regulator.....

hmmm. you may have blown a fuse

to test it you may have to aply battery voltage to the alternator regulator feed. im not 100 percent on wich one of the two it is. (two pin plug on the alternator)

just use a test light with the aligator clip end on the car jump start points. (next to the engine bay fuse box)

and probe each terminal. youl here a whine when the alternator energises and it will start charging.

if it doesnt it is a shagged alternator.

thanx man, is it possible that it cant supply a charge back to the battery if the battery size is 2 small, especially when lights, demister, cd play, etc is on? the battery is tiny and has 320(something) on it?
