ive put two brand new alternators on though? they cant both be dodgy can they?
ive rewired the blue wire straight from back of alternator to back of clocks too.
but with even this wire disconnected it still charges so i cant imagine it being this??

If it's two new alternators WITH new regulators then they are setup wrong.
The alternator created the power and the regulator regulates that power to the desired amount, i.e. not too much like what you have nor too little.
Blue wire is the field excitation wire and comes via the warning light, with this disconnected you should have no charge at all, unless you are revving the car fairly hard then checking?
Do you have the correct item fitted?

there are a set of bolt s for wires and also a plug for the leads. i have the red wires on bolts and blue wire via the plug? this wont be the reason will it? i mean i dont need to either use just the plug or just the bolts? and that alternator is correct isnt it?

[quote=martysmartie;5777921]It has to be a regulation problem, it's worth, as a test, fitting the regulator from the old one to the new, and then see what the outcome is.

Is your high voltage reading your getting at the battery or have you been checking onthe back of the alt,Also rectifier is common to go on the a127 but the fact you have two new ones fitted its seems hard to say

I wouldn't discount 2 faulty units. I did 3 in a row (QX Components IIRC). On each unit, the first time I went beyond 5.5k rpm the battery light came on and the alternator died. I replaced it with another branded unit and was fine ever after.

Do not use this one, it is for a rev. gauge. It is AC, not DC and will produce about 30 volts.
So both thick red wires on the one B+ M6 bolt!

You have the red wires on bolts (multiple)? You should only use the M6 (10mm spanner) bolt! This is the B+. The other bolt is the W (M5).
