ok, this is how it is. this afternoon i done some testing using my digital volt meter, i connected the meter to the battery and was getting 13.4v with the engine running, when the whirring noise from my alternator started i was getting 16.7v at the battery and when the noise ceased it went back down to 13v.
my alternator seems to be wired up wierd, this is how it is wired. i have one wire going to the nut terminal on the rear of the alternator which goes round the engine bay and in to the loom over on the drivers side. there is a white connector with two wires coming from it, one red and one white this plugs into the side of the alternator. the red wire goes to the same nut terminal on the rear as the othe wire and the white is not connected but has some sort of device built in line on it.
i tested, while the engine was running,the two spade connectors in the alternator on the side where the red and white wires connect to using the white plug. on the spade which the red wire would connect to i got no volts and on the other which the white wire would connect i got 0.05v.
by this time the whirring noise coming from the alternator was constant and pumping 16v into the battery. i pulled the white plug out of the alternator, the noise stopped and has not returned and i was getting 12.5v at the battery.
does this make any sence, do i leave the white plug pulled out, what is this connection for? the device that is wired in line on the white wire has the following label attached and reads.... INGERSOL RAND 120403-025,V#18558,59732305 002.
i am now confused but at least the alternator isn`t cooking my brand new battery.
bill.
