Thread: 300TDI in Disco 1 Alternator issue

What i want to know is the one thats in the vehicle died and i'm looking to replace it with any altertenative. I heard that there are issues with noise out of the alternators just wondering if i can get a BOSCH to fit then would it be fine with the electrics etc??

The only thing the Bosch alternator will need (except if you have an XE-XF Falcon type, they have this connection already) is for you to open it up and solder a piece of wire to one of the three stator solder joints. You need this for the tacho connection (white/grey stripe wire in loom). Other than that its just a case of making it fit. Post 1989 alternators with the 2 pin plug on the regulator can be used too, just loop the +12V sensor wire from the plug to the alternator output terminal. This is a common trick to use VN Commodore alternators on earlier Holdens.

ah ok thanks, heard that there was problems with noise from alternators and the ECU's.....

Dunno, OEM Bosch alternators are fitted to anything that has a motor, you'd think they had sorted it. Like, they have little suppressor caps fitted to their output terminals. Anyway, what electronics on a 300TDi are you concerned with? The radio????? central locking? Last I heard D1 diesels didn't have an ECU.

ok was just a story i heard but i thought better to check.

Chris it is very hard to find a configuration that fits a 300Tdi, the alternator legs are in an unusual spacing and shape. Best to just refit the right one I have found, as the belt will be right length etc etc. 200Tdi you can easily fit a Ford Bosch one, or a Mitsubishi unit as they are completely different to the 300Tdi, single groove V belt for a start.

ah ok after quote for 750 for new alternator i don't have that sort of funds available for it.

G'day Chris,

Why not buy online form the U.K?
I got a replacement for <$200 to my door, not sure about the longevity but it has been working fine now for 9 months.
Just a thought

Cheers

Rovacraft at Silverwater in Sydney have the correct 105 amp alternator for $305, plug and play, I priced one from the UK (Paddocks) , alt was $185, postage was $150, buy it here mate, Regards Frank.
