Falcon or Commo, depending on how the alernator is mounted. They are the same alternator with a slightly different housing, you want EF-ish falcon or VP-ish commo, $40 from pick-a-part. It's a bosch 85A unit you want; some look the same but are 70A.

I just can't recall whether the TB42 has a two-feet kind of mounting (like ford) or the single big foot type of mounting (like commodore), and it's a bit cold outside so I don't want to go check

Here's my alternator upgrade it takes minimum mods. The bottom legs were wider so made up some spacers to suit the gap, but the top mount fit straight to the factory set up the wiring plug was spliced to suit the new set up but in worst case i can mount the original back on. It's been nearly 5 years since it was done but really wasnt much work. (I was working with an auto electrician mob at the time though) Awesome amount of power. I am able to idle around with 6 spotties and highbeam etc on while still charging at full volts Do a check on here as it's been on here before! hope it helps a bit!

Be aware that there is several mounting differences on them. The company I worked for supplied the Tarong mine gear that's how i got mine I had new bearings and brushes done once i found the correct mounting to suit. not sure if the serial/model number will help, it's too long ago and dont do auto electrics anymore. Also the pulley is a "made to fit" that was lying around the workshop!

The reg is internal on the tb42 standard ones (hitachi I think). Best bet is to take to auto electrician to "run it up" on a bench that way they can tell what's wrong and you can go from there. should cost bugga all and then you know for sure what to do, then spend some $$$. If there is nothing wrong with the alternator the fusable link may have blown. Not sure which one it is, but they are the ones near the positive terminal from memory there is a green orange and brown one. Sorry can't be of more help.

ok guys just an update on whats going on. i went back to the guy i got the reco alt from swapped it for another one and again same thing.

the alt doesnt work when u start the car it only kicks in when i rev it to about 2000rpm then its fine.

im not sure of the problem but iv done the bosch conversion 85amps.

any thoughts on this guys?

oh and the batt light in the cluster isnt turning on when u turn the key.
