    While out the other night, the car dash lit up like an early christmas tree with a lot of malfunctions... Consumers shut down, Brake defective, ABS, ESP, SBC.... etc etc.

    The rear battery is a new install (less than 1 week) and the small battery in the engine bay is relatively new, when I had the SBC pump replaced a few months back.

    I tried taking the voltage reg. from the back of the alternator, rather than complete removal of the alternator, but, it seems one of the nuts has rounded off and I cannot grip it sufficiently to undo, and space is very tight. So complete removal has become the only option.

    However, trying to remove the darn alternator seems a challenge into itself, from abover too. I have removed the air filter housing and two pipes for the water pump, but i am struggling to get the alternator out of the tight space. There is very little room between the water pump, a electrical box? and a metal offshoot used for a bolt to the alternator... so seems to get a little bit more room, the only option is to remove the fan.

    Does anyone have removal process to get the fan out, please?. Im sure its not difficult, but.. :)

    Thank you for the links.

    I had a go at the fan, and managed to get it out.

    The new alternator is in, and so far, looking good, with the rear battery sitting at 14.1v with the engine running :D
