TD42 Alternator

[Rossco]

Hi guys, just put new 90A alternator in last night. Seems to be working awsome, hopefully not to well, don't want to blow up any batteries. Idle battery is around 13ish V running is at around 14.8. Does this seem to be pretty normal or to high. His just used to the old one i guess that didn't get much above 12 on the factory gauge or fluctuate with revs but think it was getting dam fubar for a while.

Few revs.

I'm of the understanding a healthy 12V battery is charged up to around 14V so I wouldn't be worried, I'd be happy!

Sounds about perfect to me mate.

14.4v was lead to believe all ok?

My dash gauge reads inaccurate too. It shows 16V where a multimeter will show around 14.4V

Ah sweet guys thanks. Thought so, just bit old paranoid! ! Guess it's a case of getting used to something crappy and stuffed. Think that old one was way under par for ages. Pretty sure this is why i wasn't getting more than a day of just sitting to keep the fridge running before the battery dropping and wouldn't be surprised if there's nothing wrong with the solenoid either.

Another quick Q, should i be worried blowing the main fuesable link with a 90A under winching or should it be all good?

What size is the main fusible link again? I popped it a few times with the 120A alternator. I have run a 16mm welding flex cable from the alternator to the battery through a 120A circuit breaker.
