Alternator amps at idle
« on: March 15, 2015, 05:40:06 PM »
G'day,

I have an 1991 Defender FFR with a 24 volt alternator. I want to use it to recharge a battery bank that will power an air conditioner over night. I was wondering what amps I would get at idle? I might need to get a new alternator that I can just turn over in the morning rather than do some laps.

I'm not sure of the 24v ones on perentie's, but most alternators won't charge properly until around 1500 rpm. You can throw on an ammeter and do a quick test. Might be easiest.
