Hi all. So i replaced my batteries and alternator a couple of weeks ago. 1.5 BMC, new 55 amp alternator and 3 95ah leisure batteries (the 105s are just too big for the battery box). All was good once fitted. Seeing 14.5v to the batteries (according to the solar controller). I have renewed exactly the same set-up I had for the last 5+ years as it has worked well.
Yesterday the fan belt was squealing. Fair enough. Loosed off the mountings, gave the alternator a good tug, tightened them up. checked the connectors. No squeal and the charge light gone out. Excellent. Job done.
But no its not. Now I am only seeing 13.6v. I have double checked everything, always had 14.5v plus - up until today - from this set-up. Fired it up again today. Still 13.6v
Why? The connections look good. The belt is definately not slipping now. Where have my volts gone?! Is it really likely my new alternator has gone duff already or should I be looking elsewhere?
Thanks for any ideas. Jak.
