Yachting and Boating World forums: 12v Charger issues 14.4v at Charger and 10.83 at Batt'

I just can't believe this, 10 days ago the generator threw a power spike. The Sterling 50 Amp 12 v Charger dipped and then ran back up to 14.2 volts. However the Charge controller (Cedrc) is now reporting 14.4v and 0 Amps.
I talk to Sterling Tech Support who ask me to check the voltage at the charger and at the batts, both were at 14.2 so Sterling tell me that the Charger is running fne and there is probably a spot of corrosion on the PCB of the charger that is affecting the Amp readout.

4 Days ago and we seem to be consuming a vast quantity of Amps and volts the batts are down to 12.2 and falling, despite running the Genset for three hours.
I check the volts at the charger 14.4 and again at the batts 12.2, how can this be? There must be a break in the circuit somewhere. Where?

Last night with the batts down to 10.6v I tried passing some volts across the Big Charger fuse (60A 32v Fuse) I push 12.8v in at one end and I get 10.83v out at the other. Problem found and problem solved by installing spare fuse.
Question, what can cause this? What could cause the reduction of volts across the fuse?
Is it about to fail? (increased impedence)
Could there be a small short inside it?
The fuse was stone cold.

Als where can buy a replace ment fuse, this is a big bugger!?

Many thanks
