FT9.9 battery charging and 220VAC battery charging

[abuonocoreca]

My outboard is an FT9.9 AMHL (1999), fitted with an original
6G9-10 SH652A-12 voltage regulator.


The original fuse is 20A.

The questions are:
1) which is the maximum power it can deliver (how many Amps ?) to charge the battery ?

2) from the service manual, the battery charger should be directly connected (via the 20A fuse) to the battery; I'm installing also a 220VAC external battery charger, and it's schematic also recommend to directly connect the 14VDC regulated output directly to the battery.
Then the two DC outputs from the outboard and from the AC charger would be directly connected in parallel, will this be a problem ? will I need switches to connect either one or the other of the DC outputs ?

3) if I need to use a magneto-hydraulic circuit breaker on the DC connection outboard to battery, which would be the right Amps ?

Many thanks in advance

Don't have any information on that model but the T9.9ELHX, 1999 fourstroke USA model has a 13 amp alternator and only has one 12v dc output lead to battery. Not sure what charger you are installing but most external battery chargers are connected directly to battery.
