I’m new to the forum as a contributor but have been mining it for inspiration for my boats for years.
I just had a very weird thing discovered about the charging
on my boat
and I just wondered if this was normal.
Na Mara is a Regina 43 with a true pilot house with interior
and fully doubled engine
controls. About a week ago it was a bit narly and we were headed right into it on the engine
so I started the engine at the internal helm
and watched the world go by in true slippers sailing fashion with the autopilot
on until the engine died three hours later. That never happens!!!! After the shock wore off we sailed back into harbour and got the pros out.
The problem was identified as being that the alternator
was failing to charge the batteries
. It turns out that the fuel pump
is run off the starter battery
and it takes a bout 3 hours of running to run down the starter battery
enough for the pump
to fail and the engine to die. The pros checked everything and basically came to the conclusion that it must be the alternator
. A week later we got hold of a new one and fitted it. Still no charging! The very embarrassed pro then spends the next hour in deep head
scratching until he finally strikes upon the idea of starting the engine at the external helm. Lo we have charging!
Upon further inspection
it turns out that 25 years ago the boat
was delivered with two engine panels
from which you can start and monitor
the engine, only one of which activates the alternator for charging
The pro and I have never heard the like before.
1. Why fit an engine panel that, if you use it, runs down your starter battery?
2. Has anybody else had this sort of issue before?
3 Why has this fault not been corrected in the boat’s 25 year history
? Others must have discovered it in a similar fashion to us.
