I've a recent problem with my Dickenson Newport diesel
heater's fan. Every few hours it blows the breaker. I am wondering what is the source of the problem.
I have an aluminum
hulled sailboat. I bought the stove used and do not know how many hours it has been used, but it does look in good shape. The fan is 12V. The positive and negative sides of the circuits are fused and switched separately at the main 12V electrical
panel. The 12/2 wire run is about 8 feet to the heater. The boat needs a rebuild
inside and I've set-up temporary wiring
. The 12V positive is switched from a 12V tap with an on/off switch, then a 1/2 A fuse and then the wire run to the heater. The negative side of the circuit is run from a Vetus P12 breaker panel. The P12 has built in 10A breakers. This is the breaker that blows. There are quick disconnects for + and - circuits at the heater. There is no 120V AC circuitry on the boat.
