Hello all,
Got another one for you please.
Don't ask why but I have just discovered that my Yanmar 3JH25A diesel 3 cylinder (ex lifeboat engine) has a heating element in the air intake for cold weather starting. It draws 33 amps. As I am in Greece it is unlikely that it will ever really be used but we do have some cold spells (minus 2 degrees max) in the winter.
As I have already had the dash panel cut and drilled there is no aesthetic place for a push button switch to control it.
As it needs to run (according to Yanmar) for 60 seconds on start up, I thought a timer/relay would be a good idea. This is ok but the relay I found is only rated at 10 amps, so a secondary 40 amps ordinary relay will be wired after it. The 10 amps timer relay can be set to run for 60 secs from on.
Question is, do you think wiring the control of this through the ignition/starter switch would work? Ignition - on nothing, and turn to start to initiate the heater?
I could put a simple on/off switch hidden away somewhere after the starter switch to make it summer/off - winter/on because it really wont be needed for 10 months of the year.
I'm not sure how quickly the heating element warms up and so I could be cranking for a few seconds before warm air is sucked in?
Any ideas please.
