Never again will I take on such projects in the spring! I had all winter to do this work and it seems like it took forever!
Project 1; that grew into a major revamp; I had this Blue Seas ACR and this is what I wanted to do
Of course I realized I needed this to make the the whole project viable.
Well I started collecting things to do the complete install of the switch and relay, and started this thread; https://www.sailnet.com/forums/electr...being-anl.html
While being ANL I started thinking about warnings from Mainsail and the dangers of having an old ammeter on the engine panel. So I went for it! This thread covers that project!
"in for a penny..... I get the Leece Neville 90 amp alternator. that went quite easy and after the new pulley came we put that in in less then a half hour.
Not to be defeated by mechanical issues I saw that the engine coolant pump was leaking over the winter and decided to let that wait until the above projects were close to done. Well Today was the day that we did the pump! This is the thread on that!
Well it's all officially "done"
The coolant pump is quiet! the new Alt is quiet! The battery banks are truly isolated!
Here's how it all goes when boarding the boat.
Put shifter in neutral raise throttle to med speed (no tach) Press button for glow coils. 15- 30 now. used to take longer. (new wiring gotta love it) crank engine it comes to life!.
New Volt meter shows 12 volts for about 30 seconds and when the field coil in the new 90 amp alt comes to life the needle jumps to about 14.5 (it's not digital) I can actually hear the "load" when the Alt comes to life and starts charging.
As the engine warmed up I was ready to shut it down since I was sure the water heater would have a "bubble" in the heat exchanger. It did... burped the HW line at the water heater and tried again...added water... tried again.. burped one more time... Temp gauge drops to it's normal 150-160... The quiet is wonderful.. I mean one can still hear the diesel. Looking in on the charging relay .. the little LED is on combine, meaning the Alt is charging both banks.. and all this is happening while the ice box refrigeration is running for about 2-3 hrs.
When the engine is off the starting battery is not used and completely isolated from the house bank unless I put the new switch on "Combine" (I don't think I'll ever need to do that because the ACR will do it if necessary.
So... I'm ready to put the interior of the boat back in order and do some river sailing! Maybe even a few overnights at Tullytown cove.
