[C320-list] Starter Battery and Fuel Tank Question and Parts3Engines.com Warning

[sail-ability at sympatico.ca]

You have done well to get 8/9 years from that bty. It sounds like your system is wired wrong. I have starter bty on position #2 house#1 and both on both. They charge independently and both on both. 
As far as your fuel tank, you can suck out the fuel using an oil extractor. Diesel fuel will not harm it but gasoline will. I did this and took the tank to a rad repair facility for an inspection and cleaning. It’s difficult but the tank comes out through the hatch in the aft cabin once you remove the door and frame. Some of the older tanks were leaking so I wanted the insurance. Turned out the tank was fine but it was dirty.

Do most people with a separate starter battery have a car battery with similar CCA? My starter battery is wired to #2 on my selector switch. However, it receives a charge even when the switch is in the 1 position. Is it supposed to do this? For some reason, I thought I would need to have the switch set to both for both to charge. This issue came to my attention because my alternator is not working and I went on the hook overnight. I drained my house bank batteries and switched to #2, whereupon I discovered 1V in my starter battery. It has probably been dead for a while.

My plan is to suction all of the diesel out of the tank, put some acetone in the tank and slosh it around. Suction any residual acetone and vacuum the tank. Will this work? Going forward I will add a biocide to my diesel and make sure that I keep reasonably fresh fuel in the tank.

My $135 alternator will cost me $200 if I use Fedex or UPS to send it back. I plan to stop by USPS tomorrow and see their rates.
