Hi Larry:
Thank you for the prompt and detailed post. I too am a KISS beliver. Went so far as ripping out the preasure water system on my boat. The pump was agravatingly noisy plus was able to deep 6 yards of 1/2 hose and an unbelivable number of hose clamps. For your post. I need to print it, read word-for -word, and draw afew pictures to get my non-electical mind wraped around your advice. I do have one follow up question. You mention my A-both-B switch. I have three switches on the BS panel. A On-Off house, On-Off start, and the On-Off parallel swithc that combines the start and house bank. I dont have the old style single swithch that has the 1-2-Both setting. When you say A-B-Both are yhou refering to three seperate switches or the old single switch with the three setings? I guess if I was smart enough I would be able to tell from your response, but........ if I was smart I would not have a boat! Bob |

@h3g2000cwc.googlegroups.com: A On-Off house, On-Off start, and the On-Off parallel swithc that combines the start and house bank. I dont have the old style single swithch that has the 1-2-Both setting. Wow, I like that KISS. You don't need to do anything! Unless the house battery is dead, turn 'em all on and crank the engine. Your alternator is ALREADY connectable to everything at once! The Parallel switch does what my ON-OFF switch does, already! If you kill the house battery, Turn just Starting on, first, then crank the engine. Once the engine is running, throw the other switches to ON and the charging goes to all the batteries at once...UNLESS SOMEONE WIRED THE ALTERNATOR OUTPUT JUST TO THE HOUSE BATTERIES! Trace that, please. NEVER, NEVER turn off BOTH the house and starting batteries at the same time, which unloads the alternator so its output voltage will eat whatever is still connected WHEN THE ENGINE IS RUNNING, or when your AC dock charger is running. Trace the big wire from the alternator and see where it goes. I bet it hooks directly to the starting battery, which makes my never, never comment above a moot point as one battery is ALWAYS hooked to the starting battery. That's where I would wire the alternator output...directly to the starting battery so it has no chance of running to an open circuit with your electronic stuff on it to be destroyed. The alternator output should be wired through a suitable fuse (alternator rating plus about 25% = fuse amps rating). This is in case the alternator diode rectifiers short out. I'm a fuse freak when I have to swim with the sharks because of an electrical fire. With all the switches ON, all the batteries, house and starting, are hooked in parallel to the alternator which will charge them....no wiring is necessary. Just make SURE noone switches both house and starting switches to OFF while the engine is running, just to be safe as we can't really see how it's wired up here on usenet...ok? That you'll have to trace for yourself. Larry -- VIRUS ALERT! VISTA has been released! NOONE will be spared! |
