There are three battery
combiners. a stock alternator
and a balmar 9500 210 amp. The balmar is supposed to charge the house battery
, the stock charges the starting battery. At 13 volts the two are combined, same thing happens with the port engine
. But the port batteries
are the "reserve" batteries or house bank 2. When house bank 1 which is now paralleled with the starboard starting battery reaches 13 volts, it is paralleled with the port reserve bank, which has already been paralleled with the port starting battery after the port engine
charges them up. Same deal stock alternator to the starting battery, balmar to the house. Now, each side has a balmar max charge mc512 voltage regulator attached to the balmar alternator.
o.k. so. now the fun part. The port engine doesn't work
at all. 5 of 6 deep cycle batteries have one completely dead cell. and neither starting battery will start the engine alone. So I have two starting batteries hooked up and the one deep cycle in house 1, just to make it as simple as possible. The alternator/s put out 30 amps to the one deep cycle IF the battery SWITCHES are manually turned to all. That is if I manually combine House 1 with Port 2, Starting Startboard with House 2 and Starting Port with House 2. So I think what is happening is the stock alternator is charging
the starboard starting battery and it has to be paralleled with house 2 which is then paralelled with House 1. So it's a round about way of charging
house 1. After 1 reaches 13, the combiners take over, but I still have to keep the starboard starter and house 2 together manually or else the amps never make it to house 1. And the battery combiners never combine any batteries except starting starboard and house 1, except once when i used a charger
on house 2.
So if you're still following this. I get all the correct readings on the balmar voltage regulator port side, but nothing at all starboard side, where i need it. So i switched out the harness, the regulator, and still nothing starboard. Finally I figured out, after frying both harnesses, that the voltage sensing red wire which is supposed to be on the balmer alternator output with a 10 amp fuse, kept blowing. So I'm thinking that what's happening is that because no amps are flowing to the house battery from the balmar alternator, the current
all goes through that little voltage sensing wire and blows it up. So I need to put the voltage sensor on the starting battery. wow i just figured that out by writing it all down. I'm still going to publish this, just in case someone out there has any idea what i'm talking about.
Now next problem: The reason I want the regulator to work is because it has an equalizing mode and I'm trying to desulfate the 5 bad batteries. I have connected the output of the balmar alternator to the field terminal, like it says in the manual, but I still can't get the batteries higher than 14 volts. So I'm thinking it's the stock alternator might have an internal regulator getting in my way. So I should try to full field it also???
