Alternator Questions / Full floating ground alternator
« on: September 20, 2010, 02:36:41 PM »
I have an RV with a "start battery" and 4each "house batteries".  The house batteries have an Heart 2500 inverter/charger(110VAC).  Right now all batteries are charged from one self-exciting alternator, via a combiner relay.  I am looking to add another alternator to charge the house batteries.  What I need is a full floating ground alternator so I can put the negative terminal on the top side of the shunt and the positive terminal to the batteries.  By doing this the Amp-Hr meter will clock down as the alternator amps flow through the shunt.  Do you have such an 100 - 140 Amp alternator?

Alternator Questions / Over Charge circuit
« on: October 21, 2009, 05:09:34 PM »
Is there some way to fool the alternator into overcharging a battery for a while.  For example, I deep cycle a battery bank every day using about 30-40% of the 400 AH (100%).  When charging the bank.  I would like to fool the 105 amp alternator regulator into charging at 50 Amp or more for 30 - 60 minutes (bulk mode) to get most of the charge back into the battery bank before it goes manually back into the "acceptance" mode.

I also have one 180 Watt solar panel and a wind generator hooked to the system but on certain days there is insufficient power added to the battery to maintain charge and I need to run the alternator to ensure recharge.

I have hear that there is a way to add a diode into the "sense" line to fool the alternator into thinking the battery is at a lower state of charge.  Can you also fool the "one wire" alternator set up as well?

Alternator Questions / Alternator Charging Issue: Delco used on sailboat
« on: October 21, 2009, 04:42:41 PM »
I have a sailboat with a Yanmar 30hp Diesel.  The problem is that quite often the Battery Monitor Panel shows that the alternator is not charging.  Some minutes later it mysteriously starts charging.  My normal RPM is 550 to about 1800 and I do not take it to 1800 until unit is well warm.  I am not sure what the pulley rations are but I would guess 3:1 but I can measure next time at the boat.  I also have a spare that has checked good.

The unit is wired such that the big red wire goes to the start battery, via a Combiner, and another smaller wire coming from a black flush oval terminal block is directly connected to the big red wire.  I do not know if it is the field or sense wire (or any one of the other ones under the oval terminal).  

How do I determine if this unit has a "one wire" regulator or the "standard" regulator?  What happens if the sense wire and BAT are tied together using a "standard" regulator?  What Happens when "one wire" regulator sense wire is tied to BAT?
