I have my voltage regulator set at 26.84 volts, is that good? was at 28.85.
There is already a wire ran from the bus bat. to thehouse bat with a switch in line I hooked it to pos on house bat and from 12 volt side of bus bat.
should it charge that way or do I need to ground house battery to the chassy? |

Nooooooooo. I have a wire coming off of the second battery on the positive side. at that post there is only 13.6 volts if I remember right, mabee 14.6. so I'm trying to charge from that battery only not both bus batteries. |

Regulated 28.5v is normal for charging on the mc9...
Uhmmm... I don't think you're going to charge any 12v battery
using a tap between the two 12v in series that are being charged
as a single 24v battery. As soon as the regulator sees it's 24v
(28.5?) it'll stop charging and it don't give a rat's butt if one of
the batteries is only 11.5v.

What you have created is a series/parallel bank of batteries. Save some more money because you are going to need it for new batteries real soon; this arrangement is going to kill your batteries in a short time. Yes, the "dangling" 12v house batt out there needs to be grounded to provide a path for current flow, unless u just want to use your 12v loads to do that for u. |

You can not pull 12 volts off the center of the 24 volt batt. with out ruining one or both of your starting batts.
You need a battery equliser to draw 12 volts from the 24 volt batts to do it that way.
Go to the Vanner web site all the info on this there.
My bus holds at 28 volts all the time checked at the batts.

One way to make it easy is to use a 24 volt house batts then the charging is easy off you start batts. It is a little harder to find low priced 24 volt inverters .
And if you have some of your bus lights 12 volt you should get a battey equalizer and run all your bus lights off 12 volt. You could also charge your 12 house batts using the equalizer but you would be only charging them with the size of the equalizer and it would be cheeper the buy a 24 volt inverter then equalizers that would be large enuff to to that.
I have a Vanner 65/100 so I have 100 amps of 12 volt for all my bus lights that I changed out to 12 volt . Now I can buy my bulbs at walmart for pennys not $12 each.

When I bought 24v flashers and marker bulbs for my ex-MC8, they were more than 10x the cost of a comparable 12v lamp.
Maybe you should buy all of your bulbs at that place, CR.
