Question about 'House' battery connection...
Hello all..... I am undertaking converting the original battery
configuration in my 84' PT 40 and I have some questions....... Original: 4- RV deep cycle 12V batteries mounted on a battery tray in the engine compartment, + lead connected to a power distribution 'stud' with 2 leads directly connected to the starter & 1 lead directly connected to the 'Jump Start post' at the rear of the compartment on a frame rail which then is connected to a couple of relays that are connected to the key switch and the selector that allows for the engine to be started from the 'rear' or 'front' ignition switch. New: 2- 12V starting batteries in the engine compartment. 2- 4D deepcycle batteries in a 'new' converted stowage area just in front of the 'rear' wheel axel. Issue: I want to seperate the 'Start' batteries & the new 'house' batteries.... I have an isolator to accomplish this.... however I am having difficulty determining where the power source for the current 'house 12V' is coming from...... it seems that when I look at the starter.. there is 5 heavy guage wires connected to it... 2 of which come from the + battery connection post and 2 of which go into the compartment that houses the existing isolator, DC-AC redi line generator along with 3 relays that appear to all be configured to switch between combinations of power UP for the redi line, the generator battary and some other features... but none of the connections seem to be the connection to the existing 'house DC' supply... In order to properly configure the new battery configuration I have to isolate the dc supply for the starter & the ignition switch and seperate the existing 'house DC' so that I can supply each one with it's own battery bank.. and place the isolator between the 2 so that both battery banks are recievng a charge from the AC charger and the alternator...... Does anybody hqave an idea as to where the existing 'house DC' connection is coming from??? is it one of the cables attached to the starter??? or do I need to look elsewhere??? Thank You Brian 'The Green Hornet' |

Question about 'House' battery connection...
Hi Brian,
I'm not there to do testing, etc., and we don't know who did what mods. over the years...but my guess is the house 12V passes from the batteries(starter) through the inverter. On Tue, Aug 19, 2008 at 5:26 PM, t3brian <"brianp@t3networks.net"> wrote:

Question about 'House' battery connection...
Hi Curt... how are you???
OK... well... I do not think that I even have an inverter.... Not anywhere that I find anyway....... the only items in the area in the engine compartment near the batteries are the redi-line generator for the AC to the curtins... and a charger.... then some relays and an isolator that is connected to the gen. battery and the original bank of start-house batteries..... so I guess what I need to do is remove all of the wires from the starter and begin to isolate them to see if that is where the existing 'house DC' connection is being originated....... Thank You..... I will keep looking tomorrow..... If I can't find it right away..... do you think that it would be a problem if a ran the 2 new sets of battery banks in parrallel for a week long trip that we have planned at the end of this week???? I have 2- group 31 starting batts & 2- 4D deep cycle batts. --- In WanderlodgeForum@yahoogroups.com, "Curt Sprenger" > > Hi Brian, > > I'm not there to do testing, etc., and we don't know who did what mods. over > the years...but my guess is the house 12V passes from the batteries (starter) > through the inverter. > > On Tue, Aug 19, 2008 at 5:26 PM, t3brian > > > Hello all.....

Question about 'House' battery connection...
rediline is a AC generator using dc power from the batterybank to
turn a dc motor that rotates a small genhead???? the rediline is often replaced with a more efficient inverter. I have a big bank of batteries but the math proves that twice the bank size takes twice as long to charge with the genset. a charging schedule where the genset runs during high ac demand times may prove helpful also. You can hook a second bank up to any big wire dc terminal but you need a way to charge the extra demand too. Isolating the start bank from the house bank will not increase your house supply it will only ensure you have juice to start the Detroit. you may want to only isolate the two banks on the last day of your week long camp out.

Question about 'House' battery connection...
OK.....
Well after listening to and understanding many thoughts about the original design and layout of the coach system ... I think that for now I am just going to hook up the new sets of batteries in parrallel and consider it done. That wa I am relying upon the generator & it's start battery as the 'backup' plan to start the coach....
