Re: Buckeye Tailgater.... IN PROGRESS

The diagram is too small to read, and when I copy it to my computer and blow it up, the resolution is too grainy to make out. A couple of things I do see:

1. How are you charging your "aux" battery bank? There is no connection to the alternator, except through the connector of the device at the top left. I can't make that out. If it allows current from the alternator to charge the aux batteries, then it will also allow current from the starting batteries to charge the "aux" batteries when the engine is not running, unless there is a voltage-sensing disconnect similar to a Charge Guard. If you join the two banks together at this device, you have in effect one bigger bank, and can expect to run the starting batteries down with the aux batteries.

An isolator would be a good addition. The alternator output goes to the middle, and each end connects to one bank. The rectifiers inside an isolator charge the weaker battery bank until the banks are within less than a volt of each other, and then charge both together.

2. I don't know off the top of my head whether #8 wire to the device and then to the "aux" bank has 120-amp ampacity, but unless the device between the battery banks employs a current limiter, pushing 120-amps of charging current through "30-amp fast-blow fuses" is going to cause a lot of blown fuses. If the "aux" batteries are discharged more than the starting batteries, all the current will seek the weaker batteries.

If I understand you correctly, you are using two Red Tops to start the bus, and you want two Yellow Tops to power the rest? As much as I like the idea of Optima batteries, I checked out some Yellow Tops and found that for over double the price of Trojan 6V batteries you only get 55 amp/hours of capacity per Yellow Top. The Trojan batteries have 225 amp/hours and while you need to have at least one pair to get 12V, the pair will provide more than double the capacity of a pair of Yellow Tops. Something to consider. I had to explain it to my brother a few days ago because he thinks that Optima's are the best thing ever because you can store them upside down and inside out or whatever. I would rather have capacity than gimmicks.

When RU joins the Big 10 I am hunting you guys down when we go out to the shoe.

Re: Buckeye Tailgater.... IN PROGRESS

Nah, there are two tailgate lots at RU that allow RV's with no problems. My buddies and I donated enough money to most likely get into one of them. Our plan for a few Saturdays is to park in the lot on Friday night, go out and party at RU and then sleep in the bus and wakeup for the tailgate the next day. I can't wait haha.

Re: Buckeye Tailgater.... IN PROGRESS

OK, the Magnum Smart Battery Combiner joins the batteries when the voltage on the primary batteries rises due to the presence of charging voltage. Good deal. Please note that the device has a 25-amp rating, and the drawings in the manual show the charging source as a Magnum inverter-charger. You cannot just substitute a 120-amp alternator for the lower output of the inverter-charger.

PLEASE, PLEASE, PLEASE connect the unit in the configuration where it is switching a heavy-duty solenoid, as shown in figure 2-6 on page 8 of the unit's manual. Otherwise, you will be repeatedly blowing the 30-amp fuses, or burning out the Smart Combiner if they don't blow. Thank you.

Re: Buckeye Tailgater.... IN PROGRESS

Much better, but look at the manual drawing again. In the solenoid application, the Magnum serves as a sensor and solenoid controller. The MAIN POS terminal serves as the charging voltage sense input, so the added REMOTE SENSE wire is not needed.

The purpose of REMOTE SENSE in the 25-amp configuration is to prevent the controller from acting based on lowered voltage at the MAIN POS input due to high charging current through the resistance of the wire and terminals feeding it. With the charging current going through the solenoid, this voltage drop is not a factor. The REMOTE SENSE is optional (though recommended) in the standard installation, figure 2-5 doesn't show it installed.

Re: Buckeye Tailgater.... IN PROGRESS

How did the interior pads being painted red turn out for you and what did you use? We're using our stripped bus seats for cushions on our couch and originally I was thinking of stitching red felt on them but they'd probably rip. I thought about painting them but then figured it might feel weird to the touch and the paint could crack from people sitting on them.

Re: Buckeye Tailgater.... IN PROGRESS

How did the carpet go for you in your bus? Did it get messy? We were thinking of buying the cheap astro turf carpet instead of laminate flooring.
