I'm a huge fan of my VPx. I think it's pure magic.
On the new product my questions would be, how does this new box work with rear batteries (RV8) and how does it replace the ground block?

very nice, marc!
the inherent firewall passthrough is a brilliant idea, agree somewhat though that it may only work with certain setups/aircraft.
how about making two versions with the stud either fore or aft?
if a single version is a must, i'd rather go for the stud firewall forward
also, an ammeter / charging / decharging sensor inherent would be great!
other than that, design, approach, everything looks vertical power quality :-)

In that case you do have to leave the master solenoid in the back per Van's plans. The master switch would be wired to both the solenoid in the back and the PPS in the front. The PPS would be mounted on the firewall where the starter solenoid is on the -10 today.
At least I think so, we haven't tried it yet. Can anyone with a -10 see how this might fit there?

It wouldn't quite fit there (there's some other stuff, like the sender headers on the hot side and the brake line bracket on the cold side) but it could be located nearby. More to the point, for a -10 I'd also want the battery lug on the back side so I don't have to make another exposed firewall penetration. Or, remote the starter instead of the master; there's plenty of room in the tail for your box.

I'm not sure if the VP-X already handles this but my A/C is separate from the VP-200 system due to the power load (though it could certainly handle the solenoids for the AC).
Also, will it handle dual batteries and/or alternators? In the diagram it looks like you have two alternators feeding into a single input but how would that work?
|
Patrick - thanks for the feedback!
It will not handle a true dual independent bus system (See Aero Electric Z-14 diagram), but if you have a second battery used to backup avionics that can be wired in separately.
Detailed wiring diagrams coming soon!

The batt and the starter posts are backward to mount FWF in a 10, at least in the same location as the starter solenoid.
Starter solonoid is above the oil cooler here, batt feed wire is the one with the 180* turn.
A rear feed for the batt would work well for any setup with the batt in the back.
What about those of us running dual alt/dual batt in a parallel setup?? I could see two of your boxes working with only the addition of a cross feed to the essential buss------or a single box with dual inputs for batt and alt.

Well done!
Hello Marc
Well done! I would buy it on the spot.
Same comments as Bernie.
But, make two versions, so that it fit for each style nice and is not a combined solution.
Regards,

Rear battery - wiring diagrams coming, but it will work.
We're currently proposing that the system comes with a 'farm of tabs' for the ground block. The hole spacing matches the mounting holes on the back of the PPS so you can mount it on the inside of the firewall, or you can mount it anywhere you like really.
The large hole is so you can also mount it to the big ground cable coming from the battery. We're planning to offer the ground block separately as well if you need more than one.
Thoughts?

If I were building again ....
I would definitely consider this option. This certainly would have made wiring FWF easier the first time - when I had to figure out how to do it and what components to use (I did not use Van's components).
A couple of questions:
1. I use a 3 position switch for the Master/Alternator field: Off/ Master only/ Master + Alternator. Can this device turn on the Master without turning on the Alternator also?
2. I have an Emergency E-Buss Switch which applies power to the E-Buss with the Master Off (i.e. Master Contactor Off). I presume if I wanted have the same capability the PPS, I would do it the same way I do today (direct to the battery). Right?
3. I use toggle switches for my ignition and a separate push botton for the starter. Would the pin outs of the "starter switch" on the PPS support this configuration?
Good luck with this product. I looks great.

1. & 3.
Rick, the pinouts are designed to exactly mimic the way you wire these things today. So any switch configuration you have today or are planning to use will work with this.
2. Yes, go right to the battery lug. The longer lugs here are exactly for that purpose.

Will it support ammeter outputs for the EFIS for each battery and alternator?
I could put this in today. I'm right there.
