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 :-) |

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! |

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, |

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. |

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. |
