EXP2BUS Quandry
The newly purchased EXP is mounted on my 9A panel as I continue to wire circuits.
Upon reading the wiring instructions, and noting that I am using an external master solenoid, the directions said to remove the onboard solenoid (relay) and install the "manufacturer supplied" jumper.
Well, I called the company. The tech was at lunch and would call me back.
That was last week and many unanswered telephone calls and emails from me and the vendor to the supplier.
At this point, I am at a halt.
Can anyone out there provide info on the jumper, where I can get one or what contacts I can jump solder.
The manufacturer supplier is unavailable for some reason.
Thanks to anyone for some clues.

This response is going to be utterly useless, so I apoligize for that in advance.....but do yourself a huge favor and just put in normal switches and fuses and/or CB's. In the end it'll be cheaper, lot's and lot's better, and you'll save yourself a lot of grief (I can guarantee you this won't be your last challenge with this thing). You'll notice we don't sell/service/install those (we do remove them though)....there's a reason for that!
Sorry I didn't help you out with your specific question....but I'm just trying to save you some more heartburn.
Cheers,
Stein

2nd Stein's advise.
I Have the EXP2 Bus and will at some point redo my panel as recommended above. Mine is functional, but has required a lot of effort to fully utilize. I ended up with remote swiches, and added extra busses for accessories anyway. The extra connections added to the complexity of my installation. I don't see any advantage over standard electrical plans. Read the AeroElectric connection.

It only took me about 30 seconds to bring up complete instructions on my droid based phone including complete instruction and a diagram on page 10 of how and where to wire the jumper. Search EXP BUS and find the Anywheremap related website. Mine has worked flawlessly for 220 hours in my day/ night VFR RV8. I consider it an inexpensive and simple time saver.

Got over 2000 hours on one.
Added (or was it removed???) the piece of wire that is a jumper for the external contactor.
It was documented back in 2002 when I did it.
Even though I agree with Stein that you are probably better off with the flexibility you get with fuse blocks (my second project has Z-14 from AeroElectric Connection), this device **CAN** be quite useful if properly applied.
It works fine for a simple installation. Of course mine grew a bit more complex over time and I in fact did add fuse blocks, but the original stuff I connected as well as the "Backup Battery Bus" implementation with it still works great.

My RV-6 was built with one and while it's worked mostly just fine for 400 hours, I don't especially like it. I too plan to replace it someday with conventional circuit breakers, which I'll feel more comfortable with.

EXP2BUS
Thank you all for your replies. I wonder how many units are out there that function correctly. I've looked at posts since 2006, and it seems there have always been issues from, at least, those respondents.
I did go to the Control Vision Support site, but still have no answer about the relay jumper. The company doesn't respond at all, so where to get this jumper? Or, what terminals to solder?
I would never use this product again, but $460....and then more for switches and CB's.
My recommendation is that Van's or Aircraft Spruce should not sell these products if tech support is not available.
If anyone could advise me about the relay jumper, thanks.

Bluebear ....
First to repeat a couple of points.
1. If you use the fuse block approach you WILL have more flexibility down the road.
2. If you use the EXpBus, you WILL have to study their docs (which could stand some improvement) to get the real value out of it.
3. You will find more support available for the fuse block approach because so many of us exist that use it.
Now, if you contact me offline, I will work with you to sort out the jumper **IF** you have already chosen to go the ExpBus route. (Or if you have a plane with one already and just want the contactor to handle heavier loads and add more stuff (as I did).

I got one from them in 2012 it was $5.00. Unfortunately I did nit take a picture. It is very easy to install. I'll be by the aircraft later I'll try to take picture..
