Thanks very much for the help. Looks like I have a way forward.

When I started my Velocity build, I installed embedded antennas in the wings with RG58 also embedded from the wing root to the antennas. Now I need to complete the rest of the coax runs to the radios ...

Are the typical ND IR alternators of the Internal Regulator A-Circuit type with the control input simply bonded to the B-lead? If so, then the mod I've performed with the non-conductive screw (in the ...

Hello All,
I got some non-conductive glass-filled nylon screws (m4 x 10) from McMaster Carr today to test my proposed alternator mod. Photos of my mod are attached below. The mod was extremely simp ...

So I just reviewed the Kitplanes article and it got me thinking of a potentially simpler solution. Please tell me if I'm crazy, but why not just replace the screw in the left brush mount with a non-co ...

Thanks Bob, you read my mind!

Bob,
Thanks for the explanation on the B-lead contactor and progressive field switch.

I like the direction you're going with the B-lead crowbar solution. Seems like it could make the OV event mu ...

One of the things I've always wondered about with Z-24 was the impact of the B-lead contactor opening when the field switch is opened. This appears to negate any positive influence of having a progre ...

Hi Bob, I've been doing some searching and found a couple of tutorials on modifying an alternator to external regulation and am considering whether to attempt the mod. While searching, I also found a ...

Thanks for the explanation, Bob! Looks like it's the metal can or alternator surgery. I'll do a little research on my alternator and the best surgery option.

Hi all,
I'm using an IR alternator as my primary source of electrons on my Velocity. I'd like to provide overvoltage protection to include a B-Lead disconnect relay. With a 34A continuous normal sy ...

My build is a Velocity which planned for night and IFR flights. Load analysis shows Z13/8 would work fine, just happened to have a 20 Amp alternator already hanging on the engine...

Bob,
I've resumed my build after a 10-year layoff and had installed the 13/8 architecture. Turns our the engine I bought to hand on the firewall already had a B&C 20 Amp alternator hanging on th ...

Bob,
Maybe it's in there, but if one has to power down the main bus due to smoke/fumes, is the Engine Bus then relegated to battery duration only? Is this an argument for having the aux alternator ...

Moving this to the correct thread. Anyone see any issues with Bob's new/proposed architecture for an IO-360 with one mag and one electronic ignition? Would folks recommend the ignition be on the Bat ...

Hello all, I’m wiring up my panel and connecting an SL30 nav/com to my MGL iEFIS. It appears my SL30 is not transmitting over the RS-232 serial line to the iEFIS, so I checked my wiring and it app ...
