RE: ACK -E04 ELT antenna install on RV 8A
…bifft
Did mine at the empennage, but not under the fairing. Tilted forward just ahead of the vertical stab. I did need to make a cutout in the back of the canopy skirt for when the canopy is fully open.

RE: Denso Alternator Regulator 126000-0600 Testing

Noodling on this -- forgive me if magic smoke comes out
See picture:
You will have to rig up something to spin the alternator -- the ND architecture uses the stator input on the regulator (the screw lug on the left side) to determine if it's spinning and in need of regulation. Maybe you can synthesize this by putting a nominal starting DC voltage (12v) on the stator input.
You will also need a load between the B+ lug and the F lug - use the brushes/rotor assembly here. Use jumpers to connect between B+ & slip ring 1, slip ring 2 & Voltmeter +, Voltmeter - to F lug. If you don't want to use the rotor, swap in a 5 Ohm, 100 Watt resistor to simulate the rotor.
Connect the ground lug (bottom) to ground on the supply. Connect the IG plug wire to your + DC supply, this will serve as the activation signal. Connect + DC to B+ lug on regulator (the one with the arm sticking out from the connector). This will simulate the alternator's voltage output.
Start with 12Vdc on the supply and slowly increase the voltage. What does the voltmeter show? As you increase the supply voltage you should see the voltmeter value decrease -- play with this a bit around 14 - 14.5 V. If there is OV protection (non Crowbar), you should see the voltmeter suddenly drop to 0V as you approach ~16.5V on the supply.
Make sense?

ACK -E04 ELT antenna install on RV 8A
Have any RV-8A owner installed an ACK E-04 ELT? I'm having a problem finding a satisfactory place to mount the antennae. The sliding canopy eliminates the aft fuselage, under the the canopy just behind the rear seat perhaps? Would appreciate any suggestions. Thanks , Jim

Pitot adapter question
I'm finishing up the last few things in my wings and went to start mocking up the dynon pitot tube with the lines to see how to route them. I tried threading on the plastic line compression fitting to the flared adapter but it only goes on a few turns before becoming quite difficult. I did not...

Denso Alternator Regulator 126000-0600 Testing
Supposedly this Denso 126000-0600 regulator has over voltage protection. If so, perhaps one could start there and look for the 55-60A alternators that it fits, and see if one is airworthy? If you have one of these in hand, how would you test it and it's over voltage protection without having it...
