I've been following this discussion with great interes= t, as the new owner of a L IV (N84PL/serial #84).

Does the IV = use the same system and is it thus subject to the same failure?

Thanks for the detailed histo= ry. You=92re the second person to mention putting diode suppression across the motor terminals. I=92ve been following the LML and LNN since 2000 but must have missed that somehow. There have also been several good suggestions for bett= er or different relays. Since this is an existing installation, my plan is to = add the bridge rectifier mentioned in the attached article. That should accompl= ish the same goal of extending relay life and preventing future failures.

I=92ll take a closer look at = the relays when I go back to Ohio to retrieve my plane.

I'm surprised to learn of this failure and feel badly because I'm t= he guy who recommended the Bosch relays back in the nineties.
=85Do you int= end to take the relay apart to verify that the contacts are, in fact, welded? Bosc= h might be interested as well, but I certainly wouldn't mention that you&= #39;re using their relays in an airplane.
