Here are the instructions for the new regulator if that helps Regulator 35A installation PI4A026N Issue 2.pdf

It just depends on which regulator you have, the old ones go the the main bus, the new ones go direct to battery. Mike

The easiest way to achieve this is to use a single core shielded wire, connect the shield to ground at the engine and the wire to the mag. Then switch these two to ground the mag. When engine is running the shield is grounded.

Thanks Glen Yes, that is the servo in use. I'll get some Ferrites and give that a try. Appreciate the thorough reply, especially considering the number of replies you give across the forum for such matters! regards Mike

Thanks Glen The system is MGL and utilises CaBus for the control of the Servo. Unfortunately, there are a number of other CanBus terminations within the ground plane area as well, so the shielding lengths you mention are problematic. That was the main reason I was wondering if a metal shield would contain the lobing/Near Field of the signal and minimise the effect on the CanBus. (Probably not even remotely the correct terminology!) Would a solid ground plane be an option to minimise the effect of the Near Field RF. Mike

i all I have a jabiru with 2 axis A/P that works a treat, until I broadcast on my second comm. The antenna for this comm utilises crossed copper tape on the floor of the fuselage which continues around the Pitch Servo. The servo is effectively inside the ground plane, but not electrically connected to it. When I transmit on this antenna for longer than a couple of seconds the pitch servo occasionally fails and requires a reboot of the A/P. (Seems to happen most when on 123.45) Would the addition of an aluminium sheet or aluminium flyscreen over the copper tape shield the servo from the RF that is causing the failure? And would that sheet need to be electrically isolated from the copper tape? Thanks in advance Mike

Might be worth checking, I swapped the gauge out and was getting really good leak Down numbers, but when tested against another, and checked the orifice, it was always going to give 80/78's😀

I purchased this exact kit, total POS. (Not from there, and not that price though) The orifice size looks like it was blown out with Oxy! Been meaning to fix it but haven't bothered yet. (Using a loaner instead) Mike

No, only in unfortunately.

Sratux is a good option for the MGL iEfis, talks to it via RS232 and gives audio warnings based on height and distance you set. Total cost of about $120. (possibly a little more post COVID, I haven't checked recently) Mike

Thanks Nev, looked at this option a while ago but wasn't happy with the ratings compared to the likely surge current when jump starting from a Lithium jump pack. Just a quick edit - I hadn't considered using a starter that is only energised at time of use (by the start pack), was looking at continuous duty, your suggestion will work fine. Ill be giving it a go. Mike

What relay do you use to supply the jump start connector that will survive the starting current required for jump starting a dead battery?

Great idea, been wanting this for ages when outside vnc areas.

Try these, of the Jabiru website. https://jabiru.net.au/wp-content/uploads/2022/08/JPM3L01-5.pdf https://jabiru.net.au/wp-content/uploads/2019/08/JPM0001-6.pdf

Thanks onetrack, I'll try UK, but it's the Australian end that is the problem as I understand it. Worth a try though. Mike
