Re: Amperage values "float" during engine operatio Mostly this is caused by a loose/poor connection, make sure they are all good - don't ask me how I know ::) Jake J

From my perspective 2 foot extra would give a safe margin. Jake J

May be a good idea to check all the connections - I just recently found a 'bad' Dsub connector that, although the socket clicked in, a gentle pull on the wire allowed it to come out - just one of those things that happen rarely ::) Jake J

Good call David - I usually have to make 'adjustments' to the loom to compensate for the 'short' wiring. Dynon I'm very happy to pay for the extra length for the 6 cylinder (RV10) Egt/Cht wiring harness. To keep parts count down it would mean that the Jabby 3300 wires would also be longer, so...

David I usually mount them forward of the main spar nowadays - works well & the exhaust won't affect it. Jake J

Rob I had a similar problem recently (vers 5) - volts were always ok but amps up and down. Traced fault to one of the main battery leads not being secured properly ::), let us know if this fixes it. Jake J

I've found the same problem once - traced it to the pin in dsub connector not being seated home properly, hope this helps. Jakw J

I'll see the plane in a few days time - will report back

More info from owner/builder - Initially Ammeter was showing +5 to +13 Amps no load and +15 to +26 under load ( Nav & Strobe lts on) last 2 engine hours it is showing +13 to +25 no load & +15 to +26 under load.

We have a B&C 40 amp Alternator fitted to an IO-360 & D120.  Since first engine run the ammeter shows a fluctuating high (+5 up to +36) amps output however volts are always stable at 14.1- 14.2.  Turning on 'loads' exacerbates the reading - any thoughts on why this is happening ?  Shunt is in...

Re: Noise from headset after upgrading to version Ivor - FWIW, coincidently I've just had the 'noise' problem with my 8yr old PMA6000MS, the squelch circuit has problems so I'm upgrading to the 7000B 'slide in' replacement. This 'noise' was noticed right after the annual but had an...

Dirk, this is a long shot - why don't you run a new 4 core wire temporarily through the plane from the EDC to D10 ans see if this works ? Seems like a wiring issue to me too ;) Jake J

FYI - I have had 2 separate instances of an EGTreading that was way too high (even with engine off). Fault was traced to a pin not fully inserted in the 25 pin Dsub on the prefabricated EGT/CHT loom. Hope this is of help to someone. Jake J

I had a similar problem with 1 of 2 D100's - using a regulated bench power supply and slowly increasing the voltage it would 'start' at 12.4 volts, not before. Dynon suggested installing 5.0. Jake J

Mark Try a different value resistor from the standard 30 K Ohm - around 100 K Ohm should do it. Try different values up to 120K. Jake J

FWIW - I'd be checking the wiring/connector at the EDC end. ;) Jake J

It's just indicating the shielding is grounded at both ends. Jake J

Hi David I have done many Dynon installs, as you know, but never had any of these symptoms regardless of whether it's a Jabby or RV etc - the 'problem' must be something to do with shielding (Microair harness's typically use the shiels as audio ground) or grounding issuse IMHO. Not any real...

I had exactly the same problem - fixed it by running a wire from the sender mount block directly to the ground bus. Hope this helps. ps - we checked the system with a calibrated temp gauge first to confirn the difference. Jake J

A quick glance at the Honeywell page makes me think it doesn't have a NMEA or aviation format output, so it may not be able to interface with any external devices. But this is more a question for Honeywell. Ask them if it can output standard serial NMEA or Aviation data. If it does, it will...
