    Ammeter giving almost random readings

    I have finally got around to addressing a problem with my ammeter present from when I initially installed my D-180 2 years ago.   Basically the ammeter is little more than a random number generator. The pattern is for it to start about - or + 1 or 2 then to fluctuate up and down in sort of...

    ?roll steering

    Just a question to bring myself up to the latest. I have a D 180, AP 74 connected to a Garmin 296. One roll servo (SV32 in my Jabiru 430.) The GPS Nav is working well with the AP following the route beautifully till it crosses over a waypoint and then it turns and hunts to find the track...

    Can I do a straight swap SV for D180?

    I have been thinking of upgrading but the more I read the more uncertain I become. I have an Flight dek D180 with AP 74 and roll servo (planning on installing the pitch servo over Xmas break) with external compass. I have the jabiru 3300 engine hooked up with 6 CHTs and the EGTs. Can I just...

    Problem with test mode of servo

    I have just installed the AP74 and one servo (SV32) as roll servo with my Flitedek 180 in my jabiru 430. The problem I have is: When I go through the calibration setup it seems to do everything OK. When defining the left and right roll limits it seems to accept the limit of travel positions...

    are all black wires common earth?

    I'm rewiring my whole system to accomodate the AP 74 in the dash etc etc. I have a Flightdek 180. I am pretty sure I have seen the answer to my question somewhere but a search has failed to reveal it. Are all the black wires on both the 37 pin plug and the 25 pin looms connected to a common...

    Twisted Pairs

    I have been reading that any twisted wires are suitable and had a thought that I have a roll of cat5E networking cable. This has 4 sets of twisted pairs within the one bundle. They look like they are about 24 or 26 gauge solid conductor. Would that cable be suitable - would sure save me...

    Zeroing the skid and slip ball

    My Instrument panel in my Jabiru seems to have sagged a little on the pilot side. Presumably due to the weight of t he instruments etc in our hot weather.  Now my skid ball is reading slightly off to the left when the plane is standing on flat ground, with wings and body measured  horizontal...

    Interference with Microair M760 radios

    I have intermittently had problems with my set up in my jabiru J430. I have a D 180 flitedeck and two M760 Microair VHF radios with a four place intercom. Intermittently I get horrible interference through the radios ONLY on transmit. Receive is fine. When I transmit, the loud interference...

    broken CHT wire

    I managed to break one wire on one of the CHT ring probes while changing a sparkplug. The wire broke at the spot where it joins the ring.  I opened the crimp and got the rest of the wire out. I notice that it  (and all the other probe wires are welded together at the tip with a little bead-like...

    Erasing data in memory.

    I have been downloading the logged data in my D 180 while testing my Jabiru engine but the amount in memory is fairly large.   I was wanting to record small discrete tests but each time I have to download about 3200 blocks of data - some of which is data from previous running. Is there some...

    Abnormally high RPM with jabiru 3300

    Ran my jabiru 3300 engine for the first time on the weekend. The RPM sensor is picked off from the wire coming off the alternator as per manual. The RPM readings were all over the place but the general trend was: at true low enginerevs the dynon reading was reading very high - 4000+ but...

    contact switches reverse

    I am using contact 1 on a header tank float switch. In the closed position the dynon reads open and vise versa. Tried it also manually on the contact 2 wires - same result. Some how the internal sensors for these are reversed. Not a huge problem cos I just reversed the labels but its a...

    Inside Air Temp

    I aquired a K-type thermister  (extra to the probe used for OAT) and was wondering if I can hook it up somehow to measure cabin temperature and display the cabin temp somehow?

    D-180 and OAT readings

    I have an OAT probe (two wire type) connected to my D180 and I tried to test the accuracy of the readings. Dipping into a drilled out hole in a block of ice got exact zero degrees centigrade but dipping it boiling water got only up to about 66 degrees. Is this a problem with the probe or a...

    D-180 and Garmin 296

    A question about installing the Garmin 296. I have connected up as per all the advice given on this forum - thanks for that- but my specific problem is that I am still in the process of building my jabiru. It is still in the shed and while in the shed gets no GPS satelitte access etc. The...

    Oil Temp and Pressure readings off scale

    I have installed a D 180 with a Jabiru 3300 engine (which has not yet run) and am having a problem with the oil temp and Pressure readings. The engine has no oil in it yet and is sitting at ambient temp in the shed. When I connect up the oil temp and pressure probes to the dynon they both...
