farri Posted July 17, 2011 Share Posted July 17, 2011 2 separate bolts moulded into the rubber. They need constant inspection to ensure the structural integrity but I reckon they provide better shock absorption then if it was one through bolt. Yeah! You`ve got it, Pud!!! Frank.

pudestcon Posted July 24, 2011 Author Share Posted July 24, 2011 Another frustrating weekend!!! Got a lot done and we were ready to fire her up at 11am today - but I wasted a couple of "Clear prop!" calls and realised the starter was not going to engage. Some investigation work, and help from a local mechanic, showed that the starter had been assembled with the magnet assembly the wrong way around. So reassembled and reinstalled for 'take 2" at 2pm. Another couple of "Clear prop" calls were wasted - damn I'm getting sick of this!!!:ace:More investigation work - removed the spark plugs, plenty of fuel but no spark. Ran out of time to investigate the lack of spark situation but I suspect the wiring from the engine to the ignition circuit switches could be the problem. Another week goes by........

Pud Being new to all this, I never cease to be amazed at the rate of failure in what should be highly reliable aviation stuff. No spark in a brand new engine???? Stick with it Pud....you'll hear the cheers from all over Oz when you finally get into the air :big_grin: Link to comment Share on other sites More sharing options...

I don't believe the lack of spark is anything to do with the new engine. More likely that the wiring installed from the engine to the switches in the cockpit is faulty - that's our fault. Roll on next weekend and we'll find out. Pud Link to comment Share on other sites More sharing options...

Deskpilot Posted July 25, 2011 Share Posted July 25, 2011 You realise Pud, when you get it off the ground you'll have a bigger crowd than Kingsford Smith! Speaking of K.S., I popped in to see his Vickers Vimey at Adelaide airport last week. Such a sad sight. It stands in a dedicated "hanger", in the middle of a car park away from the main terminal, and was in total darkness. Protective screens have been erected about 4ft in front of the windows so no natural light enters the viewing corridor. Fair enough, but you'd think that the internal lights could be switched on so that interested people can at least see our most valuable aviation icon. It's said to be so fragile that it can't be moved into the new terminal building. Link to comment Share on other sites More sharing options...

winsor68 Posted July 25, 2011 Share Posted July 25, 2011 It will be worth it all in the end Pud...

pudestcon Posted July 29, 2011 Author Share Posted July 29, 2011 I've been doing some research work during the week on the lack of spark, plus I visited the hangar during the week for a quick inspection of the wiring. What I reckon is the problem, and it's easily fixed, is the wire connections from the engine to the various sections. What we have is confusing wire colours coming from the engine (Rotax issue) where we have (according to the schematic in the Rotax Operators Manual) both ignition shorting cables identified as Black/yellow, then a Black/yellow wire and a Yellow wire for the rectifier regulator. That seems to be what I have identified on the engine as well, where the Black/yellow wires have been interchanged. Tomorrow we will expose the wiring enough to see just what connections have been made where!! If I am correct then it should be a simple fix to swap the wire connections and fire up the engine. Just so long as the rectifier regulator has not been fryed in the process!!!! It's a Powermate so I'm hoping it will be robust enough to have withstood any power spikes.

Guest davidh10 Posted July 29, 2011 Share Posted July 29, 2011 You would think if they were going to re-use the same wire colour code, they would put them in separate harnesses or wind a different coloured strip around them to make for unique identification. Sounds like an easy error to make. Good luck Pud.

eastmeg2 Posted July 29, 2011 Share Posted July 29, 2011 Hi Pud, I think there is a brown wire coming out of the engine loom that needs to be connected tothe airframe/engine earth but does not appear in the basic wiring diagram and can easily be missed.

Pud Hi Pud Sounds like yes are onto something. Black / yellow stripe wiring is used on circuits so that when a switch is closed the engine stops. Enjoy the flying today.

pudestcon Posted July 31, 2011 Author Share Posted July 31, 2011 The ignition problem is rectified - as we suspected, a couple of wires connected incorrectly. The engine fires into life very easily and on the first turn over, whether from cold with choke applied or when warm. Further issues though..... Could not get the EGT gauge to register temps, thought about it overnight and sorted the problem this morning. Another issue with the water temp gauge not registering, the water temp sensor is a new one and registers an electrical signal with a multimeter at the sensor, and also at the connections to the gauge - sounds like a faulty gauge (this one is second hand) so will have it tested during the week. Last problem for this weekend is the tacho not reading in a steady manner - I can have 2500 rpm showing but the indicator will hunt at times between 2500 - 3500 rpm. Work to do here to eliminate this problem and will have the gauge tested during the week as well. So the run in procedure has not been completed due to not knowing what the engine temps are - next week maybe..... Pud PS. The engine sounds sweet though:big_grin: Link to comment Share on other sites More sharing options...

The engine sounds sweet though:big_grin: Hi Pud Don't give up on the gauges to fast. I did a check on a mates when his gauges would not work. Found the problem was with the wiring, make sure the wires connected to the back of the gauge are on the correct terminals. If they are back the front they will not work, just swap them over.
