This was intended to be a triumphalist posting but unfortunately it has turned out not to be, for reasons I’ll go on to explain. Wim dropped in this morning and helped me to lift MYRO’s old Rotax 503 onto 28AAD’s engine mountings. It only took a few moments and then it was just a matter of connecting things up and tightening nuts and bolts.<\/p>\n

Then I couldn’t resist it. I connected MYRO’s old battery up and the LED lit up when I switched the Master on. Then I turned the starter key and the starter motor kicked into life. So far so good.<\/p>\n

As the battery is now getting very old, I wondered if it would still have enough power to turn the motor over a few times, so I held the starter key on for a few seconds. That’s when it all went pear-shaped. The next thing smoke was billowing out of the right hand rear of the engine.<\/p>\n

The heat was sufficient to melt the plastic shroud on the engine safety tie that I’d only just fitted so there must have been some kind of electrical dead short, probably in the stator I’m inclined to think. Why I don’t know – I’m pretty sure without having checked again that I’d connected everything up properly and if so, there are two obvious possibilities. Either a fault had developed in the stator while it had been standing for the past four years in my ‘atelier’ (unlikely I’d have thought) or the voltage rectifier that I repaired the other day had got damaged in some way.<\/p>\n

If neither of the above, I must have connected something incorrectly, but I don’t see how I managed to get a dead short across the generator. For the time being I don’t know what the answer is, but it’s a major setback and an expensive one too, as a new stator costs north of 250\u20ac. It has taken the gloss off the fact that both the new screen and door plastics and the primer bulb were both delivered today \ud83d\ude41<\/p>\n

After checking the wiring, I’m still rather stumped. All the wiring that I connected looks to be in order, so I don’t think that I made a mistake. The only dead short that I could find was across the generator pair themselves, so it looks as though the fault was an internal one, I don’t understand why. The only component that is connected across them is the voltage regulator, so that still has to be suspect.<\/p>\n

So far it looks like a new stator (216\u20ac) and a new voltage regulator (108\u20ac) both from Loravia, so an expensive exercise. Was I wrong to try and repair the damaged regulator and that caused the problem? I don’t know, but when I come to sort this out with new parts, I won’t be able to take the chance. But for now, I think I must turn my attention to fabricating the new screen and then sorting out the couple of small things that I need to do on the X-Air.<\/p>\n

And then there’s the Savannah screen to finish off…<\/p>\n","protected":false},"excerpt":{"rendered":"
