Topic: TNS 291

When I had our generator overhauled some years ago the chap that did it said it would be very easy to modify the circuit so a solid state unit could be used.. unfortunately he has suffered a sever stroke since and so cant help. I'm sure if someone came up with a suitable wiring diagram and part numbers a minor mod could be done!! (£86 cheque to the CAA )
I was suprised how helpful they were when I did the Trig transponder mod.

Bob, I will be documenting the mod I am doing with the Transpro unit so you are welcome to this info to pursue a UK mod.

Please remind me though.

Regards,
Dick

Many thanks, I'll add it to the "to do list" !

I finally had a chance to fly the plane yesterday.   The voltage was running between 28.4-28.8 with the revs in the 1800-2300 range.    I hope the old carbon pile hangs in there.   I'm still waiting for a final answer from Zeftronics regarding their type B regulator.     I think converting to a B&C alternator would be the best choice.   I'm waiting on some information from them too.   They make a small alternator for the LOM engines that would be perfect for the gipsy.

Good to hear that something is working out Dave.  The CMM gives a total range of 27.4 - 29.0V considering both pre and post H27 regulators so it seems to be on safe ground.

Does the B&C have the same spline so that the existing quill shaft can be used?  I have seen photographs of these on an engine but not sure of the details.

X-rayed the undercarriage castings on DCZ on Friday so awaiting the results with bated breath.
