Back again Andrew,
There is no power at the track or the terminals with LED lit.
I got a reading of 6.8ish from the regulator, is that ok ?

I deleted msg 724 as i needed to edit it and couldn't.

I took a voltage between U5/2 and ground and got 1.5ish volts ( the
junction of R32/R33)is this important ? It's a lot less than the Iv *0.175



Should I bump up the input voltage to 15 or 18 volts ? Its 12.6v at
pres but drops to 11.6v tother side of the Bridge Rectifier, could
things be too low ?

----------------------------------------------------------------------
Ok here is a cutnpaste from JMRI terminal, does "CD false " (Line 828)
give any clues ?

Line 44796 is what it said after I tried to change a CV.

Patrick, Yes, the + command switches the track power as well as the LED. With the track power on, the PIC pins should be toggling. Your DVM may show a voltage...

Patrick, The reply of !O in the JMRI log means that the SPROG detected a short circuit and turned off the track power. That's why you can't read any voltage. ...

Andrew, Following on from my previous post. I bit the bullet and fitted R100 (oR47) and in hyperterminal I got 8.89v (ac) on the track. Do I need more volts,...

Patrick, R100 is referenced in section 3.4.1 along with all the other output stage components. It is pretty crucial, as you,ve found. It sounds like it's...
