Working on a buddy's project Night Rider.

I noticed that the 122-125 (not known good) did not have bridging over 5 & 7 on the transformer as shown on the placard in the back box.

1 & 3 were bridged, as were 9 & 11.

Anyone have a good reason as to why (5 & 7) this was gone?

I would think that those instructions should have been followed by the original machine installer.

TIA.

Quoted from BigAl56:

They may have omitted the jumpers for the 6.3v switched Il lighting to keep the output lower to preserver the lamps. What do the output voltages measure?

I'm not there yet - this was a bit of a basket case. I'll post back when I get other parts. Thank you!
