Terry:  I was hoping I'd get a response like yours.  My sch. shows the 35Y4 and I'm having trouble following the pins 'cause it's a 35Z5.  I've been moving things around and got the pilot light working w/o burning it out but now resistor R102 (1200 ohms) is cooking when I crank it up to 110V.  I can't seem to find the right pin for the pos leg of one of the 33 uf caps ergo the burning resistor. I'll check resistance again. 

Thanks,
Rich

Absolutely no one is going to reverse engineer that circuit. Even the iron core is missing.RodB — 10:37 AM
