Controlled lamp issues here all...trying to diagnose. My feeble brain is getting old.

PF is out of the machine. No power, no nothing. Someone has replaced all controlled lamp sockets with 555 sockets.

If I am testing continuity from the lamp socket to the connector for the lamp driver board, why would I get continuity to the power braid stapled to the PF - all I can think of is shorted, crappy lamp sockets.

In a couple of cases if i pulled the lamp out of the socket the problem went away. But a large number of sockets seem to cause this.

Ideas?

Makes perfect sense! Thanks for the replies. I got the PF sorted last night and it works with an alltek board - so my wiring fears are of no worry.

Thanks again -
