Thanks Electonic M and old coot88 for the ideas. I guess I know the right way to do such a job, but often there are 'tricks of the trade' that are guicker and/or easier, while being just as effective. I think old coot88's tip is one of those very ideas, for those without a meter at least, but like a meter the circuit still must be broken and the bulb wired in series.

As for me, I have one of the monolythic Hickok Model 209A "volt-ohm-milliammeters, which is primarily for show since I can't find the proper size lead plugs for the small leads which I may have one of, but I would need two for some functions. The lead that I have is brittle, but I could re-use the ends. I have the large screw in lead in good condition. I love the look of this unit and would like to put it to use some day, but that's likely another restoration in its self. I also have an old Simpson VTVM that needs calibration or something as well as a later solid state Simpson that works great. I like to take that one to work to confuse the 'super techs' and even engineers these days. That is what I will probably use for this horizontal output job since analogs supposedly do a better job at giving a good, steady readiing. Of course there is always a dime a dozen digital meter or two around. Mine is decent, but frankly I don't see a big difference between my KAL Equipment job and the ever so popular Flukes we use at work.

I think it is in another thread that this H.O. current is being mentioned and once I read to disconnect a pin that is grounded to the chassis and add a small value capacitor. Then someone else wrote that he didn't get a reading with a capacitor, but he did when he removed it. No doubt, with these threads you can't take every little thing to heart or you might never get a job done. There are too many variables like human and equipment error. But V-K sure a great place to get tips from the best of the best; many of whom were doing this for a job. That sure must have been a great time to be in the electronics profession as all of the home entertainment repair is gone. There are a few bench jobs in industrial equipment repair these days, but I will refrain from getting on that boring topic.

Thanks again folks! I'm feeling the Zenith exitement coming on! Once this coil is in place and with hopefully good results, I will probably be talking about getting the color back. I think I mentioned once before that someone sent me a crystal that is supposed to work as a replacement for the old type that supposedly often go bad. The new part looks almost like a blue disc capacitor. Hopefully this repair will be easy since the set had great color to be at least 20 years dormant, then it just went away completely to black and white, so probably not too difficult. I think its a capacitor frankly, but that's just because they are usually the problem with a long dormant set.
