'71 340 Duster has a short

Thanks Dubob, waiting on my buddy to come who's a lot smarter on this stuff then I am. That's a great idea...I'll start there with him holding the meter in the engine compartment and me pulling fuses...will post back what we find. Crazy day here with the drywall guy showing up to fix our ceiling from an air conditioner water leak from an improper install...now AC guy showed up too...will be good to get the Duster running again as we've had to push it in and out of our garage the past month to have access to the attic.
We did pull each fuse one by one and had continuity through it all...my buddy thinks the voltmeter and/or light bulb might be causing the continuity...we did close the doors so the door switch to the dome light wouldn't be a factor.
