Strange electrical issues with my '72 Dodge truck

Well I found a bunch of sites trying to sell paperback copies for way too much and pointless CDs with a PDF on it (it's not 2004 anymore guys come on lol) but finally came across this site that actually lets you directly download a digital copy. Wow! lol

Service Manual, Repair Manual, OEM Factory Service Manuals for Autos & Trucks

Looks kinda sketchy like the site was made in the early 2000s and never updated but the reviews seem legit, I think tonight when I get home I'll buy one and see how it goes. Or put on my pirate hat and see what I can find that way heh heh, damn things should be free anyway.
