I am starting on gauges for our '40 pickup. I've read a lot of posts on this subject, so I think I understand most of the issues. I will have to use an aftermarket gauge, since the original will not fit into the new tank. I've gotten a couple of sending units recommended here (Carpenter and Yogi's). I've also gotten some of the MC7806 voltage regulators ($0.39 each). I've got 4 different gauge clusters, but most sat out in the weather and look nasty. I need a good working gauge to figure out how to adjust the sending unit arm length and height. How can I test these gauges to find one that works? Can I briefly touch 6v across the contacts to see if the needle moves? When they don't work what is normally the problem and how do you fix it?
