1) No problem with buying a higher wattage than you need, as long as it fits in the circuit. Resistors are rated for maximum wattage -- how much wattage they can take before they get too hot and fuse, burn, or permanently change their resistance value. Any less than full power, and they'll just be cooler. Higher wattage resistors are usually physically bigger, though, so you should keep that in mind if space is limited. 2) If your meter is OK, your 1.2 ohms might just be contact, wire and probe resistance. But you should check to see that it's not measuring on a higher range, because your two resistors almost certainly have different values. The one that says R39 is 0.39 ohms, and the one that says 39R is 39 ohms. Big difference, but if your ohmmeter is measuring megohms, they both look like a short circuit. Check things out carefully before you plug in the 39R one.Here's how the euro method of labelling resistors works:
R39 0.39 ohms
3R9 3.9 ohms 39R 39 ohms 390R 390 ohms 3K9 3.9 Kohms 39K 39 Kohms 390K 390 Kohms 3M9 3.9 Megohmsand so on. If you see three digits, that usually means a 1 or 2 percent resistor. For instance, 3K92 would mean a 3.92K 1% or 2% resistor. This isn't too difficult once you get the hang of it, and it's a lot harder to miss a "K" on a print than a decimal point, especially if it's a fourth generation Xerox.
Hope this has been of help.
Good luck Chris
