my generator works ok, but the voltage is a little on the low side. it runs about 12.5 volts, and i think it would keep my battery at a higher level of charge if it were 13 or 14 volts. I read the manual on the delco regulator and identified the screw you need to turn to increase the voltage but i have no idea how much to turn it.
i know what i need to do is turn it a little bit and see what happens, but i was wondering if anyone else has ever been through this and about how much did you turn your screw? i turned it a bit and need to run it but i have to move an airplane to get it out of the hangar and i ran out of daylight yesterday.
i keep looking at that practically new alternator sitting on the shelf and thinking i'm nuts not to just install it. but if i can up my voltage by turning a screw, i'm thinking that's what i should do. no telling what i will get into making the alternator switch, and i hope to have a trip coming up next week, and i hate to make a major change without time to fly it to make sure everything is ok.

ps, the airplane i have to move is a j3 cub, belonging to a close friend who lets me fly it whenever i want. yesterday i flew it around for an hour and did a bunch of landings. what a great little plane. no wonder it's so popular. this one has a stroked 85 so it's very similar in performance to the old 108hp super cub, with the lyc o-235, my dad had for years. quite peppy with one on board and minimal gas. i flew it over to a neighbor's strip which is very short and hilly, and it was just made for such conditions. he has a carbon cub with tundra tires so he doesn't need much room. slipped it in over some trees and didn't even use 500 ft. getting real comfortable in it. flew the cruisemaster around the pattern twice too (at the homee strip, not the short one). the weather here is going to be bad for a while so i got my flying fix in while i could.
