I have to agree with Chuck mate. If you want get a good book like Marine Electronics
Bible or any other that looks like starting out wit Electronics
for Dummies and then getting serious. You can do major damage, start fires, distroy thousands of $$ in equipment
, maybe even kill yourself by getting it wrong. We all started out knowing zip about this stuff and learned along the way so be smart... learn now and try to avoid all the mistakes
I am sure I and the others in here could tell you about... if we were drunk enough to be honest that is.
Some very basic tips:
Always use very thick wire for DC runs. The smallest should be 2.5 mm and I really mean smallest, like for a GPS
or small LED. 6mm is usually more like the real thing.
Use the best switches you can find. I always use Airpax simply because they are tested and then tested again for commercial
aircraft and are really what they say they are, not like most "marine" switches. Trick: Check at the airport
maintainance facilities. They often have "out of date" ones you can get for peanuts or a case of beers for a dozen. That has to do with the rules for aircraft not if the switches are good or not. Otherwise think 100+$ each.
Take your electrical system
seriously, very seriously and it will give you years of trouble free service
. Fail to take it seriously and well its your back side after all....
