Folks.
Generators in cars had been replaced for a good reason. They don't produce juice at idle rpm. Cars mostly wait in idle rpm on traffic lights. Especially since the seventies. With some load of wipers radios, headlights and turn signals, cars would drain batteries really fast. Not so with airplanes. When you fly you should have more than 2000 rpm going. That gives plenty of juice from a generator. And this will happen until you cut the power over the fence. For the time before and after the flight, the battery takes over and the capacity of a battery is ample, even if you have to feed strobes , nav lights and a landing light on at the same time. Now, my landing light has to go off after take off, but everything else can stay on and will not overload the capacity of the smallest Delco Remy generator. One more thing. I know some guys can't wait to spend another 1k on their babies. Do it to the right things. Start saving for an engine overhaul - wing fabric recover - new interior. Something you really get a use from. A new Alternator will be just working great and the owner is convinced his money is spent right, but a freshly overhauled Generator will do as well , last as long and is in most cases still up to the mission. If some repair shops can not figure out the dirt simple system of a generator/regulator combo, that does not speak well for them.

Generators were fine on Model A Fords and cars long ago when there were no alternators, but notice how quickly they were all replaced with alternators when alternators became available? I used to be in the auto repair business, and can attest that generators failed at a miserable rate, you could buy a replacement at any Western Auto store, alternators rarely fail. I would bet that nobody here has replaced their alternator on their car with an old generator. It took aircraft a little longer to get converted over, but they eventually did. Costwise, more money has been spent by an IA troubleshooting my obsolete generator system than it would have cost to convert to a brand new alternator system - AND IT STILL DON"T WORK PROPERLY! The added charging power may be needed by the addition of many things electrical that were not around in 1946. My Ercoupe friend has an original generator on his coupe that has been overhauled, and he still has to carry an extra fully charged battery with him to power his GPS, thei original system will not carry his entire load of strobes, radio, transponder with encorder, intercom, etc. That "solution" is not for me. --- In [email protected], "Jerry Eichenberger" <jeichenber...@...> wrote: > > Ed - > > I haven't participated in this discussion.
