I have a spare 24V alternator. How 'bout double the power at half the 12V cost?  | | | | | Joined: May 2009 Posts: 4,533 Likes: 370 Member/2500+posts | | Member/2500+posts Joined: May 2009 Posts: 4,533 Likes: 370 | The 1963-1969 parts manual shows the alternator (Cessna 611501-0202 for 150 S/N 15064533 and up, which includes the 1967 model) as being rated at 60 amps, not 50.

It might not be the original. I have since found a 15v/60amp overhauled alternator.

Could just be a peak vs continuous output spec for the same alternator. But you wouldn't want to use a 60 amp fuse with an alternator not rated for 60 amps continuous. Fuses are typically specified to pass the rated current for an indefinite period of time, only blowing when the current exceeds the rated current. That is, a 60 amp fuse will never blow when passing 60 amps, even continuously. The time it takes to blow depends on the type of fuse and how great the overload is, but there must be an overload beyond the rated current for it to blow.

Joined: Dec 2003 Posts: 14,797 Likes: 551 | The OEM (Cessna) alternator is 60 amp. But the aftermarket alternators from PlanePower or JASCO are 50 amp. Perhaps you have one of those? See if there's an STC for an alternator conversion in your plane's paperwork.
If I recall, the JASCO alternator can only be rebuilt by JASCO (they withold the parts and data). I don't know about PlanePower's rebuildability, but they use a Nippondenso alternator so I would *think* it's easily rebuilt.
