PIC of alternator restart battery's location

Hi there

Mine has a cover over the batteries, I should be at the plane over the weekend so I will take a few photos. This holds the batteries in place.

When items like this come up on the forum I suggest you use the SEARCH feature built into this forum. This particular item, D cell batteries, has been beat to death on the forum.

But I am never against another thread being started just trying to help those looking for info find it with the least amount of key strikes.

Hank, I know you have an older model 337 that is likely different, but the newer models don't use "D" batteries. Speaking for my 1978 P337H, there are 4 "C" batteries.

I did a search and found no good photos of the battery location, only some very dark, blurry attempts that I felt could be improved upon.

A site like this will often have several threads on one subject, but by reading them all, one can gain a unique perspective from each OP, resulting in a better overall understanding for the reader/member.

Cheers!

Yes they do.

Haven’t seen anything like that in cars or boats.

Is it to recover from a situation of zero battery voltage available in flight?

Actually, cars and boats are exactly the same. Their alternators will not make power without "exciting the field" which requires electricity from their main batteries. If you lose your electrical system in one of those, its not a big deal, safety-wise at least. At little different in aircraft flying hard IFR, as these were built to do.
