Flight manual discrepancy?

[Mike Busutil]

On page 43 the flight manual say's:

"The maximum normal charging rate of the generator is 100 Amperes."

 

Then there is a Caution note That says:

"The ammeter Should be checked Prior to Takeoff. Takeoff Should not be Attempted if the Generator is charging over 50 Amperes"

 

If 100 Amps is normal, why does it say not to take off over 50 amps?

 

Is the caution incorrect to state 50 Amps? Or is the 100 Amps Incorrect? When I check the system I am seeing a max of 50 Amps after the generator kicks in around 1500-1700 RPM and I throttle up.

 

Am I reading this incorrectly?

 

I posted this in the P-51D questions thread but it doesn't look like anyone visits that thread anymore....

Disregard...

 

I found more info on page 131.

 

"Check all of your instruments for proper function within normal parameters. In doing so, be sure to check the ammeter indicator showing proper charging form the generator. Immediately after takeoff, the rate of charge should not exceed 100 amps, dropping back to the normal 50 amps or less after 5 minutes of operation. If the charge does not reduce, turn the generator disconnect switch to OFF and return to the airfield."
