Charging Problem
 

Can someone help with a problem with a charging problem. In 2002 there was a post to replace the old Cessna 337 battery charging system by replacing with a Cessna 400 charging system. The person posted he had done so and had the STC and would share it with someone wanting to do the same. I would be greatful for any help on this contact or schematic of this upgrade.
Thank you with help Dale Campbell
