1965 C337 "Alternator not charging" light

Thanks Dr. Dave. I'll check over the system-as soon as the temperature is a bit higher. My hangar is NOT heated and currently the temp is about 20 with about the same wind speeds. I didn't see the wiring diagram, in the MX manual, showing the "Alternator not charging" light? Do you have it or if not could you draw me the schematic? I checked out your panel VERY NICE! Are all the wires coming from breakers original aircraft wires or are you replacing the wiring as well?
Many thanks, BILLS

Hi BILLS:

The circuit wires on my panel are mostly original. The eight-place circuit bus is for the avionics. I'm doing the Approach Fast-Stack system. All of the avionics power wires will go to that bus and the grounds will go to a dedicated single-point ground bus for the avionics. I ran parallel #8's to feed the battery, these are replacement/upgrades. The original charge wire had a poorly crimped end that was burnt from a poor connection. The alternator feed wires are new all of the way to the alternators.

What is the serial number of your plane? I will look and see if I have the wiring schematic for the alternator system.

Hope it warms up there soon. We can certainly make a list of things to check so you don't spend too much time in a freezing hanger.

Hey Doc. My serial number is 337-200. A 1965 model. You know that when I was looking to buy this airplane, I did the PRE-BUY, I'm an A&P. I noticed the wiring from the regulators, looks like lamp cord. Insulators around the wires where all cracked. Last year I had a diode problem that took about three weeks to track down. I was thinking of installing Zeftronics regulators and possibly an updated alternator sensor that is installed on the 1968 models and beyond? I have a C337 parts bird, but it's a 1965 as well. Any suggestions in reference to the alternators going off line? Many thanks-in advance!
