[TenTec] Need 962 diagram

[Mike Bryce]

Just an FYI

A lot of VOM meters, when reading ohms,  have the polarity of the test leads backwards.

You can easily trace the AC wires to the bridge,and the polarity of the other two terminals can be determined by following one wire to the plus side of the big electrolytic capacitors.

However, this is only with the low voltage of the meter, and does not say the cap is good at 12 volts.  Do you have a scope to do more defined testing of the parts?
