CC head diagnostic only shows 12.0 volts

[Eric Huppert]

Ed,

 

With over ten years of Type 44 ownership (at least 400k and  4x44's) I have
found that the cc head is generally roundabout 1.5 volts less than the
battery/alternator voltage. If the cc head is reading 12 volts I know I'm
charging! As someone previously stated, voltage drop through the wiring maze
is normal (at least in my case!) This is with new alternators, old
alternators, in-between alternators...

 

Normal IMHO.
